Road transport emissions up since 1990 despite efficiency drive

ONS says rise is result of growing traffic as campaigners say car use must be curbed

Britain's greenhouse gas emissions from road transport have continued to grow since 1990 despite more efficient cars because traffic has increased by almost a third, according to government figures.

Cutting emissions on Britain's roads remains a significant challenge, according to the report from the Office for National Statistics, citing a 6% rise in greenhouse gases in the past three decades.
