Help us test Hampstead’s air quality

Polluted air in central London

In 2015 we measured nitrogen dioxide (NO2) levels in the Forum area. The level of pollution we found in leafy Hampstead, and members’ reaction to it, inspired many of the policies in the Neighbourhood Plan you approved by referendum in 2018. This year, we are returning to this issue with a new project that will measure both NO2 and particulate levels in Hampstead.

NO2 again

We will return to the NO2 measuring sites to find out what has changed. Unlike our earlier project, this time we are being advised by Camden’s own Air Quality officer. The survey will run all year, and the readings we collect will be reference quality, fit to stand with Camden’s official figures. We will be able to tell whether we on track to get inside WHO-recommended limits by 2030, or if more action is needed?

For this part of the project we need £2,000 to buy, mount and process the diffusion tubes used to measure NO2 levels. Five years ago, you backed the survey vigorously. Please do so again!


Neighbourhood particulates

The school run

Everyone knows Hampstead’s air is polluted by the school run, but no one knows by how much – nor how much Camden‘s Healthy School Streets programme is helping. Once the NO2 survey is funded we want to buy a particulates monitor. This is new work. In 2015 we were able to measure only NO2 pollution, not the dangerous microscopic particles that drift from car brakes and tyres into children’s lungs and arteries.

Over 2021, once the school run has resumed, we plan to record an hour-by-hour particulates pollution profile near each school in the Forum area. The readings will demonstrate that all is well – or will provide a factual basis for action. Static particulate monitors are expensive, but £5,000 will buy a monitor that produces “near-reference” quality readings on which Camden can base policy. Please give generously!
