A growing coalition of European industrial groups and climate policy organisations is warning the European Commission that its current approach to carbon credit recognition under the Carbon Border Adjustment Mechanism (CBAM) could undermine the effectiveness of one of the EU’s most important climate and trade tools.
At the centre of the dispute is a technical but highly consequential question: should carbon credits count as part of the carbon price paid in third countries when calculating CBAM liabilities? The Commission’s draft implementation rules suggest that certain carbon costs incurred outside the EU could be deducted from the number of CBAM certificates importers must surrender. In principle, this is intended to avoid double charging and ensure that exporters are not penalised where a genuine carbon price already exists.
But industry groups argue that the definition of a “real” carbon price is now being stretched too far.
Core concern: carbon credits versus EU ETS discipline
The coalition behind the warning argues that carbon credits should not be treated as equivalent to compliance under the EU Emissions Trading System (EU ETS), the bloc’s internal carbon market. Inside the EU ETS framework, industrial producers such as steel, cement, aluminium, fertiliser and chemical companies must surrender allowances strictly aligned with verified emissions. They cannot use offset credits to replace that obligation.
Allowing exporters from outside the EU to reduce CBAM exposure using carbon credits, the groups argue, would introduce a structural imbalance between European producers and foreign competitors. This, they say, contradicts the original purpose of CBAM.
CBAM’s design goal: equalising carbon costs
The CBAM framework, linked directly to the EU ETS, is designed to prevent carbon leakage by ensuring that imported goods face a comparable carbon cost to those produced within the EU. As free allowances under the ETS are gradually phased out, CBAM is meant to maintain competitiveness while preserving climate ambition For that system to function credibly, the carbon cost applied to imports must closely mirror the discipline imposed on EU-based industries.
Industry representatives argue that carbon credits fail that test.
Unlike emissions trading allowances, credits often represent avoided emissions, offsets, or external projects rather than direct reductions at the emitting facility. This, they say, weakens the incentive for industrial decarbonisation at the source and introduces variability in how carbon costs are measured and verified.
The regulatory asymmetry problem
A key concern raised in the submission to the Commission’s tax department (DG TAXUD) is regulatory symmetry. European producers cannot offset emissions obligations under the EU ETS with external credits. If non-EU exporters are allowed to do so under CBAM calculations, it could create what industry groups describe as an uneven competitive field.
Sectors most affected include carbon-intensive industries already covered by CBAM, such as:
- Steel and iron production
- Aluminium manufacturing
- Cement and construction materials
- Fertilisers
- Hydrogen and electricity-related products
These sectors are capital-heavy, energy-intensive, and already under pressure to decarbonise through electrification, hydrogen adoption, carbon capture, efficiency improvements, and renewable energy sourcing. Industry groups argue that weakening CBAM through credit offsets would dilute the carbon price signal intended to drive these investments.
Concern over policy loopholes and market distortion
The Commission’s draft rules reportedly allow recognition of both domestic and international carbon credits, provided proof of payment exists. While international credits would be subject to additional safeguards, domestic credits appear to face fewer constraints beyond verification.
Critics warn that this distinction could open the door to uneven standards across jurisdictions. A carbon credit system does not necessarily impose the same operational requirements as emissions trading systems, where emitters must directly account for each tonne of CO₂ produced.
This difference matters because it affects industrial behaviour. Credits can be purchased externally, while emissions trading requires internal reductions or the purchase of capped allowances. Industry groups argue that the latter drives stronger decarbonisation outcomes.
Legal and institutional tensions
The debate is also tied to broader questions about EU legislative procedure. Some stakeholders argue that recognising carbon credits through secondary implementing legislation risks bypassing a wider political discussion already underway in the European Parliament and Council regarding Article 6 mechanisms under the Paris Agreement. This raises concerns that fundamental design choices for CBAM could be settled at technical level before lawmakers fully define the long-term framework.
CBAM is still in its transitional phase, where companies report emissions data without yet paying full financial adjustments. Once the system becomes fully operational, the financial impact on importers will be significant, making today’s technical definitions highly consequential for future trade flows.
Impact on global supply chains
Beyond Europe, the outcome of this debate will affect exporters in regions such as the Western Balkans, Turkey, North Africa, and parts of Asia that supply carbon-intensive goods into the EU market. CBAM is already pushing exporters to improve emissions monitoring, adopt verified reporting systems, and invest in cleaner production processes. Steel mills, cement plants, and aluminium smelters exporting to Europe are increasingly required to document embedded emissions, energy sources, and production methods in detail. Industry groups warn that allowing carbon credits to reduce CBAM liabilities could shift incentives away from real industrial upgrades and toward financial compliance mechanisms. Instead of investing in cleaner production, some exporters might rely more heavily on purchasing credits to reduce costs. This, they argue, could weaken CBAM’s intended role as a driver of global industrial decarbonisation.
Policy dilemma: flexibility versus credibility
The European Commission now faces a difficult balancing act. A flexible approach to carbon credits could ease implementation pressure and reduce friction with trading partners. It might also lower compliance costs in the early stages of CBAM rollout.
Stricter rules excluding credits would preserve closer alignment with the EU ETS and strengthen the environmental integrity of the system. It would also reinforce incentives for genuine emissions reductions rather than financial offsets. The coalition’s position is clear: only carbon pricing instruments that impose obligations equivalent to the EU ETS should be eligible for CBAM deductions. Both domestic and international carbon credits, they argue, should be excluded.
A defining test for CBAM’s credibility
The outcome of this debate will shape how CBAM is perceived globally. If designed too loosely, the mechanism risks creating gaps between EU producers bound by strict emissions obligations and foreign exporters operating under more flexible systems. If designed too strictly, it could increase trade tensions but preserve environmental integrity and industrial competitiveness within Europe.
At its core, CBAM is meant to make carbon costs visible in global trade flows. Its effectiveness depends on whether those costs reflect real industrial emissions or can be reduced through financial instruments that the EU itself does not recognise within its own carbon market.
The current dispute suggests that the EU is entering a critical phase: moving from designing climate policy architecture to defining the precise economic rules that will determine how global industry responds to it.
