The European Automobile Manufacturers’ Association (ACEA) has released its 2023 Regulatory Guide, providing an in-depth look at both national and international regulations affecting the automotive industry. This guide is an essential resource for understanding the current regulatory framework and its implications for COCs​​ [”].

A notable development is the 'Fit for 55' regulation adopted by the Council, focusing on reducing emissions from road transport. As the transport sector leads in emissions, this regulation is pivotal in encouraging a shift towards zero-emission vehicles while fostering innovation. This move will significantly influence the standards for COCs, emphasizing environmental compliance [”]​​.

The United Nations Economic Commission for Europe (UNECE) has introduced regulations R166 and R167 at the World Forum for Harmonization of Vehicle Regulations. These regulations concentrate on vehicles in categories M1 and N1, particularly concerning the safety of vulnerable road users. COC issuers and applicants must be aware of these changes to ensure compliance and safety standards [”]​​.

There has been a recent development where the EU's pollution rules for combustion engine cars and trucks have been moderated. Originally planned to be more stringent, these rules have now been delayed and softened, impacting the criteria under which COCs are issued [”]​​.

The European Commission has adopted a proposal to implement circularity requirements in vehicle design and management of end-of-life vehicles. This regulation includes aspects like reusability, recyclability, and recoverability, along with the use of recycled content. Such measures are essential in defining the environmental aspect of COCs, reflecting a more sustainable approach in the automotive industry [”]​​.
