greenhouse gas emissions directly from activities like driving cars and heating
homes. We also indirectly contribute to greenhouse gas emissions when we
purchase electricity, goods or food manufactured in other states or countries. These
emissions are contributing to global climate
DEQ evaluates statewide
greenhouse gas emissions in two ways:
Sector-based inventory: Emissions produced in Oregon from its
transportation, residential, commercial, industrial and agriculture sectors,
including electricity produced elsewhere but used in state.
- Consumption-based inventory: Emissions produced around the world due to Oregon’s
consumption of energy, goods and services. Over half of Oregon’s consumption-based
emissions occur in other states or nations and are not included in the sector-based
DEQ publishes a comprehensive report every five years that evaluates Oregon’s greenhouse gas emissions with data from the sector-based and consumption-based inventories.
Oregon’s sector-based emissions are 10 percent above 1990 levels. Consumption-based emissions are 42 percent above 1990 levels.
Oregon has goals to reduce emissions 10 percent below 1990 levels by 2020 and 75 percent by 2050. The Oregon Global Warming Commission uses DEQ data to track trends in greenhouse gas emissions and recommend strategies for meeting these goals.
