The U.S. Environmental Protection Agency (EPA) has formally withdrawn cybersecurity rules it promulgated in March requiring that states report cybersecurity threats to their public water systems (PWS). The reversal comes in the wake of lawsuits filed in the Eighth Circuit in July by Missouri, Arkansas, and Iowa (the states), along with intervenors American Water Works Association and National Rural Water Association (the water associations). As a result of the withdrawal, the states and water associations filed to dismiss their suits.

On October 7, 2023, California Governor Newsom signed two landmark bills into law, Senate Bill (SB) 253 and SB-261, imposing new requirements on large companies doing business in California to publicly report their annual greenhouse gas (GHG) emissions and climate-related risks. These laws apply to both publicly traded and privately held companies, exceeding the scope of the climate disclosure rule proposed by the U.S. Securities and Exchange Commission (SEC) in March 2022.
