CARBON & THE BUILT ENVIRONMENT
Embodied Carbon

California halves its embodied carbon threshold, and the paperwork behind it is changing too

CALGreen's commercial compliance threshold dropped from 100,000 to 50,000 square feet on January 1, 2026, pulling thousands more projects into embodied carbon review just as SB 253's first climate disclosure deadline passed and the EPD standard underneath compliance got its first rewrite in 20 years.
