The Department of General Services (DGS) implements laws, also called statutes, passed by the California Legislature and signed by the governor.
The Buy Clean California Act was introduced as Assembly Bill (AB) 262 and signed into law on October 15, 2017. It targets the embedded carbon emissions of certain construction materials used in public works projects. AB 262 requires that these materials have a Global Warming Potential (GWP) that falls below a limit set by DGS. Eligible materials include: structural steel (hot-rolled sections, hollow structural sections, and plate), carbon steel rebar, flat glass, and mineral wool board insulation.
The key dates are:
- January 1, 2019 – EPDs will be requested by the state.
- January 1, 2020 – EPDs will be required by the state.
- January 1, 2021 – DGS publishes the maximum acceptable GWP for eligible materials.
- July 1, 2021 – EPDs will be required and used to gauge GWP compliance of eligible materials.
The current legislation can be found under Public Contract Code § 3500-3505.
Reference Product Category Rules (PCRs) for eligible materials are posted in the resources tab.
