EU tightens carbon border tax rules for 2026

December 04, 2025

European Union lawmakers have backed a plan to tighten enforcement of goods entering the EU under the bloc’s carbon border tax, following a decisive vote in the European Parliament’s environment committee on Wednesday.

Beginning in January 2026, the Carbon Border Adjustment Mechanism (CBAM) will officially enter its charging phase, requiring companies to pay for the greenhouse gas emissions linked to imported products—including steel, aluminium, cement and fertilisers.

With new oversight rules expected to be presented soon by the European Commission, lawmakers voted 68 to 7 in favor of fast-tracking legislation aimed at improving monitoring and compliance.

Creating a level playing field for EU industry

CBAM is designed to protect European manufacturers who already comply with emissions regulations under the EU Emissions Trading System (ETS). By applying a carbon price to imports, EU officials aim to prevent carbon leakage and encourage global industries to adopt cleaner production standards.

However, the initiative has drawn criticism from the United States, which argues that the EU carbon border tax could act as a trade barrier for foreign companies.

New CBAM rules to crack down on carbon evasion

On December 10, the Commission is expected to introduce new rules establishing standardized CO₂ values for each country or exporting company. The goal is to close loopholes that could allow importers to bypass taxation.

According to a leaked document obtained by Euronews:

• In 2026, on-site inspections will be required at facilities producing CBAM-regulated goods.

• From 2027, inspections may shift to virtual verification or be waived if sites qualify as low-risk and provide consistent emissions data.

• Importers will be permitted a 5% margin of error in emissions reporting before their data is considered unreliable.

• EU regulators also intend to better synchronize CBAM with the ETS to ensure regulatory consistency across the market.

CBAM simplification aims to ease administrative pressure

The Commission introduced CBAM simplification measures in February 2024, building on legislation first passed in April 2023. In September, lawmakers approved a new exemption for companies producing less than 50 tonnes of CBAM-covered products per year.

This update replaces the previous €150-per-shipment threshold and is expected to remove roughly 182,000 importers from the reporting system, largely benefiting small businesses. Despite this shift, more than 99% of emissions will remain subject to the carbon levy.

For companies that stay within CBAM scope, the changes will:

• Reduce paperwork and administrative burdens

• Simplify emissions calculations and reporting rules

• Speed up authorization and reduce compliance costs

By 2027, the Commission may also publish default carbon prices for third-country markets, improving transparency for importers and regulators.

Industry reaction: automotive sector calls for clarity

The European Automobile Manufacturers’ Association (ACEA) has urged the Commission to accelerate guidance on CBAM implementation. The automotive sector relies heavily on imported aluminium and steel—materials central to CBAM compliance.

ACEA Director General Sigrid de Vries acknowledged that automakers are prepared to support the mechanism but warned that unresolved regulatory gaps threaten the 2026 launch.

 “There are still too many unanswered questions this late in the process, making proper implementation by 1 January 2026 nearly unachievable,” de Vries stated.

Conclusion

The EU’s strengthened carbon border tax is set to reshape global trade dynamics by linking import costs to emissions performance. While policymakers hope CBAM will motivate international decarbonization, industry groups are urging Brussels to deliver clear guidance to prevent disruption as the system moves toward full enforcement in 2026.
