The Environmental Protection Agency (EPA) this week proposed the first comprehensive national system for reporting emissions of carbon dioxide and other greenhouse gases produced by “major sources” in the U.S. According to EPA, about 13,000 facilities, accounting for 85-90% of greenhouse gases emitted in the U.S. would be covered.

The proposal would require reports by refineries, automobile makers, power and ethanol plants, coal mines, and large manure ponds on farms that emit greenhouse gas emissions equal to or greater than a “threshold of 25,000 metric tons/year.” The proposed rule will be open for public comment for 60 days.
