UK government accused of pursuing 'gimmicks' to tackle air pollution

Green lawyers criticise government after it emerged experts were commissioned to explore whether high-tech paint could reduce NO2 levels

Lawyers have accused the government of pursuing gimmicks to tackle illegal air pollution, after it emerged experts were asked to examine whether high-tech paint could fix the problem.

After losing a legal battle over pollution in the supreme court last year, the environment department last year announced plans for five clean air zones which will not affect nine in 10 vehicles.
