Oregon’s sector-based inventory measures human-caused greenhouse gas emissions produced within Oregon by economic sector. It also includes the emissions associated with the electricity used in Oregon regardless of where that electricity is generated. The
Oregon Global Warming Commission utilizes the sector-based inventory to track progress toward Oregon’s emission reduction goals.
DEQ also compiles a
consumption-based inventory that measures greenhouse gas emissions produced around the world due to the state’s consumption of goods and services. Oregon contributes to climate change in many different ways, and the use of these two inventories provides a more complete understanding of that contribution.
Greenhouse gas emissions from 1990-2019
Emissions from transportation and electricity use are Oregon's largest sources of greenhouse gas emissions.
Sector based data
It is good practice to update emission estimations when improved methods or data become available. For this reason, published data sets may vary from year to year.
Preliminary emissions data
To provide the most current emissions estimates possible, DEQ develops preliminary greenhouse gas estimates based on reported data that is often available up to a year earlier than data from EPA’s State Inventory Tool. When an updated version of the State Inventory Tool becomes available, DEQ updates and finalizes preliminary emission estimates. DEQ is committed to updating the inventory on an annual basis.
