International Conversations on Trade and Climate: From the World Trade Organization to the United Nations Framework Convention on Climate Change

The research paper examines the transition of trade-related climate measures from abstract policy debates to concrete implementation between 2025 and early 2026. It highlights the role of the European Union's Carbon Border Adjustment Mechanism (CBAM) and the EU Deforestation Regulation as primary drivers of international tension. The authors analyze discussions within the WTO's Committee on Trade and Environment (CTE) and the Trade and Environmental Sustainability Structured Discussions (TESSD), as well as new initiatives established at COP 30 in Brazil, including the 'Mutirão' technical dialogues and the Integrated Forum on Climate Change and Trade (IFCCT). The paper argues that MC14 serves as a critical moment for consolidating these debates around transparency, interoperability, and development support.

• Between 2025 and early 2026, climate-related trade measures shifted from theoretical debate to practical application, exemplified by the EU's Carbon Border Adjustment Mechanism (CBAM) entering its definitive phase in January 2026. Other nations are following suit or preparing similar frameworks: the UK's CBAM is set for January 1, 2027, while Australia, Canada, and Chinese Taipei are exploring similar instruments, and Brazil and Türkiye are addressing carbon leakage risks in their legislation.
• The European Council adopted a targeted revision of the EU Deforestation Regulation in December 2025, setting compliance deadlines of December 30, 2026, for large and medium operators, and June 30, 2027, for small and medium enterprises.
• WTO discussions in 2025 revealed three primary themes regarding Trade-related Climate Measures (TrCMs): equity and development concerns (particularly from the African and LDC Groups), fragmentation and compliance costs (highlighted by China and Japan), and the WTO's role as a forum for technical cooperation and transparency.
• The WTO's Committee on Trade and Environment (CTE) has focused on three pillars for 2026: transparency, interoperability, and the development dimension. Additionally, the Trade and Environmental Sustainability Structured Discussions (TESSD) produced a Compilation and Mapping of Trade-related Climate Policies to be presented at MC14.
• COP 30 in Belém, Brazil, introduced trade topics into the UNFCCC framework through two main initiatives: the 'Mutirão' decision, which establishes three technical dialogues for 2026-2028, and the Integrated Forum on Climate Change and Trade (IFCCT), a non-binding, non-negotiated, and non-attributable initiative also running until 2028.
