Sustainable Washington

3.3 Project Example #1

Action: Greenhouse Gas (GHG) Inventory
Where: Washougal, WA
More Info:,, and

In 2008 and 2009 Washougal, WA, participated in the London-based Carbon Disclosure Project, joining 21 US cities such as Denver and New York in assessing Greenhouse Gas (GHG) Emissions from city operations. The assessment was conducted using CACP software as developed by ICLEI, an international association advancing sustainability at the local level with over 1,000 member cities. Of the 23 ICLEI members in Washington State, at least 16 are conducting or have completed inventories of their GHG emissions. The CACP software was recently updated in 2009, providing a uniform standard of GHG reporting that aligns with the Climate Registry (see link above); other GHG reporting tools and organizations are available and also warrant investigating. A June 2009 Sustainability newsletter within the city notes that the GHG inventory will help the city to better develop sustainability policies and monitor its use of natural resources.

Conducting a GHG inventory provides insight not only into emissions levels but also energy consumption itself, as detailed energy data is required for reporting. Washougal will take the next steps of setting reduction targets and develop reduction strategies over the summer of 2009. In the meantime, the city is noting that it may enjoy some economic advantages from GHG reporting, including energy efficiency savings, and commercial advantages for businesses seeking “greener” cities in which to locate their headquarters.

The 16 Washington cities known for conducting or having completed GHG inventories are: Bellevue, Bellingham, Edmonds, Everett, Kirkland, Lake Forest Park, Langley, Lynnwood, Redmond, Renton, Seattle, Shoreline, Spokane, Tacoma, Vancouver, and Washougal.
