On October 7, 2023, California Governor Gavin Newsom signed into law two sweeping climate disclosure bills, Senate Bill 253 (“SB 253”), the Climate Corporate Data Accountability Act, and Senate Bill 261 (“SB 261”), the Climate-Related Risk Act. Taken together, SB 253 and SB 261 overlap the U.S. Securities and Exchange Commission’s proposed climate disclosure rule (the “SEC Proposed Rule”), and expand upon it in several significant ways. The SEC Proposed Rule addresses both greenhouse gas (“GHG”) emissions and climate risk, while the California measures separate the two, with SB 253 addressing GHG emissions, and SB 261 addressing climate risk.
