Reducing carbon dioxide emissions from passenger cars : finally picking up pace, but challenges on the road ahead; Special report 01, 2024

As of 2020, 11 years after the first Cars CO₂ Regulation entered into force, CO₂ emissions from new passenger cars began to drop significantly. This was mainly due to a significant uptake of electric vehicles, while real-world CO₂ emissions from cars with combustion engines have not dropped. Although the Commission collected and verified the car CO₂ emissions data in line with the Regulation, there is insufficient assurance on the accuracy of CO₂ emissions declared by manufacturers on new car certificates of conformity. We recommend the Commission make better use of electronic tools for collecting and verifying car data and refocus the CO₂ emission reduction targets to address key elements that affect CO₂ emissions from new passenger cars.
