Gregory's ServerSome 2 billion tyres are made a year. 78% of microplastics in the ocean come from tyres. Car tyres are made from around 24% synthetic rubber. This “chemical cocktail” of 400 chemicals includes heavy metals like copper, lead and zinc. A reduction of tyre wear particles is as important as reducing exhaust emissions.

Not alone do we already have too many cars, some predict we may go from 1.4 billion to 2.5 billion in the next 20-30 years. So, we'll have lots of electric cars and lots of petrol and diesel cars.
We are breaching multiple boundaries for a safe environment. We must address the problem of overconsumption and its impacts on soil, air and water. Focusing on just one metric such as CO2 will do greater total damage. We must have a basket of metrics covering air, water and soil.
