California has taken a significant step in aligning its procurement expenditures with its vanguard climate change policy. On October 15, 2017, Governor Jerry Brown signed A.B. 262, the Buy Clean California Act (Chapter 816, Statutes of 2017). Beginning in 2019, the state’s Department of General Services (DGS) is to establish maximum carbon emission levels for “eligible building materials,” consisting of carbon steel rebar, flat glass, mineral wool board insulation and structural steel. At that time, state agencies may only award contracts to bidders certifying that their sources of these materials meet the standard.
This legislation was supported by manufacturers that have invested heavily in emission reduction processes, along with labor unions and environmental organizations. The Brazilian firm Gerdau Steel, having made expensive upgrades to the only California steel mill and its other facilities, greeted the signing by saying the act will “level the playing field” against sources that have greater emissions from manufacturing and transportation.
