The Climate Commitment Clarification Emergency Amendment Act of 2025 amends the District Department of the Environment Establishment Act of 2005 to clarify the restrictions on installing fossil fuel-burning systems. Specifically, the bill states that these restrictions do not apply to the replacement of components of existing space- or water-heating systems that utilize natural gas, oil, or other fossil fuels. The amendments include changes to the section heading and the language within the existing text to replace "appliances" with "systems" and to introduce a new provision that explicitly allows for the replacement of components in existing systems.

The act is set to take effect on January 1, 2025, following approval by the Mayor or a potential override of a veto by the Council. It is designed as an emergency measure and will remain in effect for no longer than 90 days, in accordance with the emergency act provisions of the District of Columbia Home Rule Act. The bill also adopts the fiscal impact statement from the Budget Director as required by legislative procedures.
