2008 King County Community Greenhouse Gas Emissions Inventory: “Geographic Plus” Methodology

This 2011 report by the Stockholm Environment Institute estimates King County, Washington's greenhouse gas emissions for 2008 using a 'geographic plus' methodology, covering sources such as transportation, buildings, industry, and waste. Total emissions reached approximately 23.4 million metric tons of CO2 equivalent in 2008, a 5% increase from 2003, with transportation accounting for roughly half of all emissions. The findings were used by King County and its partners to identify major emission sources and develop strategies to meet community greenhouse gas reduction goals.
