The petroleum sector, which includes the production, import, processing, transportation, and distribution of crude oil and refined products such as gasoline, heating oil, diesel, propane, and jet fuel, is a significant source of U.S. greenhouse gas (GHG) emissions.

Greenhouse gas (GHG) emissions associated with natural gas make up nearly 18 percent of total U.S. GHG emissions. This report provides an overview of the different point-of-regulation options for covering greenhouse gas emissions from natural gas under a cap-and-trade program.
