In November 2022, the European Commission (EC) published its impact assessment (IA) for Euro 7, which included three policy options for the standard’s prospective succession of Euro 6/VI. Each was considered either low, medium, or high ambition according to its relative complexity, cost, and projected benefits.
Low ambition for Euro 7 gasoline cars, for example, was almost identical to Euro 6 aside from slightly more stringent carbon monoxide limits (1,000mg/km to 500mg/km). Meanwhile, the high ambition lowered every limit (nitrogen oxides, particle number, particulate mass, etc.) by around 50-66%. The IA ultimately concluded that a balanced approach between these extremes (medium ambition) would deliver the best health and environmental benefits while also being the most cost-effective for the automotive industry.
