The EU CBAM Omnibus reforms have been published on 17 October 2025 on the Official Journal of the European Union (OJEU). The changes will enter into force on the third day following its publication.

EU Commits to support developing countries impacted by CBAM

In its joint communication EU global climate and energy vision: securing Europe's competitive role in world markets and accelerating the clean transition, the Commission highlights that while CBAM won't be rolled back, they will support developing economies impacted by the EU CBAM in their decarbonisation efforts.

While CBAM gradually enters into application, we intend to maximise the contribution of Global Europe to developing countries' decarbonisation and adaptation needs, in line with the instrument’s 30% climate and environment spending target. This would help alleviate concerns raised on EU legislation as well as strengthen partnerships and support broader regulatory reforms. To this end, we will also mobilise EU Member States’ expertise as well as targeted use of Technical Assistance and Information Exchange (TAIEX) for the clean transition.
