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.
Mandatory reported data is a key source of state level emissions data utilized as an input into Oregon’s greenhouse gas in-boundary inventory which includes emissions across all sectors. For additional information on how Oregon tracks greenhouse gas emissions visit DEQ’s greenhouse gas inventory page.

Sources and emissions feasibly covered by a cap-and-trade program

In 2016 Oregon Legislature directed DEQ to study considerations for implementing a market-based greenhouse gas reduction program in Oregon. As part of the study DEQ compiled a list of companies and facilities, based on 2014 mandatory reported data, which could feasibly be regulated entities under a cap-and trade program. DEQ has updated the list of potentially regulated entities found in Appendix 1 of the Considerations for Designing a Cap-and-Trade Program document based on 2016 greenhouse gas emissions data.
