Deft landing, captain

Euro 7 has finally arrived - As the saying goes, a ‘good’ landing is one from which you can walk away, but a ‘great’ landing is one after which they can use the plane again. Euro 7 has not just landed safely, but the craft that is the European system of emissions regulation remains viable. It required a deft touch. The industry says it is too tough and environmental campaigners say it is too weak in equal measure, which perhaps reflects the achievement.

Following the tyre tracks… Where do tyre emissions go?

Following the tyre tracks… Where do tyre emissions go?

We know, from earlier research, that tyres emit lots of particles, both coarser and the more potentially dangerous ultrafines. To put this in context, the levels are less than from exhausts of many older diesel vehicles without filters, but orders of magnitude greater than from the exhausts of modern internal combustion engine vehicles with the latest filters. But, where do these particles go, and can they be found in the environment?

The evidence clearly points to using full hybrid electric vehicles (FHEVs) as the best route to rapid, low-risk decarbonisation of cars and vans for the next decade. FHEVs cannot deliver the biggest aggregate reduction in principle, but with scarce battery resources and higher manufacturing carbon dioxide (CO2) emissions of battery electric vehicles (BEV), FHEVs can deliver more CO2 reduction now, and potentially for some time to come.

By some distance, the research Emissions Analytics published in early 2020 claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions generated the most feedback of any subject we have tackled so far – feedback that was a mixture of surprise and scepticism

That’s 1,000,000,000,000,000,000,000,000 exhaust emissions particles that are due to be emitted in the United States that don’t need to be. How? A large majority of European and Chinese cars are now sold with tailpipe particle filters, known as gasoline particulate filters (GPFs) or diesel particulate filters (DPFs) in the industry, but this is not the case in the US.
