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 the prohibition on such installations does not apply to the replacement of components in existing space- or water-heating systems that utilize natural gas, oil, or other fossil fuels. This change aims to provide clarity regarding the maintenance and replacement of existing heating systems without imposing additional restrictions.

The bill includes several amendments to Section 109e of the original act, such as changing the terminology from "appliances" to "systems" and designating existing text as paragraph (1). Additionally, a new paragraph (2) is added to explicitly state that the replacement of components in existing heating systems is exempt from the restrictions. The act is set to take effect on January 1, 2025, and will remain in effect for a maximum of 90 days following approval by the Mayor or a Council override of a potential veto.
