1. 'Growth' policy and why it's important to get it right

============================================

There is a widespread view among environmentally minded people that 'growth' must be stopped if the environment is to be protected and resources conserved. Now that environmentalists are taking up the challenge of devising economic strategies and are actively pursuing the creation of a green economy, two question must be answered:

* is it right to oppose all instances of 'growth'?

* what would be the effect of trying to implement policies designed to stop 'growth'?

The position that people take on growth is important for more than intellectual reasons. The economic policy measures that people advocate will be strongly affected by their beliefs about economic growth. If their understanding is inadequate or faulty then the policies they advocate are likely to fail and may even be quite damaging.

This paper takes a number of positions that differ from the usual 'pro' growth or 'anti' growth stereotypes. It argues that:

* growth in the use of physical resources and economic growth are not the same thing

* growth in the use of physical resources is the main cause of environmental damage and resource wastage and it is this growth that must be stopped

* economic growth should not be a goal of economic policy and that it should not be automatically promoted or opposed.

>From an environmental point of view a major conclusion is that if policies were put in place to stop economic growth, the transition to a conserver or green economy would be slowed down dramatically and might even be blocked.

So it is critical from an environmental perspective to get the 'growth' issue right.

2. The environmental debate over 'growth'

===================================

The very high rates of economic growth experienced in the three decades after the Second World War in the rich countries, and for a longer period in the rapidly industrialising countries, were accompanied by massive increases in environmental damage and resource wastage in many countries across the world. In some areas of both the poor and rich countries the development that generated this economic growth also caused major social disruption.

It was therefore not surprising that many people drew the straightforward conclusion that this growth was bad and should therefore be opposed. Unfortunately the analysis was not fine tuned enough. Opposition to this growth became opposition to any growth.

The fundamental confusion was between the effects of growth in the use of materials and energy and growth in economic aggregates. While general opposition to growth is well justified in relation to physical resource use, it does not, as will be demonstrated, make automatic sense in relation to economic growth.

3. What is economic growth?

==========================

Economic growth measures the percentage change in economic output in an economy in one time period compared to an earlier period.

This is not a measure of physical product or physical throughput. It measures the money values of products (both services or goods). In this context a product is anything that people are prepared to pay for. So it is irrelevant whether the product is intensive in its use of physical resources or not.

Economic growth has always measured both the physical and the qualitative expansion of output. Since until recently physical output expansion has overwhelmed quality increase, economic growth has seemed to be a measure of increased physical output. If output increases were mostly qualitative improvements then economic growth would appear to reflect improvements in quality rather than increases in physical output.

The reason why economic growth must reflect both increased physical output and quality improvement is as follows. Economic output can be said to have expanded if, after correcting for inflation, the real money value of all production has risen. How is inflation measured? A representative range of goods and services are examined by bodies such as the Australian Bureau of Statistics. The current price of each good or unit of service is compared with its earlier price. If the goods or services are physically identical then price changes reflect inflation or deflation. But the goods or services in particular categories (e.g. photocopiers, margarine, medical services, etc.) that are produced in one period are rarely identical. There are usually quality improvements or declines as well. So before the inflation rate can be determined, these quality changes have to be estimated as a percentage change and then the quality-corrected price of the goods and services can be compared over time.(1) With all this information in hand it is then possible to estimate the rate of economic growth.

4. Economic growth does not measure welfare

======================================

Economic growth does not measure social welfare. However, it has been considered to be a useful measure by many politicians and economists because high rates of economic growth have often been associated with:

* higher employment levels

* higher average income levels

* greater equality of income distribution.

These three factors are widely considered to correlate with overall social welfare. In some situations the correlation can be strong but in other situations it is very weak.

For example, contrary to normal expectations:

* total social welfare could decline despite an aggregate increase in the size of the economy if most people's income were to decline. (Growth in the economy with reduced incomes for most people could occur if the increased wealth and income concentrated in a very few hands)

* total social welfare could fall despite increases in employment if family care and other community development functions, previously done voluntarily, were no longer done to an adequate degree, even on a paid basis.

5. Economic growth does not measure environmental impact

=================================================

Economic growth does not measure environmental impact or the depletion of resources. However, it has been considered to be a useful measure of these changes by many environmentalists because, to date, high rates of economic growth have usually been associated with:

* rapid depletion of physical resources

* rising pollution levels

* destruction of natural systems and species

* loss of urban and rural amenity.

However this correlation could break down if resource conservation and environmental protection became a major preoccupation of society. For example, if all new investment was selected on the basis that it not only increased economic productivity but also reduced the level of environmental damage and the consumption of non-renewable resources, then there would not be a close link between economic growth and environmental damage and resource consumption.

6. Should we promote or oppose economic growth?

==========================================

By definition, economic growth is directly correlated with only one thing - the level of economic output compared to an earlier period. What this means in the real world for either environment or social welfare cannot be determined until the detailed character and impact of the economic production is examined.

For example, just because the production of a certain quantity of particular goods and services creates a net human welfare gain, it cannot be assumed that more of those goods and services will produce a proportionate further increase in human welfare. If the need for a good or service has been virtually saturated, the net welfare generated by an increase in production would, most likely, be less than proportionate and may even be negative. Alternatively, the increasing abundance of a good or service might lead to greater awareness of how to use the product or may lead to it being used more actively, in which case there could be a higher than proportionate increase in human welfare if an additional increment of the good or service was produced.

Even though it has been very common for negative environmental effects to be caused by increased economic production, it cannot be assumed that this must always be the case. If additional products were used to consciously improve the environment and conserve resources, then having more of these products could well be environmentally beneficial. Or, if the production of products with potentially negative effects was coupled with other economic activities that prevented the potential negative impacts or compensated for them, then the net effect of increased production may not be negative.

So the critical conclusion is that economic growth should be neither automatically promoted nor automatically opposed. Before making any judgement, the actual character or content of the economic activity should be examined. Increased output of products which, when taken as a bundle, boosted social welfare and environmental protection/resource conservation should be encouraged (i.e. there should be positive economic growth) while activities which, when taken as a bundle, reduced social welfare or reduced environmental protection/resource conservation should be wound back (i.e. there should be negative economic growth).

So the focus should not be on the total level of economic activity in the abstract, but on the content and proportions of 'good' economic activity versus 'bad' economic activity.

Changing the character of economic activity is much more important than just boosting or contracting the economy overall.

Being fixated on economic growth (to boost it or oppose it) is rather like trying to drive a car by looking at the speedo rather than the road (i.e. the destination) or like playing tennis by watching the scoreboard rather than the ball.

7. Is it possible to have economic growth in a profoundly green economy?

==========================================================

An ecologically sustainable economy would be one in which current physical resource demands were:

* reduced dramatically, i.e. by at least * of the present consumption level, and then stabilised

and the production system changed so that there was virtually:

* 100% recycling

* zero pollution discharge

* 100% reliance on renewable energy, and

* zero loss of native species and ecological communities.

An economy could only meet all these requirements for any length of time if the population was not growing. Indeed in many countries the task would be easier if the population stabilised at a level lower than the present one.

Economies will have to adopt this physical profile if greenhouse warming is to be stopped and a range of other environmental problems overcome.

The human needs that an environmentally sound economy would have to meet are of two broad kinds:

* bodily needs such as food and water, shelter, warmth, waste disposal, etc. These are material needs

* psychological needs such as love, self worth, stimulation, community, sense of place, fulfilment, etc. These are potentially or actually non-material needs.

So is it possible for economic growth to occur in such an economy?

Economic growth (on a per head basis) occurs when one or more of the following happen:

* productivity rises due to an increase in the quality of goods and services (and working hours do not fall)

* productivity rises due to an increase in the number of units of goods and services (and working hours do not fall)

* more hours are worked through more people being employed or longer hours are worked per employed person (and productivity hasn't fallen)

Increasing the hours worked cannot produce economic growth in the long term since eventually full employment is reached and there is a limit to how many hours individuals can and should work.

There is a complex limit to the number of goods and services that can be provided. The need for the economy to be ecologically sustainable sets an upper limit on the total amount of physical resources that will be available for making products and providing services. Available time sets an upper limit on the volume of services that can be directly experienced by final consumers. Given these limits greater numbers of products and services can be created if they become less resource intensive. However, technological advance, the characteristics of the production and lifestyle infrastructures and the material or bodily needs of humans set the limits on how low resource intensity can go.

There does not seem to be any obvious theoretical limit to how far the quality of goods and services can be improved. However, the rate of quality improvement is limited by the speed of improvement in technology and the rate of evolution of lifestyles or ways of living.

So the ways in which economic growth can occur in a profoundly green economy appear to be as follows:

* while there is unemployment and underemployment, increasing the hours worked can result in economic growth

* for as long as technology can reduce the necessary resource intensity of goods and services then increases in the number of goods and services can result in economic growth

* since quality improvements in the 'service' value of goods and services seem to have no clear limit, they should be able to allow economic growth to continue indefinitely.

Economic growth per head could occur despite overall resource constraints while:

* the population was declining.

(The rate of decline cannot be too high or there will be welfare losses rather than gains due to burden of increased old age dependency and because infrastructure would have to be scrapped well ahead of the end of its economic life.)

So the possibilities of increasing welfare per head (a better goal than economic growth per head) seem to come down to the following:

* stabilising the population (perhaps at a reduced level)

* increasing the resource efficiency of producing, delivering and using all goods and services

* ensuring that the non-material needs of humans are met as far as possible in a non-material way (i.e. dematerialising the services and goods that are used to meet peoples non-material needs)

* wherever possible, improving the quality of goods and services rather than increasing their physical quantity.

These four strategies would require an interplay between improved information, modified infrastructure and institutional arrangements and changed lifestyles.

In effect what these strategies do is:

* in the near term, lower the physical resource demands of the economy to a new, very much lower level while maintaining real welfare, and

* extending beyond the near term into the distant future, generate welfare gains through qualitative improvements in services and goods (without requiring additional physical resources). These qualitative improvements would register as economic growth.

So to come back to the question posed at the start of this section: there are in fact theoretical circumstances in which economic growth could occur in a profoundly green economy.

8. Is it likely that economic growth will occur in a profoundly green economy?

=============================================================

It used to be routinely assumed that if there was a reduction in the physical resources available to the economy there would have to be a fall in productivity. However, physical resources are not the only factors of production.

The factors of production in any advanced economy are:

* labour (unskilled, skilled)

* information

* plant, equipment, technology hardware

* 'land'

* recycled materials

* recovered energy

* renewable energy (direct solar, hydro, wind power, biomass, geothermal, etc.)

* renewable materials (wood, fibre, food stuffs, water, etc.)

* newly extracted non-renewable materials (minerals, etc.)

* newly extracted non-renewable energy (coal, oil, gas, uranium).

If the total input of physical resources into the economy is to fall dramatically then overall productivity must be maintained by increasing the use of other factors of production. Given that recycled materials and renewable energy are often (but not always) more expensive than newly processed non-renewable resources, the main factors of production that must be relied on to maintain productivity are:

* skilled labour

* sophisticated machinery and technology

* information.

All three of these factors are in fact the product of or are highly influenced by the information industry.

A strategic analysis shows that the move to a profoundly green economy could, far from bringing economic growth to an end, actually make it easier to continue high levels of quality driven economic growth for longer.

Measures to create an ecologically sustainable economy are likely to boost the growth of economic productivity and gross econmic output by:

* favouring dynamic sources of growth rather than static efficiency, for example, galvanising the economy more effectively around the information industry which is now the biggest source of economic growth;

* requiring a very close focus on the needs of the customer thus increasing the chance of creating added value and trade competitiveness(2);

* creating greater producer awareness of product quality over a full use cycle and the incentive for producers to maximise product lifecycle efficiency due to the adoption of lifetime leasing, take-back or extended product responsibility policies;

* creating a strong focus on total system design and total system efficiency and effectiveness(3);

* making it politically easier to favour savings (and hence investment) over current consumption;

* fostering an acceptance of investments with longer term payoffs (lower discount rate);

reducing the loss of productive capacity caused by high unemployment;

* reducing the cost of supporting unemployed people and reducing the cost of handling the negative externalities generated by higher unemployment;

* shifting from a focus on the growth of labour productivity to total factor productivity;

* in time, favouring the retention of employees in firms during economic downturns thus retaining skills and providing a more effective base for productivity improvements and innovation(4);

* eventually making urban renewal cheaper than greenfields development thereby reducing the waste of urban and social capital involved in urban decline(5);

* requiring Australian product exporters to better meet the environmental needs of the high-population countries thus boosting the economies of scale available to industry by making it easier to access larger markets;

* improving economic efficiency by reducing materials throughput(6);

* by improving the efficiency of stock utilisation by final users(7);

* by accelerating the introduction of the paperless office, by reducing traffic gridlock(8) and by reducing the cost of servicing urban allotments(9);

* more effectively tapping the productivity boosting effects of new, smaller scale and decentralised renewable energy technologies. These technologies can be mass produced thus achieving economies of scale and dynamic production advantages compared to the relatively few but massive energy projects that dominate energy production now (Flavin & Lenssen, 1995);

* reducing the drain on the economy and on wellbeing caused by environmental damage and the depletion of high quality resources. (The economic cost of avoiding these problems would be much less in a profoundly green economy that radically restructured to avoid them than it would be in a moderately green economy that had to do a lot of remedial work.);

* reducing the social log jam over development. (This is especially important for economies like Australia which are currently very resource intensive.);

* contributing to the ecologically sound creation of wealth among the poorer sections of poorer countries that is not heavily dependent on exports to the rich countries(10);

improving local economic development multipliers because it is easier to identify good investment opportunities (related to environmental improvement) with a consequent higher rate of retention of locally generated investment funds.

It might be useful to use a parable to illustrate the way economic growth could occur in a very green economy.

Interlude: The People's Green Utopia

==========================

The green revolution had succeeded and the People's Collective met to decide what to do. It was well known that the evil capitalist growth machine had very nearly destroyed the Earth (with some help from the only recently demised evil communist growth machine).

The members of the People's Collective sat in a circle and after the appropriate rituals of celebration and ReEarthing turned to the question of what should happen with the economy. The issue was workshopped extensively until a consensus emerged. The Collective recognised that while they knew what they were against they were not completely sure what they were for. So a thorough process of consultation would be needed to determine what the revolutionary economy should look like. One thing was clear however and that was that any new economy would have to be totally ideologically sound - showing a deep respect for Gaia and all beings of the Earth, both human and non-human.

So the Consultation began. For three years it ran. In the meantime no new economic initiatives were made. The more outrageous aspects of the consumer economy were closed down and people shared out the reduced working hours and take-home pay. Solidarity was strong and spirits were still high.

At the same time, unknown to the People's Collective, an underground movement was developing among the few remaining accountants who had not fled to Singapore after the revolution. They were determined to maintain the faith. They had seen the USSR crumble after 80 years. So they felt it was their duty to the capitalist way to document the folly of the new regime. In time people would tire of putting the environment ahead of the economy and the truth that the accountants would document and spread through their samizdat publications would eventually undermine the evil green regime. During those first three years the accountants, meeting secretly in twos and threes, built up a wonderful picture. Their data showed an economy in deep recession with production, working hours and income declining, investment stalled and an increasing level of uncompetitiveness in the traded good sector. Even more exciting was the fact that the consumption of energy and other resources and the production of pollution was still surprisingly high, recycling schemes were in crisis for lack of markets for the collected material, no meaningful progress had been made in introducing renewable energy sources since few could afford them, and soil erosion was on the increase because of a lack of public and private funds. So the People's Green Utopia was even failing on the green front.

Then the Great Consultation came to an end. The consensus had been reached. The transformation of the economy could begin.

The people of Green Australia would no longer worship economic growth. The false idol had been toppled. Only socially and ecologically useful initiatives would be permitted. The money system would be based entirely on ethical investment and the rest of the economy would run on LETS Schemes. Instead of large companies, small empowered work units would be promoted (with a wide range of legal structures) and these would be intensively networked and supported by an array of small supporting businesses.

The transition to a renewable energy base would begin immediately, virtually fully recycled products would in time become the norm, a target of zero pollution and 100% recycling would be adopted for industry and the public. Urban areas would be reshaped to drastically reduce dependence on the car. Degraded environments would be repaired and natural areas protected. The residue of the consumer mentality from the old society would be snuffed out. A compulsory savings scheme would be used to soak up spare money that might otherwise be spent on trivia. In recognition of the environmental and social disaster in the making in Asia, as it developed under the virulent Asian variant of capitalism, Green Australia would re-orientate its entire export program to promote "conservation, wellbeing and empowerment". Exports of physical resources would be cut. Instead Green Australians would work in grass roots partnerships to promote the greening of Asia and the elimination of poverty. The People's Rolling Plan recognised that action had to be taken urgently if the Earth was to be sustained and poverty ended. The 17 million people of Green Australia would have a lot to do over the next 20 years if they were to meet their ecological and social deadlines.

Behind the scenes the dissident accountants prepared to record the next phase of the Green Madness. The last three years had been bad enough, with Australia turning its back on the only successful form of economic development known to Man (sic). Now these Green Australians were going to take the stalled economy and throw it 180 degrees into reverse. The current disaster would rapidly become a catastrophe.

Oblivious to their fate, the Green Australians pressed on. Now that the prohibition on initiatives had been lifted there was actually a discernible sense of optimism and energy in the air. Extensive visioning and training exercises conducted in the previous three years meant that people had a good idea of what sorts of initiatives would be desirable. They knew that all new projects would be vetted by People's Review and Improvement Committees and it could take a project quite a while to get through this process if it wasn't pretty good to start with. So people set to with some enthusiasm to pursue the new directions. Grass roots links with Asia and the West Pacific were developed apace. The social and environmental needs were so great that it looked like you could involve almost everyone in Australia in some way.

At the end of the first year the network of the Accountants for the Restoration of Sanity and Unfettered Capitalism (ARSUC) sprang into action to calculate how the economy had gone over that time. As the results came in a flicker of puzzlement developed in the minds of the few key analysts who were allowed to access the full data set. The free fall the economy had been in during the previous four years had slowed dramatically. Net production was still lower than the previous year. But what used to be known as consumer confidence was up and personal spending had risen significantly mainly because of personal investment in new initiatives. However these results were clearly abnormal, possibly due to the booming Asian market and the short lived effect of lifting the three year initiatives ban.

In the second year many of the first year's projects picked up steam. People were gaining experience. The networks were getting more effective. Inventive types were developing better ways of doing things. This freed a bit of time and resources to devote to some of the other pressing initiatives that had to be put off the previous year.

When the second year ended the accountants of the Central Data Analysis Group of ARSUC found the economic indicators to be poor again. For the first time since the Revolution production levels in the economy hadn't fallen. This had to be due to some abnormal event or it might even be due to errors in data collection or processing. So a special task force was set the job of searching for any errors.

During the third year the Green Australians quickened the pace of rebuilding their industries, cities and farms. The global support and solidarity networks established with greenies around the world in the years before the revolution were starting to produce unexpected results. Throughout the networks people were hearing about the new sense of direction and purpose being shown in creating a green economy in Australia. Ethical investment funds, alternative technology groups, a significant number of individuals in mainstream companies and government agencies, and even some semi-mainstream companies became very excited and stared to get involved with projects in Australia. Knowhow, money, markets ..... the global village turned its attention to the green and just opportunities that were emerging in Australia.

The ARSUC task force reported. There had indeed been data errors. It was inevitable given the difficulties the accountants were working under. But the errors had effectively cancelled each other out. So it was true! The economy had stopped contracting!! In fact the figures for the year just passed showed that while physical resource use was 25% lower than the pre-revolutionary high (and was projected to fall much further), economic output had actually expanded! What was more remarkable was that one ARSUC member, on a whim, had divided the economy into those elements that were the mainstream in the pre-revolution economy, and the new elements introduced since the revolution. The bulk of the economy was still pre-revolutionary in character but the pre-revolutionary sector was declining steadily. What was extraordinary was that the new elements of the economy, although starting from a very small base, were expanding at over 30% per annum. At that rate aggregate economic production would significantly exceed the pre-revolutionary levels within 10 years! The Central Political Committee of ARSUC was called into emergency session.

-----

The People's Collective of Green Australia was called into emergency session. A group of university based green economists had recently done some analyses of the economy to definitively and empirically prove at last that social wellbeing and environmental quality could rise, and the economy could operate viably with an ecological sustainability target, while economic growth fell. To their total amazement what they found was that after the initial massive slump following the revolution, economic growth had stopped being negative and was now back to the pre-revolutionary long term average (about 2% growth). But more remarkable than that, the long run projection was for the economy to actually start growing in aggregate at about 8% per annum within the next 10 years.

This news flashed around the electronic networks and across the country within hours. Messages of dismay and confusion poured into the Bulletin Boards and specialist 'conferences'. Recommendations started to build and soon grew into an avalanche. A dominant theme was that something would have to be done immediately to stop this economic growth. It would be necessary to reimpose the earlier ban on initiatives and then to put in place a rigid system to ruthlessly weed out all ideologically unsound projects. While this discussion was going on, other people on the network started to analyse the national accounts more carefully. The tasks were divided between ad hoc volunteer task forces. Within two days the results came in.

There was no fault in the project assessment process. While many Australian projects both domestically and internationally were still a way short of the ultimate goals of 100% recycling, 0% pollution production, 100% renewable energy base etc. they were almost universally within the trend band that had been set earlier to judge ideological soundness!

There was only one conclusion that could be drawn. The single minded but innovative and entrepreneurial pursuit of the ideal had inadvertently generated economic growth and high levels at that! Significant contributing factors were:

* the very high savings rate (one of the highest in the world, just slightly ahead of Singapore)

* the low failure rate of Australian investments aimed at helping the poorest people in the Asia West Pacific region to become better off, and the fast spiral of productivity improvement that socially and environmentally appropriate investment set up in these communities

* the high demand in both high and low income countries for environmentally and socially sound technologies and systems developed or 'packaged' in Australia.

* the dynamism of networks of small businesses when they had good back up and access to capital

* the dynamism that the Australian economy gained from shifting from reliance on the minerals and primary production sectors to the information industry, and the personal services and elaborately transformed manufactures sectors

* the reduced need for defensive expenditure as environmental damage declined, health conditions improved and community cohesion increased.

The green economists and indeed the whole nation went back to their theory and began to revise some of their central assumptions. It was now clear that economic growth is a resultant not a goal. It should be neither pursued nor opposed to its own sake. Both actions would be a fetish. The key issue was what the economy does and what it produces. If the economy delivered high levels of wellbeing and fulfilment and it was also truly ecologically sustainable, then that was all that mattered. Whether the national accounts showed growth or not in these circumstances didn't matter.

Historians of Green Australia don't know what the ARSUC accountants thought about these questions because extensive searches revealed no further records of the group. It appears that the group fell into disarray and was eventually abandoned.

9. Will economic growth always cause inequality to increase?

=================================================

Economic growth per head is caused by increasing working hours or increasing productivity. There is nothing in this that automatically means that growth will either increase or decrease equity - either within Australia or between Australia and other countries.

During the post Second World War boom, in areas such as the US, Europe, Japan, Taiwan and Australia, economic growth correlated with increasing equity in wealth and income distribution. In many other countries, and indeed in the US, Europe and Australia in more recent times, growth has occurred alongside increasing inequality in wealth and income.

Which way it goes really depends on whether or not the economy that is expanding favours the creation of jobs for the low skilled. For nearly three decades after the 2nd World War in US, Europe and Australia it did. In more recent times in these areas it has not.

The solution to the equity problem is not to promote or oppose economic growth as such, but to change what the economy does so that the currently unskilled become skilled or so that productive jobs are created for the unskilled.

10. Surely environmentally sound economic growth cannot go on forever?

=========================================================

Even if people concede that economic growth could be managed so that there were no negative environmental effects for a period, most growth critics believe economic growth could not occur for any extended period without a re-emergence of environmental problems.

To some extent this must remain an open issue since we have never before tried to run a truly environmentally sound industrial economy for even a short period. However, there is one point of comparison that could indicate what can be done. Life has existed on the planet for over 3* billion years. During that time life has had to cope with a fixed supply of materials and a roughly constant energy supply. And yet there has been continuous evolution or 'development' of the forms of life on the planet and the ecosystems they make up. For most of the 3* billion years, this 'growth' has been caused by 'quality' improvements (evolutionary development within species, increased numbers of species and the growth of complex multi-species communities) rather than increases in the total mass of living things.

Most green or ecological economists now recognise that while physical growth in economies cannot occur for more than short historical periods without major ecological damage, qualitative development could continue indefinitely. However what is not generally recognised is that economic statistics make no fundamental distinction between quantitative and qualitative growth. Hence if the economy were to shift from unsustainable physical growth to sustainable qualitative development the economic statistics would simply show continuing economic growth.

11. The policy implications of a more accurate understanding of the growth issue

==============================================================

It was asserted at the start of this paper that "if [people's] understanding [of growth] is inadequate or faulty then the policies they advocate are likely to fail and may even be quite damaging". Hopefully by now the error involved in being either automatically for or automatically against economic growth should be clear. It is now time to turn to the policy implications of having an accurate or an inaccurate view of economic growth.

These implications are best demonstrated by looking first at the policy errors that arise if one believes that economic growth is either automatically a good thing or automatically a bad thing and then by looking at the appropriate policies that emerge if the accurate view is held that economic growth is not automatically good or bad.

11.1. "Economic growth is always good": Some policy errors

----------------------------------------------------------------------------------

Many people erroneously think that economic growth automatically has a number of positive attributes and that the higher the rate of economic growth the faster or more fully the benefits can be gained. Economic growth is assumed to automatically create:

* full employment

* high average incomes

* more egalitarian income distributions

* social harmony and cohesion

* the wealth needed to protect the environment and overcome social problems

* the capacity for an economy to be competitive into the future.

If people believe that these benefits automatically flow from economic growth they are likely to promote policies aimed at creating high rates of economic growth without paying attention to the quality of that growth, or to the substance of what is being produced including its life cycle effects. The indiscriminate promotion of growth may worsen the very problems it is meant to solve and may create other unintended negative side effects.

For example:

* if economic growth is being caused mainly by investment in labour saving equipment or systems, then more of it will probably worsen the prevailing level of unemployment

* if economic growth is being caused mainly by investments that are only viable if low wages are paid then the average wage could be very low despite any economic growth (e.g. UK at present)

* if economic growth is being caused mainly by investments that are dependent on very high skilled people (and not much is done to raise the skills of the currently insufficiently skilled so that they can participate in the new employment) then income distributions could be very inegalitarian and more growth of this type could make the situation worse

* if economic growth is being caused mainly by investments that cannot utilise existing workers even with retraining or the location of new investment is far from the old investment or the new investment cannot support high wages or there is little need for low skilled workers or there is inadequate retraining for workers (regardless of their current skill level), then economic growth could lead to social dislocation and community breakdown

* if economic growth is being caused mainly by investments that create irreversible environmental or social damage or the profligate use of non-renewable resources or if it causes environmental or social problems that cost more to fix than the economic surplus that is generated, then environmental and social problems could be made worse despite the wealth generated

* if economic growth is being caused mainly by investments that do not require local entrepreneurial or technological skill or that are concentrated in the same very narrow specialisation, then that form of economic growth could leave the economy very vulnerable to future technological or market changes because there will be little capacity for adaptation.

People who have committed the intellectual error of being indiscriminately in favour of growth need to recognise that certain types of economic growth are better that others and that some forms of economic growth should not be supported at all since they are worse than no growth at all.

11.2. "Economic growth is always bad": Some policy errors

--------------------------------------------------------------------------------

A significant number of people erroneously hold the opposite view that economic growth always has negative features and no economic growth can have any desirable features overall.

Economic growth is assumed to automatically cause:

* the destruction of the natural environment

* wastage of non-renewable resources

* increasing levels of toxic waste and pollution

* social inequality

* the intensification of materialistic values.

If people believe these ideas they are likely to oppose any policy that might lead to economic growth (e.g. high savings and investment rates) and some may even argue for policies that are specifically aimed at preventing any economic growth (e.g. arguing for a decrease in the general capital intensity of the economy). Such indiscriminate policies could make it impossible to achieve desirable environmental and social goals. For example, solar energy is more capital intensive than coal based electricity production (the ratio of up-front costs to running costs is greater) but that is no reason to oppose solar energy.

Economic growth need not be automatically associated with the negative features described above if the right policies are implemented effectively.

For example:

* if a general prohibition on the further clearance of native vegetation and habitats was introduced; if companies undertook biodiversity life-cycle assessments along side the pollution, waste and energy audits that many of them do now and then undertook product and process redesign as a result; if industry sectors were restructured to maximise the use of recycled material, to reduce resource intensity generally and raw materials were drawn from already cleared areas rather than from native habitats; if population growth ceased (and even fell for a period); and if major efforts were put into restoring damaged habitats, maintaining existing habitats and recreating 'natural' habitats to help overcome the past loss of habitat; then economic growth based on quality improvement rather than increases in the quantity of physical goods could coexist with the maintenance of nature

* if a suite of depletable resources and waste disposal taxes were introduced which grew with the size of the economy and if structural adjustment programs were put in place to help industries and communities to adjust, then the economy would actively conserve non-renewable resources and switch substantially to renewables despite any economic growth that might occur

* if zero waste discharge targets were set by industries to guide their continuous improvement programs and if waste discharge/disposal taxes were introduced which grew with the size of the economy, and if the industrial ecology principle that 'all wastes should be treated as raw materials for other processes' were adopted, then the level of wastes discharged to the environment should fall dramatically despite any economic growth

* if industries and governments favoured investments that on balance were more labour using than labour saving and favoured investments that enhanced the skill levels of those currently with lower skills; if wage subsidies were introduced for the relatively unskillable; and if generally redistributive policies were adopted or strengthened; then social equality should be enhanced despite any economic growth

* if ethical investment was the norm and resource taxing and other policies favoured development based on qualitative improvement rather than quantitative expansion, then non-materialist values would be favoured regardless of any economic growth.

If policies were adopted to block any possibility of economic growth, these policies would almost certainly also block the rapid emergence of a conserver society or a green economy.

The most important cause of economic growth is increased productivity and the main contributors to productivity growth are:

* technological and organisational innovation

* investment.

Innovation requires research and development and education. Investment requires savings or profits. A consequence of increased productivity, in particular increased labour productivity, is that the capital intensity of the economy rises.

Economic growth could be stopped by putting a block on all forms of innovation and all investments. It could be slowed down by stopping research and development and education and by reducing savings or blocking lending from savings accounts.

However it will take a great deal of innovation and investment to:

* restructure urban areas to be energy conserving and minimally car dependent

* rebuild manufacturing industry so that it approaches zero pollution and zero waste dumping

* create a renewable energy base for society

* convert farms to sustainable agriculture practices

* restore the land and control environmental pests

* eliminate poverty and create full employment.

The investment task is even bigger if, to meet environmental deadlines, previous environmentally unsound investments are written off before the end of their economic life.

So blanket or indiscriminate anti-growth policies would slow down or stop this transformation.

Even just slowing down the transition would be disastrous ecologically. For example controlling global warming caused by the greenhouse effect will require a global improvement in energy efficiency of about 5% per year in every country for the next 30 years. This is 2* time what the Japanese achieved during the height of the OPEC induced energy price rises during the 1970s.

So it is critical that people are discriminating when they are deciding what they are against.

11.3. "Economic growth is neither automatically good nor bad": The implications

----------------------------------------------------------------------------------------------------------

There are a number of important implications arising from the view that economic growth should be neither promoted nor opposed for its own sake.

Existing and proposed economic activity should be supported if it contributes to the achievement of society's environmental and social objectives, and opposed if it detracts from those objectives.

To make judgements about existing economic activity requires an appropriate assessment process. However for new activities or projects it is possible to not only assess proposals but also to take steps to ensure that the proposals are designed from the start to be socially and environmentally valuable . This can be thought of as the proposal generation process, as opposed to the proposal assessment process.

If ecological and resource sustainability are to be objectives for development, proposals must be designed or assessed in the appropriate context. You can't talk about a sustainable product in isolation from its context since it is the environment as a whole that must be sustained. To make such system-level judgements in a practical way, it is necessary to invent standardised frameworks in which it is possible to make judgements. In addition it will be necessary to maintain publicly accessible environmental histories for materials and processes used in production.

