EU Emissions Compliance Regulation Gaining Traction

Historically, the emissions standards for mobile sources promulgated by the U.S. Environmental Protection Agency (EPA) have been viewed as more ambitious than European Union (EU) standards. The United States’ stringent enforcement of mobile source emission standards may result in significant financial penalties; extensive injunctive relief, such as recalls and high-cost mitigation projects; corporate compliance requirements; and in some cases, criminal indictment.

On the other side of the Atlantic, in the EU, mobile emissions compliance regulations are becoming more robust. In particular, the EU appears to be adopting a stricter approach on emissions through a growing body of case law on the interpretation and application of existing emissions compliance regulations. In a judgment on 17 December 2020, in CLCV and Others, the Court of Justice of the European Union (Court) adopted a potentially broad interpretation on the definition of defeat devices and appeared to limit the scope of exceptions for their use in vehicles sold, registered, or put into service in the EU.1 This judgment is likely to set the benchmark for other proceedings on the admissibility of defeat devices in the EU.

Notably, there are at least six cases pending before the Court on mobile source emissions and the concept of defeat devices for light-duty passenger and commercial vehicles under Regulation (EC) No 715/2007 (Regulation).2
