Seattle's Greenhouse Gas Inventories
The Office of Sustainability & Environment tracks and measures Seattle's greenhouse gas emissions on a regular basis. Called greenhouse gas inventories, these reports identify the source and amount of greenhouse gas production across the city of Seattle, as well as from city operations. Greenhouse gas inventories inform planning and help monitor progress made toward our climate protection goals.
OSE conducts a community greenhouse gas inventory every three to four years.
Municipal Operations Inventory
Also known as a "corporate inventory," this inventory measures emissions from operation of Seattle's municipal buildings and fleets, landfills, employee commutes and air travel, solid waste, and from electricity purchased through contracts to supplement the City's hydropower. Municipal operations inventories are also done every three to four years; our next municipal operations inventory for 2011 data will be completed in 2014.
