On Nov. 19, the five-person Marin County, Calif., board of supervisors unanimously approved the nation’s first low-carbon concrete code that applies to both public and private construction (ENR 11/4-11 p. 24). The Bay Area Low-Carbon Concrete Building Code, which limits embodied carbon content of both plain and reinforced concrete, goes into effect Jan. 1. Other Bay Area jurisdictions, which had input into the code’s development, are likely to adopt the code, which also is expected to serve as a template for low-EC concrete codes nationwide.
