(Consumption Basis  for Electricity)
Inventory Notes:
Data generated from the EPA State Inventory Tool (SIT) except for electricity consumption (ODOE) and waste/materials (ODEQ).   Zeroes in some columns may mask emissions that are in the hundreds of metric tons and don't show up above.
An emerging consensus is for greenhouse gas inventories to attribute energy emissions to the jurisdiction in which the energy is consumed.  The Western Regional Air Partnership and the Western Climate Initiative use this convention. Using emissions
attributable to in-state power generation (rather than power consumption) is done by the federal government for national data and US DOE state-level reporting.  For purposes of comparison data using this "production based" method are below:
Gross Production Emissions

Remove Electricity Consumption Total	(16.698)	(16.960)	(16.671)	(20.731)	(20.915)	(21.267)	(21.945)	(22.139)	(20.967)	(22.112)	(23.407)	(22.830)	(21.434)	(21.818)	(21.538)	(23.850)
Gross Emissions, Production Basis	40.619	44.254	45.191	45.881	47.445	45.269	47.350	47.043	51.613	53.269	53.204	52.951	51.276	51.580	53.968	54.146
Note:  US EPA data for in-state power generation emissions (used in the SIT and thus the above production based data) varies from US DOE in-state generation emissions data.  Inventories using the US DOE data therefore will not match these data.
