A year-long survey will be carried out in the capital.
London's pollution levels will be monitored from next month, with two Google StreetView cars mapping the capital also recording air quality
The cars will take readings every 30 metres to record the air quality in the city, and there will be 100 fixed sensors fitted to lampposts and buildings in so-called pollution black spots across the city, creating what mayor Sadiq Khan is calling 'the most sophisticated [air quality monitoring system] in the world'.
The whole project will last a year, and will generate hyperlocal data to aid policy responses. It is being undertaken in partnership between the Greater London Authority and C40 Cities network – a group of cities across the world focused on tackling climate change.
Environmental Defense Fund Europe, Air Monitors, Google Earth Outreach, Cambridge Environmental Research Consultants, University of Cambridge, National Physical Laboratory, and the Environmental Defense Fund team in the United States are all working together on the project, while King’s College London will also be undertaking its own linked study, but focussing on schools.
The results will be shared with members of the C40 Cities network in order to assist with their own policy responses and climate change initiatives, in the hope that more cities will be able to reduce pollution levels.
