The UK has started trialling special pollution-measuring lasers, which are designed to analyse the emissions spewed out by cars in real-world driving conditions. They’re currently being tested on roads in London and Birmingham, with the project being funded by the Department for Transport (DfT).
Many cars are believed to burn through more fuel than manufacturers claim, which makes it impossible to know how much pollution they produce. However, EDAR’s laser system, which is able to identify each vehicle it comes across, uses the light reflected back off exhaust fumes to measure toxin levels.
All data is currently anonymous, but researchers at the University of Birmingham, the University of Leeds and KCL will analyse it for use in a DfT report, which will come out later in the year. [BBC]
