Pollution cameras, funded by the Department for Transport, have been installed on two of London's busiest roads to measure emissions emitted from vehicles, as air pollution in London regularly exceeds the EU safety limits. The camera trial will look at the difference between real world emissions and the laboratory test emissions, carried out on cars before they go on sale. The cameras use laser beams which shine through exhaust fumes, and reflected light allows scientists to analyse the type and amount of pollution that is released from each vehicle, whilst a separate camera records the number plate. Transport minister, Jonathan Isaby said "We are pleased to support important work that improves our understanding of the impact that vehicle emissions have on air quality levels."
