Who We Are
The Carbon Leadership Forum accelerates 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 through collective action to create a just and thriving future.
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.

Before joining the CLF, Megan completed her Master of Science degree at Lund University in Sweden in Environmental Management and Policy. She has experience managing environmental programs in local governments, businesses, and non-profit organizations, with an emphasis on climate justice and stakeholder engagement.
It started with teaching high school math (how can we follow the numbers?) and environmental studies (what is our human relationship to the earth’s material and energy flows?), and a fascination with making new useful stuff from old landfill-bound stuff. Next were architecture school and practice, and lifecycle assessment (LCA) research of high performance buildings and construction materials. Now Brook supports the CLF’s mission through research and analysis of building materials — their manufacture and use, their environmental impacts, and the methodologies behind measuring and communicating those impacts.
As an environmental scientist aspiring to pursue her PhD in forest ecology, Christina’s strengths lie in data collection/analysis and creative, multidisciplinary problem-solving. She recently graduated from Western Washington University with her B.S. in Environmental Science and is pursuing her Master of Science from the University of Washington’s School of Environmental and Forest Sciences at the CINTAFOR lab. Her thesis will explore different ways to recycle mass timber products and the implications this has on carbon storage in wood buildings.
Monica Huang is a research engineer for the Carbon Leadership Forum at the University of Washington. Her background is in civil and structural engineering and currently works on research on environmental life cycle assessment (LCA).
