Mill Valley adds carbon-free concrete to city code

Mill Valley is adding a carbon-free concrete requirement as it fine-tunes its green building code.

“Tonight the city of Mill Valley took bold climate action,” Mayor Max Perrey said after the City Council backed several updates on Tuesday.

“Decarbonizing our built environment is imperative to addressing climate change, ensuring clean air and protecting human health and our environment,” said Perrey, who advocated for the carbon-free cement on behalf of the Sierra Club before he was elected to local office.
