Effective
Ensure exposure of individual citizens to vehicle pollution is within safe limits
Towards zero‐impact on air quality with specific attention to urban environment
Real‐world
Legislate actual tailpipe emissions
No more data exclusion and normalisation
Neutral
Fuel‐ & technology‐neutral procedures and limits
Application‐neutral with similar stringency for every type of vehicle and machine
General legislative principles to enhance real‐world compliance
AGVES meeting – 18 October 2019 8
To build further on success of RDE in Euro 6d for the next step in emission legislation
