The Oregon Global Warming Commission submits a report to the Oregon Legislature every two years, publishing data on current greenhouse gas emissions, trends, and steps we need to take to reduce emissions.
Greenhouse Gas Emissions in Oregon: Forecast & Goals
The chart above shows emissions to date, the trajectory we need to reach our reduction goals, and our likely trajectory based on current trends and policies.
Greenhouse Gas Emissions by Sector
The graph above shows that transportation is still the greatest contributor to greenhouse gas emissions in Oregon, followed by the residential and commercial sectors.
Consumption-Based Inventory
Oregon also estimates its contribution to global greenhouse gas emissions using a consumption-based inventory, which estimates the global emissions resulting from consumption of goods and services (including energy) by Oregon consumers. Consumption-based emissions are calculated across the life cycle of the items.
Between 2005 and 2015, vehicle use, production of food, and use of appliances (primarily heating and cooling) contribute the most to emissions. Vehicles and parts represent about 20 percent of Oregon’s consumption-based emissions.
