The Carbon Leadership Forum: Who We Are
The Carbon Leadership Forum propels knowledge, collaboration and action to radically reduce the embodied carbon in building materials and construction
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.
Our Vision
We envision a transformed, decarbonized building industry – better buildings for a better planet.
Our Mission
Our mission is to eliminate embodied carbon in buildings and infrastructure by inspiring innovation through collective action to create a just and thriving future.
Our Values
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.

Megan Kalsman
Policy Researcher
Megan Kalsman is a Policy Researcher with the Carbon Leadership Forum at the University of Washington. She specializes in advancing the procurement of low-carbon materials and informs the development and implementation of cross-sectoral climate policies targeting embodied carbon.
Before joining the CLF, Megan completed her Master of Science degree at Lund University in Sweden in Environmental Management and Policy with the International Institute for Industrial Environmental Economics. She published her thesis project in 2021, on the intersection of gender equality with different environmental issues like climate change, biodiversity, and chemicals on an international policy scale.
Prior to studying in Sweden, Megan coordinated environmental policies and programs for local government agencies in California with a focus on toxic chemical reduction and pollution prevention. She helped in developing the first in the nation ban on toxic flame retardant chemicals in San Francisco. This served as a model policy for the State of California and other states in the U.S. passing similar policies. Her undergraduate degree was in Environmental Studies at San Francisco State University with a minor in Urban Planning and the Built Environment.
Megan’s work at the CLF combines her environmental research experience and policy design background. She strives to frame her work with an intersectional lens each day – protecting the health of people and the environment in an equitable way. At the CLF, Megan enjoys interacting with a variety of stakeholders around embodied carbon policies and ultimately working together towards a more sustainable and just future.

Brook Waldman
Researcher
Brook is a research engineer at the Carbon Leadership Forum, where he investigates the life cycle of building materials — their manufacture, use, and end-of-life — and the environmental impacts that accompany those processes. He also studies and aims to improve the methodologies and data behind the measurement and communication of those environmental impacts. At the CLF, he has been particularly involved in supporting the EC3 tool and developing the CLF Material Baselines.
Previously, Brook studied architecture at the University of Oregon, where he focused on lifecycle assessment (LCA) research of high-performance buildings and construction materials, and worked in architectural practice in Seattle. He was also an educator: he taught 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 led youth wilderness trips.
Besides working at the CLF, Brook volunteers as a math tutor for his local alternative high school and as a sorter at his community’s foam and plastics recycling events. He has a life-long fascination with making new useful stuff from old landfill-bound stuff (like furniture-making with salvaged wood and welding for a biodiesel cooperative). And he maintains a small building-LCA-focused consulting company.
