Sixteen Nations Sign Landmark Agreement to Quadruple Global Carbon Markets

2026-11-13 global

Antalya, Friday, 13 November 2026.
At COP31, sixteen nations unveiled a targeted policy playbook to mobilize private climate finance, aiming to quadruple the international carbon credit market to $21 billion by 2035.

A New Framework for Climate Finance

Sixteen nations, convening at the COP31 climate summit in Antalya, Türkiye, have signed the Antalya Statement, a landmark agreement to expand international carbon credit markets and mobilize private sector capital for climate action. The declaration, unveiled on November 13, 2026, introduces a synchronized policy playbook designed to quadruple the global carbon credit market value to US$21 billion by 2035 [1]. This initiative seeks to establish clearer cross-border regulatory standards, enhance market liquidity, and create a more predictable framework for voluntary and compliance-based offset trading [1].

The Policy Playbook: Eight Levers for Transformation

Central to the Antalya Statement is a Policy Playbook outlining eight targeted policy levers intended to drive market expansion. These measures include harmonizing carbon pricing mechanisms, streamlining cross-border transactions, and incentivizing private investment in high-integrity carbon projects [1]. The playbook’s implementation aims to address fragmentation in existing carbon markets, which have historically struggled with inconsistent standards and regulatory barriers [1]. By aligning policies across jurisdictions, the agreement seeks to unlock capital flows that can accelerate decarbonization efforts globally [1].

Expanding Membership and Global Commitments

The Antalya Statement was signed by 14 countries at its launch, including Canada, France, Indonesia, Ireland, Italy, Kenya, Luxembourg, New Zealand, the Philippines, Singapore, Switzerland, Türkiye, the UK, and Zambia [1]. Egypt and Ireland later announced their intention to join the coalition, bringing the total to 16 signatories [1]. H.E. Murat Kurum, Türkiye’s Minister of Environment, Urbanisation and Climate Change, emphasized the role of carbon credit markets in supporting the climate finance architecture, stating: ‘Globally aligned, high-integrity carbon credit markets support the achievement of climate goals and the implementation of COP31 priorities, including the Climate Implementation Bridge goal’ [1].

Reactions from Global Leaders and Institutions

The announcement has garnered support from global institutions and business leaders. Peter Bakker, President and CEO of the World Business Council for Sustainable Development (WBCSD), welcomed the playbook as a practical guide for governments to establish clear rules for corporate climate strategies. Bakker noted: ‘Companies want to use high-integrity carbon credits as part of credible climate strategies, but they need clear rules to invest with confidence’ [1]. The WBCSD’s endorsement underscores the private sector’s demand for regulatory certainty in carbon markets. Additionally, the UK announced plans to issue market guidance for organizations in spring 2027 and introduce a $1 million CORSIA access program to facilitate carbon credit trading [1].

Broader Context: Climate Finance and Policy Shifts

The Antalya Statement arrives amid broader discussions on climate finance at COP31, where world leaders are grappling with the urgent need to scale up investment in decarbonization. UN Secretary-General António Guterres, in his opening remarks at the summit, called for a ‘climate justice compact’ to tax fossil fuel companies and redirect funds to vulnerable nations [3]. Guterres warned that current national climate plans risk overshooting the 1.5°C warming limit, while fossil fuel giants earned $95 billion in a single quarter compared to the $600 million allocated to the international loss and damage fund [3]. His remarks highlighted the stark disparity between the financial capacity of high-emitting industries and the needs of countries most affected by climate change. [alert! ‘The $600 million figure refers to cumulative funding for the loss and damage fund as of November 2026, per [3].’]

Next Steps: Roundtable and Implementation Roadmap

Ministers and climate envoys are scheduled to convene on Monday, November 16, 2026, for a roundtable hosted by the Coalition to Grow Carbon Markets and the Türkiye COP31 Presidency [1]. This meeting will focus on operationalizing the Policy Playbook’s recommendations and advancing the Climate Implementation Bridge, a framework designed to mobilize climate finance at scale [1]. The coalition’s efforts align with the COP31 Action Agenda, which emphasizes electrification, green industrialization, and resilience as key priorities for transitioning away from fossil fuels [5].

Market Implications and Future Outlook

The expansion of carbon credit markets holds significant implications for multinational corporations and financial institutions, which now have a clearer regulatory path for offset trading. The Policy Playbook’s target of US$21 billion by 2035 represents a 300 300% increase from the estimated 2026 market value of US$5.25 billion [GPT][alert! ‘The 2026 baseline market value is inferred from the playbook’s quadrupling target of $21 billion by 2035.’] The agreement’s emphasis on high-integrity credits is expected to attract institutional investors seeking credible climate solutions. However, challenges remain in ensuring consistent enforcement of standards across jurisdictions and preventing double-counting of emissions reductions [1].
