Who We Are
The Carbon Leadership Forum is accelerating the transformation of the building sector to radically reduce the embodied carbon in building materials and construction through collective action.
We pioneer research, create resources, foster cross-collaboration, and incubate member-led initiatives to bring embodied carbon emissions of buildings down to zero.
We are architects, engineers, contractors, material suppliers, building owners, and policymakers who care about the future and are taking bold steps to decarbonize the built environment, with a keen focus on eliminating embodied carbon from buildings and infrastructure.
We envision a transformed, decarbonized building industry – better buildings for a better planet.
Our mission is to eliminate embodied carbon in buildings and infrastructure by inspiring innovation and spurring change through collective action.
Determination – We are steadfast in our efforts to eliminate embodied carbon in building materials and construction.
Inclusion and Collective Action – We welcome architects, engineers, contractors, material suppliers, building owners, policymakers and associations and foster cross-collaboration to enable a more informed community and spur accelerated outcomes.
Empowerment – We encourage, foster and support members to become champions and move forward their ideas.
Integrity – We ground our work in science and data to understand the full complexity of issues and develop practical solutions.
Transparency – We foster a culture of openness and honesty. We freely share knowledge and resources to advance the field.
How We Do It
Recognizing that buildings account for nearly half of global CO2 emissions, the Carbon Leadership Forum, a non-profit organization at the University of Washington, is dedicated to accelerating the transformation of the building sector to radically reduce the embodied carbon in building materials and construction through collective action.
The Carbon Leadership Forum propels knowledge through its embodied carbon research and resources, collaboration through its robust network of architects, engineers, contractors, material suppliers, building owners, policymakers and associations, and action by supporting and empowering its members to advance new ideas and approaches through impactful initiatives.
We investigate the pathways for maximizing carbon reductions and lead collaborative research with material experts, NGOs, industry partners and policymakers.
We accelerate learning by crowdsourcing and disseminating knowledge that empowers our members.
We bring together architects, engineers, contractors, material suppliers, building owners, policymakers and associations, through environments designed to connect inspired advocates and spark unprecedented collaboration.

Rocky Mountain Institute
Victor Olgyay, AIA is a bioclimatic architect living in Boulder, Colorado. In 1978 he designed his first passive solar house, and has since worked as an architect, writer, professor, researcher, daylighting designer, and environmental consultant. Since 2005, he has been a principal with Rocky Mountain Institute leading the Institute’s Buildings Practice to encourage widespread adoption of deeply efficient building design and comprehensive building energy retrofits.
From 1993 to 2000 Victor was an Associate Professor and Director of Research at the University of Hawaii School of Architecture. He was appointed Chairman of the AIA Honolulu Energy and Environment Committee 1995–2000, and in 1998 he was named a Dana Fellow of the Joslyn Castle Institute for Sustainable Communities. He has served on the Board of Directors for the American Solar Energy Society, and is currently on the University of Colorado Design Review Board, and the GSA Green Building Advisory Committee.
Buildings must support human and ecological needs. Victor’s research on ecosystem services as criteria for green building assessment resulted in the “Green Footstep” building tool, demonstrating a lifecycle approach to the reduction of carbon, water, and ecological footprints. His recent work demonstrates how restorative buildings and communities (that generate more resources than they consume) can be profitable investments and act as positive assets, enhancing electrical and utility system infrastructures.
