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

This research paper by Ieva Baršauskaitė and Antoine Bonnet analyzes the transition of trade-related climate measures from abstract policy debates to practical implementation between 2025 and early 2026. It examines the evolving roles of the World Trade Organization (WTO) and the United Nations Framework Convention on Climate Change (UNFCCC) in managing issues of transparency, interoperability, and development equity, positioning the 14th Ministerial Conference (MC14) as a critical juncture for consolidating these international efforts.

• Between 2025 and early 2026, climate-related trade measures shifted from theoretical debate to concrete application. The European Union's Carbon Border Adjustment Mechanism (CBAM) entered its definitive phase in January 2026, with a proposed expansion that could add 180 steel- and aluminum-intensive products, such as appliances and machinery. Additionally, the United Kingdom's CBAM is set to enter into force on January 1, 2027, while Australia, Canada, and Chinese Taipei are exploring similar instruments.
• The European Council formally adopted a targeted revision of the EU Deforestation Regulation in December 2025. This regulation sets compliance deadlines of December 30, 2026, for large and medium operators, and June 30, 2027, for small and medium enterprises.
• WTO discussions in 2025, involving 67 members and eight groups through 251 communications, centered on three recurring themes: equity and development concerns (specifically regarding market access and 'Common But Differentiated Responsibilities and Respective Capabilities'), fragmentation and compliance costs (with China focusing on interoperability and Japan on embedded emissions measurement methodologies), and the WTO's role as a technical and transparency forum.
• The WTO's Committee on Trade and Environment (CTE), under Chair Erwin Bollinger, has focused on three pillars for 2026: transparency, interoperability, and the development dimension. Separately, 79 members in the Trade and Environmental Sustainability Structured Discussions (TESSD) produced a Compilation and Mapping of Trade-related Climate Policies to be presented at MC14.
• At COP 30 in Belém, Brazil, the trade topic was introduced into UNFCCC conversations through two initiatives: a 'Mutirão' decision establishing three technical dialogues for 2026, 2027, and 2028, and the Brazilian COP Presidency's Integrated Forum on Climate Change and Trade (IFCCT), which will be non-binding, non-negotiated, and non-attributable for an initial 3-year phase until the end of 2028.
