BERDO Regulations Development
The Building Emissions Reduction and Disclosure Ordinance (BERDO) requires large buildings in Boston to:
- report their annual energy and water use to the City, and
- reduce their greenhouse gas emissions over time.
BERDO 2.0 is an important tool for helping Boston meet its climate goals. The first step for implementing BERDO is to develop and adopt regulations. The Air Pollution Control Commission reviews and adopts all BERDO regulations.
