The Climate Commitment Clarification Temporary Amendment Act of 2025 seeks to amend the District Department of the Environment Establishment Act of 2005 by clarifying that the act does not apply to the replacement of components or units of existing space- or water-heating systems that utilize the combustion of natural gas, oil, or other fossil fuels. The bill includes several amendments to Section 109e, such as changing the terminology from "appliances" to "systems" and designating existing text as paragraph (1). Additionally, a new paragraph (2) is introduced, explicitly stating that the subsection does not apply to the replacement of components of these heating systems.

The act is set to take effect on January 1, 2025, following the necessary approval processes, including a 30-day congressional review period. It is designed to expire on September 3, 2025, unless further action is taken. The bill also adopts the fiscal impact statement from the Chief Financial Officer as required by legislative procedures.
