Norwood Air Quality Experiment

Green Town Plan: Air Quality Citizens Science Experiment – the results are in

As part of our evidence gathering to support our emerging Green Town Plan policies on air pollution, we conducted a “citizens science experiment” to measure levels of Nitrous Oxide around our Neighbourhood.

The results are now in and shown in the attached map and spreadsheet.

The survey was conducted between 8thand 22ndMay at 15 locations across Norwood. This included a mix of main traffic routes, residential streets and Norwood Park.

The results demonstrate potential illegal levels of Nitrous Oxide along main roads within Norwood including Knights Hill, Norwood Road, the Tulse Hill Gyratory and Thurlow Park Road.

While there would need to be a much longer period of monitoring to be conclusive, they do show that there is a potential big issue with air pollution in the area, and should help frame our policies and arguments – not least lobbying the Council and TfL to help make improvements to our neighbourhood.

The Citizens Science Experiment is part of a wider initiative by London Sustainability Exchange. For more information go to:
