Transportation is becoming increasingly more vital in our society; we use it everyday to get to school and work, to run errands, and to see people we love. With a rise in demand for cars, trains, buses, and planes comes an increase in emissions floating from our vehicles into our air. Making small and simple changes to how you get around each day can end up causing a big environmental impact!

What You Can Do:

Public Transportation:

  • All CU students receive a free RTD College Pass to use during the school year via the Environmental Center. The pass can even take you as far as Union Station and DIA! 

  • Ride the CU Ski Bus to popular ski resorts on the weekends to save money on gas, relieve the stress of driving to and from the slopes, and decrease carbon emissions!


  • While public transportation still uses energy to get you where you need to go, biking does not utilize any at all! Plus, it will get you in shape. Choosing to bike to work or class rather than drive can save over 3,000 pounds of greenhouse gas emissions each year, and the cost of maintaining a bike is twenty times less than that of a car.

  • With over 300 miles of bikeway, including on-street bike lanes, designated bike routes, and paved shoulders, Boulder is great for cyclists.

  • The CU Bike Station, which has two locations across campus, can teach you how to maintain and care for your bike. If you do not have a bike of your own, you can rent one from the station: either short term (two days) or long term (one semester).

  • Join Boulder B-Cycle to use any of their red bikes throughout Boulder!


  • Just like biking, walking to class or work wastes no energy and is great for your health. Boulder has been designated as a Gold-Level Friendly Walking Community due to its commitment to the accessibility and safety of its pedestrians. 


  • If you have to drive to get where you’re going, there are simple ways to make sure that your car is more efficient. Obeying the speed limit, making sure your tires are inflated properly, removing excess weight from your trunk, and turning your engine off when it is parked can make your time on the road more sustainable. 

Green Travel:

  • Traveling can broaden your worldview and open your eyes to new experiences, but it can also have a large environmental cost. A round-trip flight from New York to San Francisco creates a warming effect equivalent to 2 tons of carbon dioxide per person-- one tenth of all of the carbon emissions a person produces in a year. Lessen your footprint by taking non-stop flights, as the majority of emissions are emitted during takeoff and landing.
  • Support local businesses, such as hotels, restaurants, and shops, instead of large tourist corporations when traveling. Instead of purchasing a keychain or snowglobe from a tourist shop, consider purchasing a unique souvenir from a local artisan made from local resources.
  • Before you book a hotel or hostel, make sure that their environmental values align with yours!
