The California Building Standards Commission will be considering a range of CalGreen code  
amendments during the 2022 Intervening Code Cycles. These will include a proposal to  
adopted a new set of embodied carbon requirements for buildings over 50,000 sq. ft.

This code proposal will go before the CALGreen Code Advisory Committee on **February 8-10** ,  
2023. Following the CAC meetings, if the proposal recommended for adoption, then it will undergo public review and comment starting in April.

Thank you Megan! Could you give a little more detail on which/where documents we should look at/comment on? I tried to look around, but was confused. Thank!

When you navigate to this webpage: [CAC Mtgs](https://www.dgs.ca.gov/BSC/Rulemaking/2022-Intervening-Cycle/2022-CAC-Mtgs)

Click the expand button titled **Green February 8-10, 2023**

Under the heading **BSC 04/22 — Amend the 2022 edition of the California Green Building Standards Code, Part 11, Title 24** the language can be found in the linked items.

Summary of the proposal:

Nonresidential new construction projects over 50,000 square feet will be required to comply with  
one of three pathways intended to reduce embodied carbon by approximately 10% compared to  
business-as-usual. These large projects need only comply with one of the following:  
● Reuse 45% of an existing building  
● Complete a whole building lifecycle analysis (WBLCA) demonstrating 10% lower than a  
baseline project design  
● Obtain environmental product declarations (EPDs) for five high-impact materials that are  
on average lower than a specified threshold of global warming potential

Hope this helps!
