Overview
The Open Coalition on Compliance Carbon Markets was launched to strengthen the effectiveness, transparency and integrity of domestic carbon pricing and support implementation of the Paris Agreement; it builds on a declaration endorsed at COP30 in Belém, Brazil.
Membership and governance
Membership is open to countries with nationwide compliance carbon markets (emissions trading systems or carbon taxes); subnational schemes may participate as observers. Brazil will chair for the first two years, with China and the European Commission as co-chairs, and New Zealand and Germany are inaugural members.
Work programme and priorities
The Coalition will focus on robust monitoring, reporting and verification (MRV), comparable carbon accounting methodologies to facilitate corporate compliance across systems, and promoting high‑integrity carbon credits and offsets, building on Article 6.4 workstreams.
Next steps
The Coalition has adopted Terms of Reference, will establish a Secretariat and develop a workplan to be adopted at the Carbon Market Conference on 15 September 2026 in Wuhan; roughly 80 carbon pricing schemes operate across about 50 countries, motivating coordinated standards and cooperation.
