Sector Trends

Overall, communitywide emissions have been increasing since the 2015 baseline. Increases in electricity consumption and growth in solid waste generation have pushed emissions upward, while improvements in vehicle fuel economy and unchanged driving distances softened the extent of those increases.

Buildings & Energy; 10% increase from 2015  

Emissions from buildings and facilities account for approximately 57% of total emissions. In 2018, emissions totaled 1,804,346 MTCO2e. Emissions from this sector come from fossil fuel combustion related to heating, cooling, and outdoor lighting. Learn More


Transportation & Land Use; 2% increase from 2015

Transportation related emissions is the second largest source of emissions (32%). In 2018, emissions from transportation sources totaled 1,015,867 MTCO2e and included emissions associated with passenger cars and trucks and off-road vehicles such as for construction, agriculture, lawn/gardening, and recreational equipment. Learn More


Solid Waste; 17% increase from 2015

In 2018, emissions from solid waste totaled 139,322 MTCO2e contributing to 4% of Thurston’s total emissions. The major source of solid waste emissions from methane leakage. This leakage from landfills totals more than 132,000 MTCO2e. Other solid waste emissions originated from processing and transportation of solid waste. Learn More

Wastewater Treatment; 1% increase from 2015

Wastewater treatment only makes up a small fraction of Thurston’s total emissions (1%). In 2018, emissions from wastewater treatment totaled 16,980 MTCO2e. Personal septic systems were responsible for 97% of wastewater emissions. Learn More


Agriculture & Forests; <1% decrease from 2015

Emissions from agriculture and forests contribute only a small portion of total emissions (2%). In 2018, emissions related to land management, livestock, and manure totaled 76,762 MTCO2e with livestock and manure management contributing to nearly 99% of all agriculture related emissions. Learn More

Other Sources; 12% increase from 2015

Emissions from other sources contribute a minor portion of total emissions (4%). Emissions from HFCs—a common refrigerant used in refrigeration and air conditioning—produced over 80% of emissions in the “other sources” category (119,024 MTCO2e).
