The Evolving Role of International Carbon Credits in Europe’s Climate Ambition

In this latest article, Yiota Michou explores how high-integrity international carbon markets can complement domestic decarbonisation, mobilise private capital at scale, and support broader global climate action while maintaining strong environmental integrity and investor confidence.

As the EU shapes its 2040 climate framework, one question is becoming increasingly important: what role should international carbon credits play in delivering Europe’s climate ambitions?

The debate is often polarised. Critics see international credits as a distraction from domestic decarbonisation. Supporters see them as an essential tool for accelerating global mitigation and mobilising capital at scale. In reality, both climate ambition and market pragmatism matter — and Europe has an opportunity to strike the right balance.

The European Commission has proposed introducing a limited degree of flexibility within the EU’s pathway towards its 2040 climate target, including the potential use of international carbon credits equivalent to up to 5% of 1990 emissions levels. The proposal forms part of a broader discussion around how Europe can achieve increasingly ambitious climate objectives while maintaining competitiveness, cost-efficiency and a credible transition pathway.

This appears to represent a sensible and measured approach. Used correctly, international credits can complement domestic emissions reductions, not replace them. The objective should be to provide targeted flexibility where it adds value, while ensuring that strong incentives for emissions reductions within Europe remain firmly in place.

Why this discussion matters now

At Climate Asset Management, we recently contributed to the EU consultation process on this topic. Our position is straightforward: high-integrity international carbon markets can help Europe achieve its climate objectives more efficiently and support broader global climate action — provided the framework is designed appropriately.

The consultation itself signals an important evolution in Europe’s approach. The discussion around international credits has moved from a theoretical policy debate to a practical question within Europe’s climate architecture. As part of establishing the EU’s 2040 climate target, the European Commission launched a consultation on a potential legal framework for the use of international carbon credits, seeking views on key design questions including integrity requirements, governance approaches, removals methodologies and implementation mechanisms.

The significance of this goes beyond the proposed 5% flexibility itself. It reflects a broader recognition that the discussion is no longer simply about whether international credits should have a role, but how they can be incorporated in a way that supports climate ambition, investor confidence and effective market functioning.

Building confidence in the framework

Ultimately, the success of any international credit framework will depend on confidence in the quality and integrity of the underlying credits.

The future success of international carbon markets will depend entirely on confidence in the underlying credits. Investors, policymakers and corporates need assurance that emissions reductions and removals are real, measurable, additional and durable. That means robust methodologies, credible monitoring and verification, transparent accounting, and strong safeguards around permanence and leakage.

The role of international credits should ultimately be viewed through the lens of complementarity rather than substitution. Europe’s climate ambitions will continue to rely on significant domestic emissions reductions, with international credits functioning as a targeted flexibility mechanism rather than a replacement for domestic action. Striking this balance will be important in preserving strong incentives for emissions reductions within Europe while also enabling broader global climate impact.

Creating coherence across frameworks

As the EU develops its framework, maintaining consistency across evolving standards and mechanisms will also be important for providing clarity to investors and market participants. The development of the EU Carbon Removal Certification Framework (CRCF) is an important step in this direction, particularly for removals-focused activities.

For removals, there may be important opportunities for alignment between any future approach to international credits and the principles already being established through the CRCF. Areas such as monitoring, reporting and verification (MRV), additionality requirements, permanence approaches and transparency standards could benefit from greater consistency. While international credits and the CRCF are intended to serve different purposes, creating coherence across these frameworks could strengthen confidence and reduce unnecessary complexity for project developers and investors.

Over time, ensuring that emerging approaches to carbon markets and removals evolve in a coherent manner can help strengthen confidence, support market development and provide greater certainty for long-term capital allocation.

Why nature-based solutions matter

Importantly, the conversation should not focus solely on industrial decarbonisation. Nature-based solutions must play an important role within any credible international credit framework.

Forestry, regenerative agriculture and ecosystem restoration projects can deliver meaningful climate outcomes while also supporting biodiversity, water resilience, soil health and local livelihoods. These are precisely the types of projects capable of attracting long-term institutional capital when supported by robust governance and credible risk-management mechanisms.

Too often, debates around nature-based credits become fixated on the idea of “perfect permanence”. In practice, all climate solutions involve risk. The question is whether risks are transparently managed and appropriately mitigated. Conservative baselines, buffer mechanisms, long-term stewardship and rigorous monitoring can provide a credible foundation for high-integrity nature-based credits.

It is also important not to overlook the broader value that nature-based solutions can provide. Beyond their role in carbon mitigation and removals, these projects often deliver meaningful environmental and social co-benefits that support wider climate and nature objectives.

The EU also faces an important strategic choice around partner countries. Overly restrictive eligibility criteria could significantly limit the scale and effectiveness of international markets. Climate finance is often needed most in emerging markets, where mitigation opportunities can be substantial and where natural capital investments can generate meaningful benefits for both communities and ecosystems.

Looking ahead

From an investor perspective, regulatory clarity matters just as much as ambition. Long-term policy certainty, credible standards and efficient market processes will all be necessary to crowd institutional capital into climate and nature solutions at scale.

Ultimately, this debate is bigger than carbon accounting.

Done properly, the inclusion of international carbon credits within the EU’s climate targets can help channel investment into natural capital, resilient landscapes and climate solutions globally, while continuing to reinforce strong domestic decarbonisation efforts within Europe.

As the EU continues to refine its approach, the focus should be on creating a framework that combines environmental integrity with practical implementation. A clear and credible framework can provide the foundation for long-term investment and help unlock the role that private capital can play in accelerating climate and nature outcomes globally.
