Climate Lawsuits and the Toxic Substances Control Act

In November, a civil suit was filed to compel the EPA to use the Toxic Substances Control Act (TSCA) to regulate greenhouse gas emissions. The suit argues that CO2 and methane, the main greenhouse gases, pose an unreasonable risk to health and the environment and should be regulated under TSCA. The EPA's rejection of the petition is criticized for not acknowledging the magnitude of the risk and relying on other measures, such as the Inflation Reduction Act, that fall short of addressing the problem effectively. The lawsuit seeks a court determination that greenhouse gases present an unreasonable risk and urges the EPA to open a rulemaking process to eliminate this risk.
