The European Union proposed stricter emissions rules for the continent’s last generation of combustion engines, a move aimed at reducing particulate pollution in the continent’s cities.
The bloc said the new rules for the so-called Euro-7 generation of engines would further reduce by about a quarter the amount of nitrous oxides that diesel engines can emit.
Nitrous oxides can damage the human respiratory tract, worsening conditions like lung infections and asthma and potentially causing chronic lung disease.
“Road transport is the largest source of air pollution in cities,” the EU said in a statement, adding that the new regulations will lead to a third less nitrous oxide emitted by 2035 than current rules allow.
“The new Euro 7 standards will ensure cleaner vehicles on our roads and improve air quality, protecting the health of our citizens and the environment.”
Adoption of the rules, which requires approval from member states and the European Parliament, has been delayed several times amid wrangling over their contents.
Automotive executives including Carlos Tavares, chief executive officer of Stellantis NV, have argued the latest steps pose unnecessary burdens on the car industry and will slow the sector’s shift to electrification.
Nitrous-oxide emissions for gasoline engines will remain the same, allowing them to emit 60 milligrams for every kilometer traveled. Diesel engines will also be restricted to that level, a more stringent rule than the 80 milligrams of nitrous oxides allowed under Euro-6 rules.
The proposed rules also set limits for particulate emissions from brakes and tires that will also apply to electric vehicles.
Studies have shown brake wear is one of the biggest sources of non-exhaust road traffic emissions in urban areas.
Supporters of the rules argue that some vehicles going on sale between 2025 and 2035 will be sold in the second-hand market and run on the roads for decades.
That means more stringent rules on particulate pollution could end up saving thousands of lives, they say.
The rules, part of the European Green Deal aimed at putting the continent’s economy on a sustainable footing, will develop stricter emissions standards for all gasoline and diesel cars, vans, trucks, and buses.
The bloc reached a landmark deal last month to effectively ban new combustion-engine cars from 2035, forcing companies to overhaul their lineups.
The push poses risks to employment and vehicle affordability, EU Internal Market Commissioner Thierry Breton said last week, a signal that a delay in the policy may be possible in 2026.
