Automakers, represented by the European Automobile Manufacturers' Association (ACEA), have been pushing for a further delay to these rules, which have already been postponed by three years. However, an analysis by Transport & Environment (T&E) debunks the industry's claims and supports the implementation of the existing regulations.

T&E's findings indicate that EU battery production capacity will significantly exceed the demand required for EU-UK trade in 2027. For nickel-rich NMC batteries, EU production is projected to be six times the amount needed for exports to the UK, and for lithium-iron phosphate (LFP) batteries, it will be 2.4 times the requirement.

Furthermore, the analysis shows sufficient cathode active material (CAM) production within the EU to meet the demand for EU-built EVs exported to the UK. EU CAM supply is expected to surpass the needs for both NMC and LFP batteries by over a third, and by nearly five times for NCA batteries.

Implementing these rules is considered vital for securing Europe's battery value chain and maintaining investor confidence. EU Trade Commissioner Maroš Šefčovič has previously stated that the Commission would introduce a mechanism to prevent further extensions beyond 2032, emphasizing the need for the permanent TCA rules of origin to apply as scheduled.
