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 fossil fuels such as natural gas or oil. 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 references to "appliances" with "systems" and introduces a new paragraph (2) that explicitly states the exemption for fossil fuel-based 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. Additionally, the Council has adopted the fiscal impact statement from the Chief Financial Officer as required by legislative procedures. This temporary amendment aims to clarify the scope of the original act in relation to existing heating systems, thereby providing a clearer regulatory framework for such replacements.
