Remote sensing of motor vehicle emissions in Paris
In 2017, Mayor Anne Hidalgo of Paris and Mayor Saddiq Khan of London jointly committed to making data on real-world vehicle pollutant emissions available to residents of those cities. In support of that aim, The Real Urban Emissions Initiative (TRUE) commissioned in-use vehicle testing campaigns in both cities, to be carried out using remote sensing technology. In summer 2018, TRUE measured emissions from more than 180,000 vehicles on the road at three Paris sites. A newly published paper reports the results.
