European Commission, Brazil, and China launch a new platform to enhance transparency and effectiveness of carbon trading systems amid rapid global expansion of carbon pricing.
The European Commission, Brazil and China have formally launched the Open Coalition on Compliance Carbon Markets, a new international platform intended to tighten cooperation on carbon pricing and strengthen the credibility of domestic emissions trading systems and carbon taxes.
According to the European Commission, the initiative builds on a declaration endorsed at COP30 in Belém in November 2025 and is designed to improve the effectiveness, transparency and integrity of carbon markets as governments search for lower-cost ways to cut emissions. The coalition will focus on monitoring, reporting and verification, carbon accounting methods and the possible use of high-integrity offsets where they can support environmental integrity.
The launch comes at a time when carbon pricing is spreading rapidly. The Commission says there are now roughly 80 carbon pricing schemes in place across 50 countries, underlining the value of common standards and policy coordination. For industrial companies, that matters because compliance markets increasingly shape investment decisions in power, steel, cement, refining, chemicals and other carbon-intensive sectors.
The coalition’s timing also reflects the differing stages of market development among its founders. The EU has operated its Emissions Trading System since 2005 and is still refining the framework as policymakers weigh competitiveness pressures and energy-security concerns. China, meanwhile, launched the world’s largest national ETS in 2021 as part of its push to peak emissions before 2030 and reach carbon neutrality by 2060. Brazil passed legislation in 2024 to create its own emissions trading system.
The Commission said the coalition is open to countries with nationwide compliance carbon markets, including emissions trading systems and carbon taxes, while subnational authorities with carbon pricing schemes may join as observers. Brazil will chair the group for the first two years, with the European Commission and China serving as co-chairs. New Zealand and Germany are the first members to sign on, and more participants are expected.
Officials plan to set up a secretariat and adopt a work plan at the Carbon Market Conference in Wuhan on 15 September 2026. For decarbonisation professionals, the coalition signals a broader effort to make carbon markets more interoperable and more reliable at a time when policy convergence could become increasingly important for cross-border industry.

As confirmed on the host website of COP30 and in a joint statement from the European Commission, the initiative seeks to establish a cross-border cooperation framework that aligns national carbon pricing mechanisms, emissions trading systems (ETS), and related policies, creating a global compliance carbon market network that is interoperable, transparent, and credible. Operating on a fully voluntary basis, the coalition is open exclusively to interested countries and will remain receptive to new members following its initial formation. Christina Reis, Brazil’s Deputy Minister of Sustainable Economic Development at the Ministry of Finance, outlined the coalition’s core aim as accelerating national decarbonisation and advancing the Paris Agreement.
