Washington State Greenhouse Gas Emissions Inventory, 1990-2010

The state’s greenhouse gas inventory estimates Washington’s anthropogenic GHG emissions for the period from 1990 to 2010. GHG emission estimates were developed using a set of generally-accepted principles and guidelines for state GHG emission estimates, with adjustments for Washington-specific data and context, as appropriate.

The current inventory was published in December, 2012, and updated in September 2013. The Departments of Ecology will update this greenhouse gas inventory for the state every two years as required by state law. The next inventory will be completed in December 2014.
