Birmingham City Council


Air quality is a significant health concern for Birmingham. Birmingham City Council wanted to raise awareness of the causes of air pollution and the steps that can be taken to reduce emissions and exposure. 

This particular project was aimed towards children and parents via the installation of indicative air quality sensors onto the exterior façades of a number of schools (mix of primary and secondary). One sensor will be deployed per school per Council Ward. The Council wanted sensors to  be deployed along with a static signage board with information and links to online resources.

The Council wanted to provide 140 schools with the sensors for a period of at least 1 year.

Expected results

Birmingham City Council plan to use the project as the first step towards improving air quality in Birmingham providing hyper-local, real time data that will enable them and residents to make informed decisions to lower pollution levels across the city. 

Councillor Waseem Zaffar MBE, Cabinet Member for Transport and Environment at Birmingham City Council has said: “There is clear evidence that air pollution can have long and short-term health implications. Our ambition is to create an environment where people can live and work to their full potential without the threat of this entirely preventable pollution.

“It is a promising next step for us today to be able to launch the Air Pollution Sensors project with Airly as this will help us create further awareness across our communities of how the air pollution situation is progressing. Now it is time for us all to think about changes we can make to create a difference, as individuals and as organisations.”



The project is a collaboration between Airly, Birmingham City Council and Evotech who will be installing all the sensors.

The course of the project

The project is expected to last between March 2022 for a year, with sensors at 70 schools to begin with, with a further 70 schools being provided with sensors later on in the year.

Birmingham City already had a selection of schools chosen beforehand for this project but Airly has helped create a dedicated landing page for the project where we have seen further interest from schools in the City that are keen to join the project, which highlights the benefits of raising awareness about air quality within Birmingham City. 

Evotech will be installing all the sensors for the project. Compelled by the worsening levels of air pollution in the UK, Evotech Air Quality was launched in early 2020 to help customers create safer working environments by transforming their indoor and outdoor air quality. As part of the Evotech Technical Services Group, a national HVAC engineering company founded in 2003, they are a growing team of engineers, technicians and data scientists passionate about the air we breathe. They not only provide air quality monitoring solutions but specialise in helping our clients improve their indoor environments through the installation / upgrading of mechanical ventilation systems and the latest in filtration and air sterilisation technology.

Services that Airly is providing

Airly will provide all schools involved in the project with air quality sensors for the contract period. Along with the sensors, Airly is providing:

Signage boards to raise awareness of the sensors and to provide more information on air quality and Birmingham City’s Clean Air Strategy

Data relating to air quality from the sensors provided on a dashboard that gives the Council full control and oversight on each sensor across the city and an online mapp and app that residents can use to view air quality in their area at all times

In addition to those, we have offered our assistance to help the Council put together educational resources for the schools to further help raise awareness around pollution and the steps that can be taken to improve air quality

Background: Why Birmingham decided to invest in air quality

Birmingham City is the second largest city in the UK with 4.3 million inhabitants within the metropolitan area. Poor air quality is the greatest environmental risk to public health in the UK. Between 2010 and 2019, estimated emissions of nitrogen oxides in the UK fell by 32%, estimated emissions of PM10 particulate matter fell by 10% and estimated emissions of PM2.5 particulate matter have fallen by 11% (Defra, 2021). 

According to the data released in the lead-up to World Health Day in 2022, almost the entire global population (99%) breathes air that exceeds new WHO air quality limits, and threatens their health.
