Program Overview and History
In 2018, the County of Marin was granted funds from the Bay Area Air Quality Management District (BAAQMD)'s Climate Protection Grant Program. This project aims to reduce embodied emissions in the built environment by creating local specifications and model policies for low embodied-carbon concrete, developed through a robust regional stakeholder engagement process. The County of Marin leads the project, working in close partnership with StopWaste (Alameda County), Bruce King, Arup, and the Carbon Leadership Forum. The project proposal submitted to and funded by BAAQMD was supported by the City and County of San Francisco, County of Alameda, City of Berkeley, USGBC, and over 30 building industry companies and organizations that work in the Bay Area.

Finally, circumstances compel the project team, with support of the Concrete Working Group, to dedicate this body of work to Professor Mark Aschheim. Mark passed away before this code was completed, but was an active participant early in the project, and made many important contributions to it through his illness. He was widely known in the concrete industry for his contributions to seismic design, and widely known more broadly for his many contributions to climate-friendly construction in California, in Haiti, and all over the world. He was a good friend to many of us, and a teacher to many more. We offer our regards to his family, and this dedication to his memory.
