This sector comprises petroleum refineries and importers and exports of petroleum products and natural gas liquids. These suppliers do not report direct emissions, but instead report the quantity of CO₂ that would be emitted if the fuels and other products they supply each year were combusted. Petroleum refineries also report the volume of all feedstocks entering the refinery.

Emissions associated with these products do not occur at the supplier's facility but instead occur throughout the country, wherever they are used. The full GHG quantity reported by suppliers might not always result in GHG emissions, and the emissions might not take place during that particular reporting year. An example is ethylene, which is a byproduct from petroleum refining that is often used to produce plastics.

The GHG quantities reported by suppliers can be accessed through the suppliers section of FLIGHT. Petroleum refineries also report direct emissions under other applicable subparts. Click here to learn more.
