The City of Bellevue is taking steps to reduce greenhouse gas emissions. In 2007, the City Council signed on to the Mayors' Climate Protection Agreement, and the recommended 2020 Environmental Stewardship Plan recommends reducing greenhouse gas emissions 50% by 2030 and 80% by 2050. 

The city tracks greenhouse gas emissions for both government operations and the entire community on an annual basis. To learn more about Bellevue's greenhouse gas emissions, check out our Environmental Performance Dashboard.

The City of Bellevue is part of the King County-Cities Climate Collaboration (K4C), an innovative partnership between King County and 17 partners — Bellevue, Burien, Issaquah, Kenmore, Kent, Kirkland, Lake Forest Park, Mercer Island, Normandy Park, Port of Seattle, Redmond, Renton, Sammamish, Seattle, Shoreline, Snoqualmie, and Tukwila — to coordinate and enhance the effectiveness of local climate and sustainability action.

Bellevue joined the K4C in 2014 and signed the original K4C Joint Commitments in 2015.  The K4C Joint Commitments were refreshed in late 2019, and Bellevue signed the updated K4C Joint Commitments in September 2020.

Bellevue's Carbon Yeti wants to help you learn how to reduce your carbon footprint. Check out the Yeti House to explore ideas for reducing your carbon footprint and the "Smaller Footprint Pledge" book.

Here are some easy things you can do to reduce your carbon footprint:

  • Recycle half of your household waste. (Save 2,400 pounds of carbon dioxide per year.)
  • Compost all of your food waste. (Save 3,200 pounds of carbon dioxide per year.)
  • Reduce your garbage 10 percent by avoiding over packaged products. (Save 1,200 pounds of carbon dioxide per year.)
  • Drive less. Here are some alternatives to driving solo.
  • Turn your thermostat down in the winter -- from 70 degrees to 68 degrees -- and up in the summer -- from 70 degrees to 72 degrees. (Save 2,000 pounds of carbon dioxide per year.)
  • Install a water-efficient showerhead to use less hot water. (Save 350 pounds of carbon dioxide per year.)
  • Insulate your water heater. (Save 1,000 pounds of carbon dioxide per year.)
  • Run ceiling fans in your home instead of air-conditioning. (Save up to 2,700 pounds of carbon dioxide per year.)
  • Use a power strip for your computer, monitor, fax, copier, iPod and cell-phone chargers and any other electronic equipment; then switch it off when they are not in use. (Save 2,000 pounds of carbon dioxide per year.)
  • Drink tap water instead of bottled. (Save 52 pounds of carbon dioxide per year or 2 pounds per gallon jug.)
  • Check and inflate your tires monthly. (Save 250 pounds of carbon dioxide per year.)
  • Plant one tree. (Save 2,000 pounds of carbon dioxide over the lifetime of the tree.)
