Marin County, Calif., Enacts First Low-Carbon Concrete Code in US
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.

I wonder how much carbon dioxide, etc., the factory making powdered concrete with carbon baked out must create to remove the carbon from the concrete. That is, does it cost more carbon into the air to remove carbon from the powdered concrete than is removed from the production of low carbon powdered concrete? If so, then carbon added to the atmosphere by the powdered concrete factory is greater then that which is saved from any carbon removed from the powdered concrete.

The Low-Carbon Concrete Code covers both residential and commercial construction. The standards for industry practices include:
1: Replacing Portland cement with supplementary cementitious materials
2: minimizing the amount of cement in mixes
3: selecting aggregate
4: changing the requirements for how quickly concrete has to cure
