Good morning, this is Paula. A UN commission decided this week that it was the end of the road for one of the biggest sources of microplastic pollution. Invisible particles shed from tyres as vehicles make tracks, ending up in the most pristine of habitats, washing into lakes and rivers, and blowing into the air.

My colleague, Michelle, reports on what the new regulations will mean once they are adopted at a conference here in June.

Every move you make, every turn you take, every time you brake, every time you accelerate – your tyres will be shedding microplastics. Tyre and road wear particles – as the specialists call it – are an invisible, lesser-known source of plastic pollution. Part natural and part synthetic rubber, a plastic polymer, tyres lose about a third of their weight over their lifetime, polluting the air, water and soil.

Now, a new regulation under discussion in Geneva wants to curb that. This week, the UN Economic Commission for Europe (UNECE) adopted limits on tyre abrasions from new C1 tyres for cars and vans.

Studies have shown tyre wear is one of the largest sources of microplastics in the environment, making up 78 per cent of 1.3 million metric tons of microplastics leaking into the ocean in 2016 – a figure on track to more than double by 2040.
