MAYOR

The Honorable Phil Mendelson
Chairman
Council of the District of Columbia
1350 Pennsylvania Avenue, N.W., Suite 504
Washington, DC 20004
Dear Chairman Mendelson:
Enclosed for consideration by the Council is proposed emergency legislation entitled the “Climate
Commitment Clarification Emergency Declaration Resolution of 2024” and the “Climate
Commitment Clarification Emergency Amendment Act of 2024” This legislation will clarify that
the Department of General Services (DGS) is allowed to repair and replace units and component
parts of fossil fuel-based heating and cooling systems.
The current law mandates that the District may not install fossil fuel-based space or water heating
appliances. The law is intended to advance electrification, decreasing fossil fuel consumption
across the District. It is unclear, however, how DGS will continue to maintain existing fossil fuel-
based systems without replacing each system through a modernization or planned whole system
HVAC replacement project. A modernization or whole system HVAC replacement project for any
site requires multiple years to formulate and request a budget; develop, solicit, and evaluate
proposals; perform design review; engage stakeholders; swing occupants to an empty building;
and build or install the project -- all of which must be strategically planned.
To date, the District has over 300 fossil fuel-based space heating appliances alone. There is
insufficient time, budget, and materials to switch every building to an all-electric system. There
would also be significant embodied carbon emissions associated with doing so. Hundreds of fossil
fuel-based systems possess many additional years of useful life to provide heating to the District
through the winter season and beyond.
To wisely steward the District government’s limited resources and achieve the useful life of
existing systems, DGS will replace fossil fuel-based systems with all electric once these systems
are beyond repair or when deemed fully inoperable and appropriate for HVAC replacement.
Approval of the enclosed emergency declaration and approval of the emergency legislation will
facilitate the ongoing maintenance of existing fossil fuel-based systems throughout the District.
I look forward to your prompt and favorable consideration of this resolution. In order to facilitate
a response to any questions you may have, please have your staff contact Director Delano Hunter.
Sincerely,
Muriel Bowser

MEMORANDUM
TO: The Honorable Phil Mendelson
Chairman, Council of the District of Columbia
FROM: Glen Lee
Chief Financial Officer
DATE: November 26, 2024
SUBJECT: Fiscal Impact Statement – Climate Commitment Clarification
Emergency Amendment Act of 2024
REFERENCE: Draft bill provided to the Office of Revenue Analysis on November 22,
2024
Conclusion
Funds are sufficient in the fiscal year 2025 through fiscal year 2028 budget and financial plan to
implement the bill.
Background
Beginning January 1, 2025, current law1 prohibits the District from installing, in District-owned
buildings, space- or water-heating appliances that rely on the combustion of natural gas, oil, or other
fossil fuels at the site of the appliance, except in cases where compliance would be technically
infeasible.
The bill modifies the law to apply to the installation of building systems, not the individual
components or units within existing systems.
Financial Plan Impact
Funds are sufficient in the fiscal year 2025 through fiscal year 2028 budget and financial plan to
implement the bill. Narrowing the application of the requirement from all components of a building
system to the replacement of the whole system does not have an added cost.
