Air pollution information

We all know air pollution in London is bad but how bad is it exactly where we live? 

To find out what the situation is exactly in our part of North West London, Transition Kensal to Kilburn and Transition Willesden carried out an air pollution monitoring project in 2016 (click here for results). 

If you want to find out what the quality of the air is in North West London nowadays, you can check the Breathe London website. 

You can click on the different air pollution monitoring stations located in the area and find out what the levels of particulate matter (PM 2.5) and nitrogen dioxide (NO2) are.

Six years since TTKK measured air pollution in the area, the air quality in our part of North West London remains poor. However, since October 2021, Brent south is covered by the Ultra Low Emission Zone (ULEZ). That has led to a 20% drop in NO2 across the expanded ULEZ zone, according to a report published by the Mayor of London in July 2022. 

If you want to receive regular updates about air pollution news for Brent and London and/or want to share articles and other bits of information about air pollution please join this group.

Here are the results of our pollution monitoring TTK2K map.  As you can see all but two of our sites are over the EU legal limit for nitrogen dioxide (NO2) and Kilburn High Road is nearly twice the limit

And here are the results for Transition Willesden TW map 1 and TW map 2  Seven of our 10 sites were above the EU legal limit for NO2, with Cricklewood Broadway being over twice the limit.

In all 75% of the 20 sites tested exceeded legal limits for the pollutant.

We met in mid January along with other community groups to decide on actions to follow up this and combat pollution in our area. Watch this space for how to get involved.

Great start to our project on Saturday with a wonderful group of volunteers putting ten nitrogen dioxide monitoring tubes out round the TTKK area.  Watch this space for a map of where they are located.  We also tested for particulates in four areas.  Results to follow next month.

We held our first meeting on Wednesday evening as planned.

Members of several residents association (Brent Eleven Streets, Kensal Rise Residents Association and Kensal Triangle Residents Association) were there.

We are planning to kick start the air monitoring at the very beginning of September but that needs confirming. 

When a date has been confirmed, we will put a message out for volunteers. We will need people to attach diffusion tubes to lamp posts and take them down a month later.
