Pipeline emissions tend to be the focus of regulators, but the next round of European Union emissions standards will tackle pollution from another source — one particularly related to vehicles. electricity.
Expected to be published in July, the upcoming Euro 7 standard will still require carmakers to reduce exhaust emissions such as nitrogen oxides. But they will also put a limit on brake dust, according to Euractiv.

Yes, electric cars don’t use friction brakes as much as internal combustion cars. That’s thanks to regenerative braking. But like a recent study In conclusion, that’s not enough to offset the higher weight of the EV battery packs.
The European Commission (the EU’s governing body) has announced its intention to regulate brake dust within a year Policy plan for 2021says it will address particulate emissions that are “same from both conventional and electric vehicles.”
A recent (and controversial) study found that electric vehicles also help increase tire-related particulate emissions—Great due to the extra weight of the battery pack. But these emissions are not the target of EU regulators right now.

It’s not clear how automakers will reduce brake dust. A recent concept from Stellantis’ DS Automobiles, drawn from the Formula E experience, hints at how EVs in the future friction pads can be completely ignored.
Active regenerative braking allows today’s electric vehicle drivers to use less frictional braking — generating less dust and allows brake pads to last longer.
However, not all automakers agree on the merits of single-pedal driving modes. Porsche deliberately avoids driving with one pedal on Taycanclaims that its automated regeneration strategy — and longer duration — will be more effective overall.
