After an intense overnight negotiation session, the European Union’s 27 member states have struck a compromise deal to enshrine new climate goals, setting the stage for the bloc’s next phase of decarbonization. The agreement establishes a 2040 target to cut greenhouse gas (GHG) emissions by 90% compared with 1990 levels but introduces greater flexibility through a bigger role for international carbon credits and a delay to the EU’s expanded carbon pricing system (ETS2).

Balancing Ambition with Economic Reality

The 2040 target, first proposed by the European Commission in July, is designed as a key step toward the EU’s legally binding 2050 climate neutrality goal. While the bloc has already achieved a 37% reduction in emissions since 1990 and is on course to meet its 55% by 2030 target, several governments notably Poland, Hungary, and the Czech Republic resisted stricter mandates, warning of potential economic strain and energy security risks. To secure consensus, negotiators agreed to a broader use of international carbon credits, allowing countries to offset up to 5% of their total reduction requirement through emissions savings achieved outside the EU. This raises the initial allowance from 3%, with an option to add another 5% “under exceptional circumstances” if domestic reduction targets prove too burdensome. The compromise signals a strategic recalibration: maintaining high ambition on paper while giving industries and member states additional tools to meet targets cost-effectively.

Carbon Markets Take Center Stage

The deal reinforces the role of global carbon trading as a practical instrument in achieving Europe’s net zero trajectory. By aligning with Article 6 of the Paris Agreement, the EU opens the door for cross-border emissions trading and investment in international decarbonization projects, such as reforestation, renewable energy, and methane abatement in developing countries. However, environmental advocates caution that expanding carbon credit usage could dilute domestic climate action. Critics argue that over-reliance on offsets risks delaying structural reforms in high-emission sectors such as transport, heavy industry, and building heating, all central to Europe’s long-term transition.

ETS2 Launch Deferred to 2028

In another significant adjustment, the EU has postponed the rollout of its new Emissions Trading System (ETS2) by one year, from 2027 to 2028. ETS2 will extend carbon pricing to road transport fuels and building heating, sectors that directly impact households. Member states sought the delay to cushion consumers from potential price shocks and allow more time for national energy transition measures to mature. The EU’s original Emissions Trading System (ETS), launched in 2005, remains one of the world’s largest carbon markets, covering power generation and industrial emissions. The new ETS2 represents its most ambitious expansion yet, designed to drive decarbonization at the consumer level.

New 2035 Milestone and NDC Submission

The agreement also introduces a new 2035 interim goal, setting a GHG reduction range of 66.25% to 72.5% (based on 2019 levels). This milestone will form the backbone of the EU’s updated Nationally Determined Contribution (NDC) under the Paris Agreement, which every signatory nation must renew every five years with increasing ambition. Although the EU missed its September deadline to formally submit the revised NDC ahead of COP30 in Belém, Brazil, the compromise deal now clears the way for an official submission in time for the global summit.

Political and Industrial Implications

For Brussels, the deal is both a diplomatic and economic balancing act. It provides businesses with policy certainty while ensuring the EU can present a credible climate leadership narrative on the international stage.

“Today’s deal gives business the predictability they desperately need here in Europe,” said Wopke Hoekstra, Commissioner for Climate, Net Zero and Clean Growth. “It also gives us a strong hand in international negotiations because we’ll be going to COP30 with an ambitious EU NDC.”

While environmentalists view the compromises as a step back from full domestic action, policymakers argue the outcome reflects pragmatic realism ensuring that Europe’s climate ambition remains politically and economically sustainable through the next decade. As the EU heads toward COP30, the 2040 framework represents both a test of climate unity and a template for balancing environmental goals with industrial resilience in an increasingly polarized global energy landscape.
