Perhaps it’s mostly existing particles laying on the road that are thrown up by the next vehicle’s tyres as it passes?

That's a pretty long stretch from the claim: "we found that the car emitted 5.8 grams per kilometer of particles".

But is it a long stretch from the claim: "Non-exhaust emissions (NEE) are particles released into the air from brake wear, tyre wear, road surface wear and resuspension of road dust during on-road vehicle usage."

Resuspension of road dust is literally one of the 4 things they defined as the NEE they're measuring.

OK, I missed that bit.

But counting "resuspended road dust" as "emissions" seems pretty far fetched to me. Especially if that's a significant portion of the "5.8 grams per kilometer of particles", and you then push out a press release with the hyperbolic headline claim "Pollution from tire wear 1000 times worse than exhaust emissions."

And they then have the audacity to claim: "Emissions Analytics seeks to bring transparency to a confused market sector."

Pretty sure I know who's funding them now, without even bothering to google it...

Who's funding them? Radical balloonists? Big Rail? Maybe it's the Hovercraft Lobby! I never did trust them.

Fossil fuel industry.

(But if it _is_ the Hovercraft Lobby, I'm totally in!)
