The map contains greenhouse gas (GHG) data reported to Ecology as of April 24, 2017. The reported emissions are preliminary and have not been fully verified by Ecology. This information is subject to change.

Except where noted, emissions are reported in metric tons of carbon dioxide equivalent (CO2e). CO2e is a useful measure for comparing the emissions from various greenhouse gases based upon their global warming potentials.

Organizations that have emissions spread throughout the state instead of at a single location, such as petroleum product producers/importers and natural gas distributors, are not included in this map. See the complete report to view emissions for all Washington organizations that emit at least 10,000 metric tons of carbon dioxide equivalent.

This map shows the air emissions reported by major industrial, commercial, and institutional facilities that have an Air Operating Permit (AOP). Each major facility is represented by an icon that, when clicked, shows the annual tons of pollutants (Carbon Monoxide, Volatile Organic Compounds, Nitrogen Oxides, Ammonia, Coarse Particles, Fine Particles, and Sulfur Dioxide) and greenhouse gases (Carbon Dioxide, Methane, Nitrous Oxide, and Fluorocarbons) emitted into the air. All air pollutant values are from the 2016 Comprehensive Emissions Inventory. All greenhouse gas (GHG) values are from the 2016 GHG Reporting Data. Note that GHG data uses metric tons while AOP data uses US short tons.

The Air Operating Permit (AOP) Regulation Program requires a permit for a facility if it has the potential to annually emit more than 100 US tons per year of any regulated air pollutant. The GHG Reporting Program requires reports from facilities that emit more than 10,000 metric tons (11,023 US tons) per year of CO2-equivalent GHGs. Note that not all AOP sources are required to report GHGs. See the About Tab for links to more information.

The map contains greenhouse gas (GHG) data reported to Ecology as of December 15, 2018. The reported emissions are preliminary and have not been fully verified by Ecology. This information is subject to change.

Certain large facilities and transportation fuel suppliers are required to report their greenhouse gas (GHG) emissions to Ecology beginning with the 2012 emissions year. Owners or operators of the following are required to report:
• Facilities that emit at least 10,000 metric tons of carbon dioxide equivalent (CO2e) of greenhouse gases per year in Washington.
• Suppliers of liquid motor vehicle fuel, special fuel, or aircraft fuel that supply products equivalent to at least 10,000 metric tons of carbon dioxide per year in Washington. These sources are not included on this map because they do not have a specific location.

This dataset does not include all of Washington’s emissions. See the Washington State Greenhouse Gas Emissions Inventory (https://ecology.wa.gov/Research-Data/Scientific-reports/Statewide-greenhouse-gas-inventory) for statewide emissions totals.

Emissions are in units of metric tons of carbon dioxide equivalents using AR4 global warming potentials as specified in WAC 173-441.
