EU climate target 2040 allows external credits as PIK paper proposes fund-based approach to safeguard integrity and lower costs
EU climate target 2040 now permits up to five percentage points of emissions reductions to come from projects outside the bloc, a PIK paper argues funds and rigorous rules can prevent fraud and cut costs.
The European Union has adopted a new mid-century step that would cut greenhouse gas emissions by 90 percent from 1990 levels by 2040, and for the first time allows up to five percentage points of that reduction to come from outside the bloc. This flexible element in the EU climate target 2040 has prompted sharp debate between campaigners who warn of loopholes and economists who say international credits, properly governed, can preserve ambition and reduce costs. A recent policy paper by researchers at the Potsdam Institute for Climate Impact Research (PIK) outlines a fund-based, rule-driven strategy that the authors say would deliver credible emissions savings while delivering financial benefits to partner countries.
EU decision and the scope of external credits
The new EU climate target 2040 replaces a previous Commission proposal that would have allowed three percentage points of external credits, expanding the allowance to five percentage points after member-state negotiations. The measure supplements the bloc’s existing 2030 and 2050 commitments, keeping the long-term goal of a climate-neutral continent intact while adding room for internationally sourced mitigation. Proponents argue the flexibility helps the EU maintain political feasibility even if global actions diverge, but critics caution it risks undermining domestic decarbonization efforts.
PIK economists’ defense of international flexibility
Researchers at PIK — including Ottmar Edenhofer, Christopher Leisinger, Lennart Stern and Matthias Kalkuhl — argue that international mitigation can act as a stabilizer for EU policy rather than a substitute for domestic ambition. Their analysis contends that carefully designed international payments and funds can secure genuine emissions reductions overseas and permit the EU to meet its 2040 target more efficiently. The authors calculate that directing pooled funding toward high-impact interventions could be far cheaper per ton of avoided CO2 than relying solely on reductions inside the EU.
Fraud risks and verification challenges
Skeptics point to a history of weakly verified credits and high-profile scandals, such as instances of falsified certificates in China, to underline the risks of outsourcing emissions reductions. The PIK paper acknowledges that bilateral project approaches are vulnerable to manipulation, additionality failures and “government crowding out,” where domestic incentives to act are weakened because external financing may take over. Robust monitoring, transparent criteria and independent verification are therefore central to preventing fraudulent or double-counted savings, the researchers insist.
Fund-based model and rainforest fund example
To address those weaknesses, the PIK authors propose channeling EU support through purpose-built funds rather than negotiating narrow bilateral deals for individual projects. Under this model, pooled resources would be distributed based on measurable outcomes — for example, reduced deforestation detected via satellite imagery — instead of promises or planned activities. The Tropical Forests and Food Fund (TFFF), launched at a recent climate summit, serves as an existing example of a multilateral mechanism that the EU could scale or join to help meet its five-point international allowance.
Cost advantages and market implications
The economists estimate that a diversified fund strategy focused on reducing coal, oil and gas use in developing countries could achieve international reductions for as little as 21 euros per ton of CO2 avoided. That figure compares favorably with prices inside the EU Emissions Trading System, which are currently substantially higher and are expected to rise. The PIK analysis suggests that by lowering near-term demand for emissions inside the bloc, such funds could also ease pressure on EU carbon prices between 2036 and 2050, reducing costs for industry and households while preserving the long-term transition pathway.
Potential co-benefits and partner-country gains
Beyond climate metrics, the proposed fund approach could deliver economic advantages to partner countries, the paper argues, by channeling more finance than the administrative cost of projects alone would imply. PIK researchers estimate recipient nations could obtain roughly double the direct project costs in broader financial inflows under a transparent, rule-based fund system. That outcome, they say, would strengthen political incentives for host governments to participate and to sustain emissions reductions over time.
The EU’s new flexibility in the 2040 target raises a policy choice between strict territorial action and a blended approach that uses international cooperation to augment domestic measures. The PIK team makes a case that, with tight rules, independent verification and pooled finance mechanisms such as rainforest and fossil-fuel-substitution funds, the EU climate target 2040 can be met without diluting environmental integrity and at a lower economic cost. Rapid action will be essential, the researchers warn, because other global actors could bid for the same high-impact opportunities, narrowing the pool of affordable mitigation options available to the EU.
The coming months will test whether Brussels adopts the fund-based safeguards PIK recommends, and whether member states agree on the governance, transparency and verification standards necessary to make external credits credible. If designed and implemented well, international funds could complement the EU’s domestic transition while protecting both climate outcomes and taxpayers.
