Corporations and industries can expect greater scrutiny of their carbon footprints under changes U.S. EPA proposed to its mandatory greenhouse gas registry yesterday.

Beginning this year, companies must detail emissions from about 10,000 facilities representing some 85 percent of the nation’s total carbon output, according to the greenhouse gas reporting regulation EPA completed in September.

Under the new proposal, these individual emitters — from power plants and oil refiners to large manufacturers — would have to include their U.S. parent company and an industry classification code in their annual reports. The change will inform sectorwide air pollution and climate strategies the agency is evaluating, the proposal notes.
