Enterprise Building Greenhouse Gas (GHG) Emissions (2019-2023)
GHG emissions from state buildings mostly come from energy use. Another source is chemicals used in heating and cooling systems (HVAC), but they are not included in this report.
Like energy use, GHG emissions can change when agencies add or remove buildings, improve energy efficiency, adjust operations, or changing weather patterns.
GHG emissions are grouped into two main “Scopes”:
- Scope 1: Fuels burned onsite, like natural gas used to heat a building.
- Scope 2: Electricity purchased from a utility where the utility uses fuel to create electricity.
In Oregon, utilities are increasing electricity from renewable sources like wind and solar. Hydroelectric dams also supply a large share of Oregon's electricity.
Agency Building Greenhouse Gas Emissions (2019-2023)
Agencies can reduce building-related GHG emissions by:
- Using more efficient HVAC systems.
- Sustaining buildings efficiency.
- Installing renewable energy, like solar panels.
Utilities also offer “green energy” programs. These allow agencies to buy credits to offset emissions from electricity created by fossil fuels. However, these programs are usually a last step after onsite energy efficiency and renewable energy enhancements have been made.
Note: Blank years in the data mean the agency did not report energy use that year. Green energy credits bought by agencies are not included in this chart.
