This summit marks five years since the BSA held the Embodied Carbon in Buildings Conference which led to the development of the EC 101 Series and the creation of the CLF Boston / Northeast Hub. In the past five years, great strides have been made through advocacy, research, education, outreach, and implementation - nationally and regionally. There have been advances on many fronts including policy, concrete, biogenic materials, adaptive reuse and more case studies. The goal of this summit is to come together to learn from each other, provide resources to the broader AEC community, and to advance our collective efforts.
