Summary
D.C. law commits the Mayor to cut District-wide greenhouse gas emissions 45% below 2006 levels by 2025, 60% by 2030, 70% by 2035, 85% by 2040, and to carbon neutrality by 2045. District government operations must hit carbon neutrality even sooner, by 2040.
(a) The Mayor shall adopt policies to reduce emissions of greenhouse gases from both public and private sources to: (1) Not less than 45% below 2006 greenhouse gas emission levels by 2025; (2) Not less than 60% below 2006 greenhouse gas emission levels by 2030; (3) Not less than 70% below 2006 greenhouse gas emission levels by 2035; (4) Not less than 85% below 2006 greenhouse gas emission levels by 2040; and (5) A level consistent with carbon neutrality by 2045, and in each year thereafter. (b)(1) The District shall reduce emissions attributable to District government operations to a level consistent with carbon neutrality by 2040.
Full Breakdown
C. 09d requires the Mayor to adopt policies driving District-wide greenhouse gas emissions down on a fixed schedule: 45% below 2006 levels by 2025, 60% by 2030, 70% by 2035, 85% by 2040, and carbon neutrality by 2045 and every year after. A separate, faster track applies to the government's own operations: the District must reach carbon neutrality for its own buildings, fleet and facilities by 2040, prioritizing new renewable energy generation over offsets. C. C. Water, the Deputy Mayor for Planning and Economic Development, the Department of Energy and Environment, and the Office of Resilience and Recovery, to produce a funded, timelined 2040 action plan within 18 months of the September 21, 2022 enactment date.
The law folds equity into the mandate: in choosing how to hit these targets, the District must advance racial equity, redress past environmental and public health inequities, and favor measures with the least harmful effect on local ecosystems. Starting July 1, 2025, and every July 1 after, DOEE must report to the Council on progress, including an updated District-wide greenhouse gas inventory in tons of CO2 equivalent, a breakdown of actions taken, an equity and ecosystem analysis of those actions, and, if targets are missed, the specific impediments and fixes proposed.
Every five years the report must also project emissions out through 2045 (District-wide) and 2040 (government operations) under current policy. 09e, bars the District government from installing new fossil-fuel space or water heating in its own buildings starting January 1, 2025, and requires it to buy or lease only zero-emissions vehicles starting January 1, 2026, subject to narrow infeasibility and market-availability exceptions.
Violations & Fines
This section sets planning, reporting and procurement mandates for District government rather than a fine schedule directed at residents or businesses. Failure by an agency to hit an interim target triggers a required public explanation in DOEE's annual Council report rather than a monetary penalty; the enforceable teeth are the July 1 reporting deadline and the 18-month deadline for the 2040 government-operations action plan, both owed to the Council.
