Carbon Leadership Forum (CLF) Northeast U.S. & Canada Embodied Carbon Policy Case Studies

• Description: "Policies that address embodied carbon are being proposed and adopted at all levels of government- federal, state and local- at a rapidly accelerating pace. This report highlights nine policies in the Northeast region of the United States and Canada as examples of successfully passed policies targeting embodied carbon reporting and reduction. Each case study explores the policy’s development process, the stakeholders engaged, any challenges faced, and keys to successful adoption."
