For brakes at least, electric vehicles should permit brake emmisions to be reduced significantly. First, you've got regenerative braking, so no real need to use friction brakes except when braking too hard for regen. But as you've got a good supply of electricity, most of the rest of braking could be handled by the combination of an induction brake [0] and actively powering the motors in reverse, perhaps leaving friction brakes just for emergencies.
This is what EVs do. Even pressing the brake pedal doesn't directly engage the actual brakes, it'll first use the engine regen to slow down and if that's not enough the brakes will start applying.
I actually need to put my car on neutral while driving and press the brakes properly about once a month so they don't rust from lack of use :D
Meanwhile in the United States, even liberal environmentally-minded folks think buying a F-150 Lightning is reasonable to go to work and the grocery store.
Then charge your bike and go for a ride. Save $40k(?) You’ll run over and kill less people, be less fat, emit less rubber from tires into water runoff (yummy!) and it’s not like batteries are being charged from renewables in most places.
Yeah sure that might work for some but not for all. There are legitimate reasons to need something other than a bike and I would expect those that made the choice weighed their options before spending that amount of money. Likewise all the benefits of bikes are legitimate as well.
Unreasonable maybe yes maybe no it’s difficult to know what an individual factors into a decision.
Any kind of rolling road is sure to make large numbers of particles itself. Besides - most tyre particles are emitted when going round corners and accelerating hard to cause wheel slip, which can't be done on a rolling road.
Or they do it on a real road - but how many particles will come from the tyres and brakes, and how many will come from the road itself or other pollution sources?
> The Commission should prepare a report on tyre abrasion by the end of 2024 to
review the measurement methods and state-of-the-art in order to propose tyre abrasion limits by December 2025 at the latest, should the work on tyre abrasion done at UN WP 29 be delayed.
this document isn't them saying "this is how we're going to do it", it's saying "this is what we're going to do".
For anyone who lives in a city... I'd suggest getting an air filter - any pollen/HEPA filter will do a good job of de-dusting your house. Just a $20 unit from Amazon will do - put it in a hallway and it will get most of your house air as long as you don't keep external windows wide open.
As well as keeping your indoor air cleaner, you'll also find that you have to clean dust off surfaces less frequently. I suspect there are big health benefits too, but can't prove that.
After a few months, the filter turns from white to dark grey, but I've found it keeps working for even years after that - you would expect it to get full and get blocked, but I guess tiny particles take a real long time to block it.
There are machines designed for testing tires and axles that go around corners under load- for example, the fatigue carousel at University Gustave Eiffel, currently used to test pavement. I could imagine such a machine rolling tires in a closed environment and comparing to reference data. https://lames.univ-gustave-eiffel.fr/en/equipments/the-pavem...
NGO has some serious complaints about last minute car manufactures lobbying [0]
Another NGO has a nice table comparing Euro 7 with Euro 6, China & US [1]
surveillance or on-board monitoring (OBM) of emissions at all times and for the lifetime of a vehicle has been discussed but was not removed [2], “With a multitude of factors determining the actual emissions behavior of the application as well as the measuring accuracy, meeting the intended continuous emissions monitoring represents … the dominating challenge” “the vehicles receive an overall budget for all trips up to 16 km distance” [3]
Euro 7 Minimum performance requirements for battery durability, see Annex II in [4]
80% for first 100.000 km or 5 years
70% for first 180.000 km or 8 years
The original pre-rename title of this HN post is more relevant (I understand HN’s guidelines on title-jacking, but still this is relevant): “EU’s Euro 7 will also consider tyre and brake particle emissions”.