It might be thought that an economy in which a range of development options is being actively opposed would be unable to generate full employment, a good standard of living and some hope of qualitative improvement in the future. If socially and environmentally desirable development can be substituted for socially and environmentally inappropriate development, then there should be no reason to fear the adoption of a discriminating approach to economic development. This outcome is likely if a process of transformed market conforming planning is applied to the economy. This process is an adaptation of the concept of market conforming planning which is applied by the Japanese, some European countries and their emulators.

12. The politics of it all

====================

It is sometimes argued that, while it might be theoretically possible to have economic growth that is environmentally sound, it is most unlikely that the measures needed to ensure environmental soundness will be put in place. And so it is better to just oppose economic growth outright.

This argument does not make sense politically since opposition to economic growth as such, and in particular the measures that would be needed to block it generally, are less popular and less defensible than are the measures required to make the economy and society green and socially sound despite any economic growth that might occur.

While nobody would argue that putting the right environmental and social policies in place to achieve a truly sustainable society is easy, it is actually easier than putting in place policies that will prevent all occurrences of economic growth.

Fortunately in this case the (slightly) easier political course is actually the technically and morally correct course too.

13. Summary of key conclusions

===========================

* Economic growth and growth in the use of physical resources are not the same thing.

* Growth in physical resource use, especially exponential growth, cannot go on for long, on an historical time scale, without disastrous environmental effects.

* Global growth in physical resource use must be brought to an end at some point, and in fact there is ample evidence that society has already gone well past the level of resource use that would justify this.

* Economic growth should not be automatically promoted nor should it be automatically opposed.

* Long term economic policies should be framed without reference to overall long term economic growth. Other more specific indicators should be used.

* Economic policies should be chosen on the basis of the specific social and environmental benefits they generate and the competitiveness and meta-stability of the system that they promote (some minor instability in economic systems is inevitable e.g. business cycle fluctuations).

* It is possible that, without actively promoting growth as a policy objective, the pursuit of ecological sustainability and the elimination of poverty could nevertheless give rise to economic growth. This outcome is not a sign of environmental or social policy failure.

1 Although in theory economic growth must reflect quality improvements, this is difficult to do adequately in practice because:

* quality is a notoriously subjective concept. Many of the factors that make up quality for a user cannot be tested objectively because they relate to the 'fit' between the good or service and the needs or wants of the user.

* quality is after all a qualitative (rather than a quantitative) concept. While it is possible to say that product A's quality is higher or lower than product B it is often not possible in reality to say that product A has, say, twice or a third of the quality of product B. Unfortunately it is the latter comparison that is needed in order to estimate growth when qualitative economic changes predominantly.

Given the conservative nature of statistics bodies, these difficulties are more likely to lead to an underestimation of the change in quality than to an overestimation.

So it is easy to underestimate the contribution quality makes to economic growth. If economic growth is used as a indicator for policy purposes then the underestimation of quality could easily lead to a distorted implementation of the policy.

The underestimation of quality growth also could at least partly explain the puzzlingly low growth in productivity in the advanced countries over the last few decades. Quality growth has become a more and more important feature of the economy during this time.

2 Experience with ecodesign has shown that very close attention must be paid to the needs of the customer in order to create the design freedom to find win-win solutions. This close attention to the customer is likely to yield additional benefits unrelated to environmental issues thus boosting overall value adding or productivity.

3 When societies, economies and technologies become complex, most people focus on incremental improvements in the parts of the system. This leaves a vast reservoir of economic and environmental efficiency gains to be made by those who can handle complexity.

4 In a conserver economy tax/subsidy policies would ensure that the relative prices of physical resources rose strongly against labour costs. So in economic downturns, employers would be less inclined to turn to labour shedding as a way of reducing costs. Instead they would be inclined to save costs by using labour to reduce resource consumption.

5 The change in cost structure would arise because of Increased urban land taxation that would be part of a physical containment policy package and the increase of raw material costs relative to labour costs.

6 Through cleaner and leaner production - reducing virgin resource production, improving in-plant resource utilisation, reducing pollution processing costs, reducing public waste disposal costs.

7 Through increased use of just-in-time hiring rather than product ownership.

8 By improving public transport operating on its own right-of-way (eg. rail and sometimes buses and trams), by improving electronic communications where this substitutes for physical movements, and by reducing the use of roads thus making commercial movements faster where they do occur.

9 Through carefully designed higher density and by reducing resource requirements per person.

10 This is a paradoxical opportunity. Exports by the richer elements of poor countries to the rich countries, for example the US, is a tried and true method of kick starting economic development on a large scale with high growth rates in poor countries. However, such a strategy leaves countries very exposed to international trade cycles and to the correction of the unsustainable US trade deficit. Boosting wealth creation among large numbers of the resourceful poor can be a high growth, lower risk strategy in well managed poor countries. Exports to the rich countries would still be needed to pay for the investment capital under this scheme but the scale of exports would be smaller than strategies where income growth arose directly from export revenues.
