**SUPPLEMENTARY INFORMATION:**
**I. Background**
Article 24.26 of the USMCA establishes an Environment Committee composed of senior government representatives to oversee the implementation of Chapter 24 (Environment), and provide a forum to discuss and review chapter implementation. The USMCA requires the Committee to meet within one year of the date of entry into force of the USMCA and every two years thereafter unless the Committee agrees otherwise. The Committee last held a biannual meeting on September 26, 2023. The Committee also met in special sessions twice in 2025 (February and June) for the purpose of conducting the requisite five-year review of Chapter 24 (Article 24.26.7). All decisions and reports of the Committee will be made publicly available, unless the Committee decides otherwise. The Committee will provide for public input on matters relevant to the Committee's work, as appropriate, and hold a public session at each meeting.
**II. Committee Meeting**
On December 11, 2025, the Committee will meet in a government-to-government session to (1) review the implementation and operation of Chapter 24, in accordance with Article 24.26(7)(a) of the USMCA and (2) receive a presentation from the Commission on Environmental Cooperation (CEC) Secretariat on cooperation and public Submissions for Enforcement Matters (SEMs). This session will not be open to the public.
**III. Public Session on USMCA Chapter 24 Implementation**
Following the government-to-government session, the Committee invites all interested persons to attend a virtual public session on USMCA Chapter 24 implementation. At the session, the Committee will welcome questions and input concerning the Parties' implementation of the Chapter 24 obligations. The Committee will cover both questions raised in comments submitted to USTR, and those submitted through a live chat function, during the public session, overseen by a moderator. Email Judith Webster, Director for Environment and Natural Resources, at *[email protected]* for a link to join the live session. Registration is required by December 5, 2025.
**IV. Comments**
USTR invites all interested persons to submit their interest in participating in the public session, as well as comments on the implementation and operation of Chapter 24. As noted, during the public session, there will also be an allotted time for the public to ask questions through a chat function that a moderator will oversee. Accordingly, participation in the public session is not limited to those questions submitted through comments in advance of the session. When preparing comments, we encourage submitters to refer to Chapter 24 of the USMCA: *https://ustr.gov/sites/default/files/IssueAreas/Environment/USMCA_Environment_Chapter_24.pdf* .
