Boston City Council Committee Advances Stricter Energy Emissions Caps for Commercial High-Rises

BOSTON, MA — The Boston City Council Committee on Environmental Justice, Resiliency, and Parks advanced key amendments to the Building Emissions Reduction and Disclosure Ordinance (BERDO 2.0), tightening operational greenhouse gas emissions caps for commercial buildings over 35,000 square feet.

Accelerating Decarbonization in Commercial Real Estate

The updated ordinance establishes hard emissions limits for fossil-fuel heating systems starting in 2027 and increases non-compliance alternative compliance payments to $234 per metric ton of CO2 equivalent. Fund proceeds will be channeled directly into the Boston Equitably Decarbonizing Buildings (BEDB) Grant Program to retrofit triple-deckers and public housing developments in Dorchester, Mattapan, and Roxbury.

Committee leadership affirmed that large commercial towers generate over 70% of Boston's carbon footprint, requiring commercial real estate leaders to transition to heat pumps and geothermal systems.

Real Estate Federation and Community Reaction

Greater Boston Real Estate Board representatives requested flexible phase-in schedules for historic commercial properties facing supply chain delays for commercial electrical switchgear.

Climate justice coalitions praised the reinvestment of emissions compliance penalties into low-income neighborhood retrofits.

Final Council Approval Schedule

The full Boston City Council will take up the amended BERDO regulations during the September 9, 2026, legislative session.
