Türkiye has been accepted as a member of the Open Coalition on Compatibility of Carbon Markets, according to an announcement.
According to a statement by the Presidency for Climate Change, Türkiye’s membership was conveyed in an official letter from Brazil, the coalition’s chair, dated Aug. 11, 2026.

The statement said the letter highlighted the contribution Türkiye’s institutional and technical work on carbon markets could make to the coalition. It also emphasized the importance of Türkiye’s upcoming COP31 presidency for maintaining cooperation in the transition from COP30 to COP31.

Coalition Founded at COP30

The initiative, which aims to facilitate the integration of carbon markets in different countries around the world, was launched at the COP30 Leaders’ Summit held in Belém in November 2025.

The initiative, developed under Brazil’s leadership, was established with the participation of Brazil, the European Union, Germany, the United Kingdom, China, Armenia, France, Mexico, Chile, Canada and Zambia, which together account for 40 percent of global emissions.

Seven additional members subsequently joined, bringing the coalition’s membership to 17, and a declaration establishing the coalition was issued.

The coalition’s institutional structure was established at its first High-Level Meeting, held in Florence in May 2026. Brazil was designated as the coalition’s chair for its first two-year term, with China and the European Commission serving as co-chairs.

Work Plan to Be Set at Sept. 15 Conference

The coalition’s work plan is expected to be developed at the Carbon Market Conference to be held in Wuhan, China, on Sept. 15, 2026.

The coalition’s technical work will focus on strengthening monitoring, reporting and verification (MRV) systems, improving carbon accounting methodologies, and exploring the potential use of high-integrity credits to safeguard environmental integrity.
Countries with functioning national carbon markets, including emissions trading systems and carbon taxes, are eligible to join the coalition.
