The Climate Commitment Clarification Temporary Amendment Act of 2025 amends the District Department of the Environment Establishment Act of 2005 to specify that the act does not apply to the replacement of components or units of existing space- or water-heating systems that utilize natural gas, oil, or other fossil fuels. The bill includes several amendments to Section 109e, including changes to the section heading and the designation of existing text as paragraph (1). Notably, it replaces the term "appliances" with "systems" and introduces a new paragraph (2) that explicitly states the exemption for the replacement of components in these heating systems.

The act is set to take effect on January 1, 2025, following the necessary approval processes, and will expire on September 3, 2025. The fiscal impact statement associated with the bill has been adopted from the Chief Financial Officer, ensuring that the financial implications of the amendment are accounted for.
