Greenhouse Gas Reporting Protocols

Oregon rules require certain facilities to report their annual greenhouse gas emissions to DEQ using DEQ-approved protocols. The reporting program is providing us a better understanding of Oregon's emissions, contributing to a comprehensive inventory of Oregon's emissions, and improving our ability to track progress toward meeting emission reduction goals established by the state legislature.

Click on each facility type below to learn about who needs to report within each facility category, reporting deadlines and the methodologies facilities must use to calculate and report emissions.

Facilities required to report greenhouse gas emissions to DEQ:

Facilities emitting 2,500 metric tons or more of carbon dioxide equivalent during a year, including

• Air quality permit holders (in Oregon's ACDP and Title V programs)
• Landfills
• Wastewater treatment facilities

Suppliers of fuels and electricity, including

• Gasoline, diesel and aircraft fuel distributors
• Propane wholesalers
• Natural gas suppliers
• Investor owned utilities and electricity service suppliers
• Consumer-owned utilities

If you have questions, email the greenhouse gas program or call Colin McConnaha at 503-229-5094 (toll-free in Oregon 800-452-4011).

Relationship to Federal Greenhouse Gas Reporting Requirements

40 CFR. Part 98 requires large facilities and suppliers of greenhouse gas emissions in the United States to report those emissions to EPA. EPA's reporting program applies to facilities emitting 25,000 metric tons or more of carbon dioxide equivalent during a year.

Facilities required to report greenhouse gas emissions to EPA that are also subject to Oregon's reporting requirements must report greenhouse gas emissions to DEQ. DEQ has taken measures to simplify reporting for facilities subject to both the Oregon and federal requirements and avoid duplicative reporting wherever possible. See DEQ-approved reporting protocols (above) for each facility category for more information.
