Building Decarbonization Grants

Seattle’s Office of Sustainability & Environment (OSE) is now accepting applications for its 2026 Building Decarbonization Grants through August 10. The City of Seattle will offer up to $4 million in grants to help owners of buildings larger than 20,000 square feet reduce climate pollution, or “decarbonize,” their buildings. 

The grants will help fund engineering design and/or capital upgrades to buildings ahead of future emissions reduction targets set by Seattle’s Building Emissions Performance Standard (BEPS) law, under which most large buildings will need to achieve net-zero emissions by 2050. Learn more, get connected with resources, and apply on the website.
