On April 25, 2024, the Environmental Protection Agency (EPA) issued a final rule making various changes to its Greenhouse Gas Reporting Rule regulations. Among other changes, the final rule updates the global warming potentials and emissions factors that are used in calculating emissions, and modifies emissions calculation methodologies. The final rule also establishes new greenhouse gas monitoring and reporting requirements for five source categories: (1) coke calcining, (2) ceramics manufacturing, (3) calcium carbide production, (4) caprolactam, glyoxal and glyoxylic acid production, and (5) facilities conducting geologic sequestration of carbon dioxide with enhanced oil recovery.
