We engage in community partnerships to advance social and environmental justice in the transition from fossil fuels to a renewable-based economy and in response to climate change. We work to support leadership of underrepresented groups to foster more equitable energy, climate and employment practices and policies, and to produce community-relevant research. 


The JTC was founded in 2016 by Manuela Sifuentes, Michelle Gabriellof-Parish, Phaedra C. Pezzullo and David Ciplet. The impetus for the JTC occured when Manuela and Michelle voiced concerns that the City of Boulder's planning process lacked a focus on equity and justice. Shortly after, the four co-founders organized the JTC to encourage and support the City of Boulder to advance social justice and inclusivity in its climate and energy planning. From 2017 until 2019, Magnolia Landa-Posas worked as the JTC's Community Engagement Manager. 

In 2020, Manuela and Michelle accepted jobs elsewhere, continuing the important work needed for a Just Transition. Manuela became a Language Access Program Manager with the City of Boulder. In 2020, Manuela helped to launch this important resource. Michelle works remotely for Movement Strategy Center, the NGO Boulder County hired in 2019 as facilitators and consultants on a just transition, along with the JTC. David and Phaedra remain on faculty at CU Boulder, and as Co-Directors of the JTC.
