Greenhouse Gas Emissions
Greenhouse gas emissions are a major cause of climate change. Comprehensive monitoring helps to reduce emissions by guiding changes in production practices, materials use, and purchased energy services.
Greenhouse Gas Emissions
In 2009, the State Agency Climate Leadership Act took effect requiring state agencies to lead by example in reducing their Green House Gas (GHG) emissions to:
- 15 percent below 2005 levels by 2020
- 36 percent below 2005 levels by 2035
- 57.5 percent below 2005 levels by 2050 or 70 percent below the expected state government emissions that year, whichever amount is greater
|Greenhouse Gas Emissions 2011 |
Totals in Metric Tons of CO2e
|Scope 1: Direct||2308.3|
|Scope 2: Indirect||3651.6|
|Scope 3: Purchased Electricity||3651.6|
|Scope 4: Employee Business Travel & Commuting||2904.6|
The law directs agencies to annually quantify their GHG emissions, estimate future emissions, develop a strategy to meet the reduction targets and track actions taken to reduce emissions. Gov. Chris Gregoire challenged Ecology to reduce our agency’s carbon emissions and serve as a model for what other state agencies can do.
We will share what we learn with other state agencies, businesses, and homeowners so they too can be part of the solution. Many of these actions will not be short-term fixes. But all will be a part of a new way of doing business that reduces emissions, saves money and moves us toward a more sustainable business model.

Strategies for Reducing Greenhouse Gas Emissions: June, 2011
Ecology is committed to reducing its own greenhouse gas (GHG) emissions. By implementing new business practices, operational improvements and energy and fuel efficiency projects, we can provide a blueprint for state government and the general public to save energy, money and reduce GHG emissions. Ecology has projects underway that will reduce its emissions by an additional 1,925 MTCO2e by 2020. This is well beyond the 753 MTCO2e reduction needed to meet the agency’s 2020 emissions target and will achieve 93 percent of the reductions needed to meet its 2035 target.
Over half of Ecology’s planned emissions reductions are from building energy efficiency improvements. Energy efficiency projects are currently being implemented through an Energy Services Performance Contract. In addition, Ecology plans to reduce its emissions through improvements in fleet fuel efficiency, IT energy efficiency and employee behavior change.
Ecology is aggressively implementing the following:
- Best practices with no- to low-cost, such as education, incentives, policies and standards that would change or adjust employees’ behaviors (e.g., minimize idling, turning off computers).
- Technological changes to reduce energy consumption from buildings and equipment.
- Capital improvements and equipment upgrades that pay for themselves through energy savings and operational costs.
- All policies adopted by the Legislature (i.e., purchase of biodiesel, green buildings, vehicle efficiencies, etc).
