Air quality reports
Improving air quality on and around our network
We are working with the government to help improve air quality in the England by reducing Nitrogen Dioxide (NO2) levels and supporting the delivery of the UK NO2 Plan.
The government’s Pollution Climate Mapping (PCM) model identifies roads that might exceed the legal limits for air pollution at 40µg/m³.
Some of the roads the PCM has identified are part of our strategic road network (SRN) in England.
We've created a map that shows:
- these locations on our Strategic Road Network
- our latest understanding of the ambient concentrations near these links compared to the annual mean NO2 limit value
The map also shows:
- the locations of automatic air quality monitors on our road network
- the annual mean NO2 concentrations recorded by these monitors
The government has asked us to:
- look closely at the areas where air pollution might be too high
- put in measures to reduce pollution as quickly as possible in places where it does go over the legal limits
Air Quality – Annual Evaluation Reports
In response, we published a series of detailed assessment reports, which describe the work we have to do and report on the air quality alongside our network.
For areas where pollution is above the legal limit, we review air quality every year. This helps us see if the NO2 levels have reduced and if the steps we’ve taken are making a difference.
Our Air Quality Annual Evaluation Report for 2023, published in our Annual Report and Accounts 2024, shows an improving picture of air quality alongside our network.
Initially, we reviewed 128 sections of our network where air quality was identified as at risk of exceeding legal limits. Over the last five years, our work to improve air quality means that over 90 of those sections are now below the legal limit.
In 2022, we reduced 8 more sections of our network to below the legal NO2 limit and our latest report for 2023 shows we have reduced another 10 to below the legal limit.

National Highways Air Quality Monitoring Network (NHAQMN) reports
These reports give summary results from our air quality monitoring network since its creation in 2016.
We operate a network of automatic monitoring stations across the Strategic Road Network.
Data from these monitors helps us understand Nitrogen Dioxide and, more recently, particulate matter around our network.
Particulate matter (PM) means microscopic solid or liquid particles suspended in the air. These particles are categorised by size - for example, PM2.5 means particles with a diameter of less than 2.5 micrometres (µm). PM caused by road traffic includes exhaust emissions as well as tyre and brake wear.
This data informs our programme of activity to improve air quality.
If you need help interpreting this information, or more detailed data from a specific monitor, please contact us at Airquality@highwaysengland.co.uk.
Supporting technical information
Here are the technical reports covering our assessment of the PCM links on our network.
As we progress through each phase we update baseline maps and audit reports to include our findings from earlier phases.

The Phase 3 (Commission No. 1) report builds on the work completed to date. The report presents updated air quality modelling, new air quality monitoring data and comes to a conclusion for each section of the Strategic Road Network (SRN) whether they exceed the annual mean nitrogen dioxide (NO2) limit value or not and the date compliance would be achieved. For those sections which have been identified as above the annual mean NO2 limit value a range of measures have been considered and where they can be delivered the report sets out the anticipated reduction in NO2 concentrations.
Commission 1 Phase 3 Air Quality Report
Following completion of the Phase 3 assessment (Commission No. 1), the Joint Air Quality Unit (JAQU) asked National Highways to undertake a sensitivity analysis for 37 sections of the Strategic Road Network (SRN) using a different air quality model and the latest vehicle emission factors. The sections of road identified by JAQU had previously been modelled as just below the annual mean nitrogen dioxide (NO2) limit value of 40ug/m3. The purpose of the sensitivity test was to check if the previous modelled outcomes remain below the limit value and JAQU could be confident in approving all the findings in the Phase 3 assessment.
The report showed the updated modelling had very similar outcomes to the air quality assessment previously shared in the original Phase 3 assessment (Commission No. 1) with JAQU. This meant there was no change to the original findings set out in the repor

PCM Link Evaluation Strategy
Following the agreement with the Joint Air Quality Unit (JAQU), a number of links have been identified as above the permissible levels.
We have developed an evaluation strategy to:
- understand and report when each link is compliant
- determine whether any mitigation is delivering the improvements
- confirm when any mitigation can be removed whilst ensuring the section of the SRN remains compliant
Evaluation approach
Air quality monitoring to be deployed for all links confirmed as non-compliant and assessed within 10% of the limit value, i.e. (36-40µg/m³).
Monitoring to be deployed to at least one site as a minimum, but ideally three, alongside the SRN representative of qualifying feature(s).
Monitoring will continue for at least two years after the respective section of the SRN is modelled to come into compliance.
Monitored concentrations will be evaluated at 6 month intervals, (allowing 2 months for tube analysis by the labs):
- mid-year review - end Aug year – covering first 6 months
- annual review and report - end Feb year – calendar year annual average
Removing mitigation will be recommended when concentrations are reported below 36µg/m³.
