Tougher new emission tests for new car models before they can be driven on European roads come into force today.
The process, called Real Driving Emissions (RDE), will determine whether new diesel car models are allowed to be put on the market.
It follows the Volkswagen scandal when the car manufacturer pleaded guilty to using a software that deceived emissions testing for certain air pollutants.
The new RDE model is designed to reflect everyday driving conditions and ensure more reliable results.
NOx and particulate emissions, which are a major cause of air pollution, will be measured in real driving conditions, complementing a new, “more realistic” laboratory test for all emissions, including CO2 and fuel usage as well as NOx and other air pollutants.
Both tests are now mandatory for all new car models and will be phased in for all new cars between 2018/19.
Commissioner Elżbieta Bieńkowska, responsible for Internal Market, Industry, Entrepreneurship and SMEs said: “A quick shift to zero emissions vehicles is in all our interest given the public health and environmental risks at stake. And it’s crucial for the car industry if it wants to remain internationally competitive.
“But for the time being, diesel cars remain part of our lives and we must rebuild confidence in this technology. That is why having new and more reliable tests for new cars is essential. And for cars already on the road, Member States must do their job, enforce the law and take additional steps, together with all stakeholders, to bring down emissions of the existing fleet.”
