This page provides a summary of Oregon’s mandatory greenhouse gas reported data.
Large emitters of greenhouse gases including facilities with air quality permits, fossil fuel suppliers, electric utilities and landfills annually report greenhouse gas emissions to DEQ. The data collected does not represent a comprehensive summary of all of Oregon's greenhouse gas emissions. For example, sources such as smaller commercial facilities and agricultural operations are not reported. Additional information on greenhouse gas reporting applicability and protocols is available on DEQ’s greenhouse gas reporting page
