Boston, MA
Boston's BERDO requires annual reporting and, separately, holds buildings to declining emissions limits. The city has moved its reporting deadline before, so the date below is checked against the city's own notices.
BERDO annual report
In effect
Report whole-building energy and water use to the City of Boston. The Review Board extended the 2026 deadline from May 15 to August 15, so confirm the current year's date before relying on it.
