Greenhouse Gas Reporting for Suppliers of Liquid Motor Vehicle Fuel, Special Fuel, or Aircraft Fuel Sold in Washington

Reporting Requirements

Certain suppliers or importers of greenhouse gas (GHG) emissions will need to report the calendar year carbon dioxide (CO2) emissions associated with complete combustion of oxidation of their products sold in Washington. Starting as early as 2009 emissions reported in 2010, you must report if you meet both of the following conditions:

AND

The following table lists the emissions factors needed to calculate the emissions associated with the complete combustion or oxidation of fuels sold in Washington. It also lists approximate fuel volumes that will trigger the mandatory reporting threshold. Any of the listed values are enough to require reporting. If you supply multiple fuels, then add the emissions associated with the fuels before applying the threshold.

Fuel Type Emissions Factor
(kg CO2 per gallon)*
Approximate Fuel Sold in WA to Meet 10,000 MT CO2 Threshold
(in Gallons per Year)
Gasoline 8.960 1,100,000
Ethanol 5.767 1,700,000
Diesel 10.23 970,000
Biodiesel 9.421 1,000,000
Jet Fuel 9.750 1,000,000
Aviation Gasoline 8.310 1,200,000

Introductory Meeting For Fuel Suppliers

NOTE: This meeting focuses on reporting greenhouse gas emissions from fuel suppliers. Emissions from facilities and other sources will not be covdered.

On June 8, 2010, Ecology will hold an introductory meeting specifically for fuel suppliers who meet the 10,000 metric ton threshold. The meeting will discuss:

The fuel supplier introductory meeting will be held in person or by webinar:
