Measuring Londoner’ Daily Exposure to Air Pollution March 10, 2019 / activist360 / Leave a comment The Mayor of London, Environmental Defense Fund, C40 (an international consortium of 90 cities tackling climate change), and a host of partners launched Breathe London, an ambitious project that will measure and map Londoners’ daily exposure to air pollution using a network of advanced air pollution sensors deployed across the city. Breathe London will shine a spotlight on air pollution at a hyper-local level and provide data that lets us not only see the problem, but take action to solve it.
