The Environmental Protection Agency (EPA) is looking at ways to expand its greenhouse gas registry, which was finalized in October. The EPA is attempting to develop new rules that would bring oil and gas operations, carbon sequestration sites, and fluorinated GHG sources into the registry. They are also holding discussions on how to create a new rule to make it easier to calculate emissions for corporations. The EPA has already submitted to the White House Office of Management & Budget multiple new reporting rules for different sectors, including oil and gas facilities and carbon sequestration sites.

The EPA is currently involved in litigation over the greenhouse gas registry with both industry and environmental groups. Industry groups are challenging provisions related to certain deadlines and the legality of some of the reporting requirements, while environmental groups are challenging the rule because they believe it does not cover enough sectors.
