OSE: 2026 Building Decarbonization Grants

2026 Building Decarbonization Grant Program Now Accepting Applications!

The Building Decarbonization Grant program is open to applications through August 10 and will award up to $4 million for projects at BEPS-covered buildings. These grants will help fund engineering design and capital retrofit projects to reduce greenhouse gas (GHG) emissions from recipient buildings ahead of BEPS compliance deadlines. As in 2025, OSE will prioritize buildings like nonprofits, affordable housing, senior housing, and other facilities serving frontline communities, as well as buildings whose current energy data show them exceeding upcoming BEPS greenhouse gas intensity (GHGI) targets. However, all buildings covered by BEPS are eligible and encouraged to apply. All grant information is posted on the Building Emissions Navigator webpage.
