Camden makes progress on cleaner air for all
Camden Council has now released its air quality Annual Status Report for 2024, with the latest monitoring data showing a continuing trend of air quality improvements in Camden.
Confirmed and ratified data for 2024 show that nitrogen dioxide (NO2) air pollution concentrations were on average ten percent lower across Camden’s automatic monitoring portfolio than in 2020, when the effects of the COVID pandemic resulted in significantly reduced motor traffic.
Whilst great progress has been made to clean London’s air, air pollution is still the largest environmental threat to public health in the UK and so it is crucial that the impacts of air pollution and how to reduce your exposure to it are widely understood.
The Royal College of Physicians’ (RCP) a Breath of Fresh Air report highlight the issues still posed by poor air quality. The report highlights new evidence confirming the link between air pollution and almost every organ in the body and the diseases that affect them, with “30,000 deaths per year in the UK estimated to be attributed to air pollution, with an economic cost of £27 billion in the UK due to healthcare costs, productivity losses and reduced quality of life.”
We were the first local authority to commit to achieving the updated World Health Organization air quality guidelines and are working with our communities and partners in the borough and beyond to reduce sources of air pollution down as quickly as possible.
Our Clean Air Action Plan 2023-2026, sets out our ambitious air quality programme to realise the vision for a borough with clean air.
Our Plan seeks to tackle the local sources of NO2 and particulate matter air pollution whilst also helping to build public awareness as well as also advocating for action and ambition in national policy, to help to control pollution sources outside of Camden’s boundaries.
Air quality progress in Camden
By the end 2024, we measured nitrogen dioxide (NO2) air pollution at 321 diffusion tube sites and four automatic sites. The 40 microgram per cubic metre (µg/m3) national legal limit for NO2 was met at all but three of our monitoring locations in the borough; two of these non-compliant sites were along Euston Road and the other on Shaftesbury Avenue.
In 2018 – the year before the introduction of the ULEZ scheme – 98 out of 159 diffusion tube monitoring locations in the borough (62%) exceeded the legal limit. From 2018 to 2024, NO2 concentrations have reduced by an average 43% at our automatic monitoring sites and 45% across our diffusion tube monitoring sites (where data is available). 2024 was also the first year in which there has not been a recorded exceedance of the short-term (24-hour) PM10 air quality objective in Camden.
Our transport strategy, sustainable travel policies and infrastructure improvements have supported this significant reduction in roadside air pollution throughout the borough.
As well as operating Camden’s extensive monitoring network, our Air Quality team has had a busy year, with the commencement of several projects, including The Year of Clean Air for Camden Schools, Cleaner Filming for Camden, and indoor air quality sensor loans for residents. As well as these, we have either supported or extended existing projects, including the London Wood Burning Project, Idling Action London, and Healthy Waterways London, all with funding support from the Mayor of London. These projects all serve the same ultimate purpose, to ensure Camden is a borough in which no person experiences poor health as a result of the air they breathe.
On Camden’s journey to WHO levels, the council can report that:
- The number of electric vehicles within our fleet has risen five-fold since 2018, with 14% of vehicles now fully electric.
- For the second year in a row, all of our automatic monitoring sites have achieved the 2030 London Mayoral Objective of 10 µg/m3 as an annual average limit for fine particulate matter (PM2.5). Despite this, all four monitoring sites are in exceedance of our WHO-aligned PM2.5 target of 5 μg/m3. The World Health Organization considers there to be no safe threshold of exposure to PM2.5; we will strive to go beyond the Mayoral Objective and further improve air quality throughout the borough to better protect the health of all who live, work and study in the borough.
Our automatic air quality monitoring data can be found on the London Borough of Camden - Air Quality monitoring service and our diffusion tube data can be viewed on our Open Data platform.
