Heavier new cars pump out MORE CO2 than older models despite motor industry claims that the vehicles are better for the environment

Larger new cars are ‘less green’ than older vehicles, despite motor industry claims they are backing efforts to combat global warming.

Consumer experts at Which? found the latest generation of cars emit more CO2, which is associated with climate change.

This is largely because new vehicles in almost every category tend to be heavier than their predecessors.

Ironically, one of the reasons they weigh more is because manufacturers have installed new devices to cut exhaust emissions that are harmful to human health, such as nitrogen dioxide.

The findings suggest manufacturers making conventional internal combustion engine vehicles are fuelling global warming, and the evidence will be seized on by those supporting the Government’s plan to ban the sale of new petrol and diesel cars by 2035, or potentially sooner.

The consumer group looked at the 292 car models it has tested since the start of 2017.

This shows an average increase in CO2 of 10.5g/km (7 per cent) – from 151.6g/km to 162.1g/km.

It said cars which meet the latest emission regulations – Euro 6d-temp and Euro 6d – generally produced more CO2 than vehicles certified under the previous emission regulations – Euro 6b and Euro 6c.

The small petrol cars category, which covers those the size of a Ford Fiesta or Volkswagen Polo, saw an average increase of 11.2 per cent – up from 131g/km to 145.7g.
