Open Coalition on Compliance Carbon Markets

• 1. Coalition Genesis And Formation

  ›

  The United Nations Climate Conference 2025 COP30 in Belém, Brazil became the birthplace of a new global alliance. President Luiz Inácio Lula da Silva stood alongside Silvia and Carl XVI Gustaf of Sweden to announce the Open Coalition on Compliance Carbon Markets. This group also goes by the name Climate Coalition. The plan aims to establish a global emissions cap starting at a level close to current emissions. It will then gradually reduce that cap until reaching net zero by 2050. For any activity that generates emissions, participants would be required to purchase allowances. As the cap declines, allowance prices would rise, creating an incentive for decarbonization. A border adjustment mechanism would also be implemented and jointly governed by all participants. Lower-income countries may pay reduced amounts or be exempt from some costs. Part of the revenue would be used to support their climate-related needs.

  By the 15th of November, eighteen countries had joined the coalition. The European Union and China joined Brazil as members. The list included the UK, Canada, Chile, Mexico, Armenia, Zambia, Rwanda, Andorra, Guinea, New Zealand, Monaco, Singapore, and Norway. Rafael Dubeux, deputy executive secretary of Brazil's Ministry of Finance, stated: All that is needed is a coalition strong enough to move forward. He added that if it includes Brazil, the EU, and China, it could encourage others to join. The coalition intends to begin with sharing best practices in monitoring, reporting and verification. They aim to establish common carbon accounting standards. The Niskanen center notes that these members are working on mandatory carbon pricing frameworks. These frameworks incentivize emission reduction domestically. They provide a competitive edge when facing border charges on exports.

  A group of academics around MIT proposed a specific financial structure for this alliance. Their report suggests a carbon price floor of US$50 per tonne of CO2 equivalent for all Climate Coalition members. This model includes a border carbon adjustment mechanism. The implementation of the plan will result in coalition members reducing emissions seven times faster than they do today. It generates approximately USD 200 billion per year for clean-energy and social programs. A moderate rise in prices occurs in certain industries, but there are minimal losses for producers. The proposal works similarly to the G7 proposal of a climate club. It remains distinct from the Brazilian proposal to launch a UNFCCC / World Trade Organization forum on climate and trade.

  Research published in Nature offers critical data on the potential impact of this initiative. The study indicates the coalition can close the emissions gap between current trajectories and Paris Agreement goals. Current paths direct the world to a 2.8 degrees warming by 2100 without intervention. The project aims to redirect the needed amount of money to climate action. Success depends heavily on an appropriate political climate. The academic findings suggest that global cooperation could significantly alter future temperature projections. Financial resources would flow toward necessary adaptation and mitigation strategies. These outcomes rely on sustained commitment from participating nations.

• 5. Geopolitical Implications For The United States

  ›

  The coalition has a strong impact on the United States of America. Seven member countries account for more than two-thirds of U.S. goods exports. Generally, American industry is considered as low carbon. However, some policies of Donald Trump are fastly destroying this advantage. For American exporters to not lose their carbon advantage, the United States needs to implement a mechanism for cutting emissions. On the 7th of January, the Council of the European Union is expected to begin discussion about the first step of the non-binding instrument procedure. This timeline creates immediate pressure for domestic policy adjustments. Trade relationships will shift based on how quickly Washington responds to these new international standards.
