BERDO 2.0: What is it and who does it Impact?
In the fight to curb greenhouse gas emissions in Boston, buildings remain the largest obstacle. Buildings account for nearly 70% of greenhouse gas emissions in Boston. The 2021 amendment to BERDO gives the City authority to set carbon emissions standards for large existing buildings. The emissions standards will decrease over time, with all buildings achieving net zero emissions by 2050.
The ordinance requires covered buildings to report their annual energy and water performance to the City. Covered buildings are defined below. A detailed 2023 BERDO Covered Buildings List can be found within the "BERDO Covered Buildings List."
- Nonresidential buildings that are 20,000 square feet or larger (excluding parking).
- Residential buildings that have 15 or more units.
- Any parcel with multiple buildings that add up to at least 20,000 square feet (excluding parking) or have 15 or more residential units. All buildings on the parcel must report their annual energy and water use individually.
- Buildings owned by the City of Boston and Boston Housing Authority.
