Traffic calming measures could ‘damage the environment’

The AA fears that the growth of 20mph zones could be environmentally damaging, according to an article in the Daily Telegraph this week.

According to Edmund King, president of the organisation, carbon emissions are likely to be higher at lower speeds because cars are normally driven in a lower gear, and higher revs pump out more emissions as the engine works harder.

Mr King is quoted as saying: “If we are smart about urban transport we can reduce CO₂ and congestion without spending millions. Congestion and CO₂ can be reduced by improving traffic flow through co-ordination of road works, phasing of lights and good parking policy,” he said.

Public support for 20mph zones

A spokesperson for the Environmental Transport Association (ETA) said: “Improved traffic flow can help reduce pollution, but the AA appears out of touch on the issue of 20mph zones – people simply don’t want to put up any longer with cars travelling at high speeds on the streets where they live and their children go to school and play – 20mph zones encourage walking, cycling and a generally better quality of life and that’s why they are environmentally friendly.
