Airly Map
A sensor on a construction site in Birmingham. Another on a rooftop in Athens. A third near Belgrade, in an area where industrial activity and residential heating push pollution well above what reference stations typically capture.
Three cities, three very different contexts, but the underlying problem is identical. Need for reliable data about the air people actually breathe.
Air quality is a universal problem, but it plays out locally. Pollution sources and regulations differ as well. This is why Airly has built its global presence through a network of local partners who understand their own markets, their own regulatory environments, and the specific needs of the people they work with. Today, Airly sensors are active in more than 50 countries across four continents. Read more about our global air quality monitoring network.
The partners
In the UK, AcSoft, a leading supplier of noise, vibration, and air quality instrumentation, began working with Airly on a construction site pilot in Birmingham. Until now, AcSoft has since deployed over 200 Airly sensors across UK construction sites.
In Greece, Imoconsult has embedded Airly’s technology into municipalities across the country, often integrating sensors into smart streetlighting infrastructure.
Dirigent Acoustics covers countries across the Western Balkans, including Serbia, Bosnia and Herzegovina, and North Macedonia. This is a region where air pollution ranks among the most severe in Europe, driven by coal-based heating, ageing industry, and limited monitoring infrastructure.
In Romania, BEIA Consult connects Airly’s technology to research institutions, EU-funded projects, and ESG compliance monitoring.
Onyx Enerji operates in Turkey, a market with significant industrial air quality challenges and growing demand for credible environmental data from manufacturing zones, refineries, and urban authorities.
In India, Welan Technologies navigates one of the world’s most complex procurement landscapes, working through smart city integrators to reach municipalities and regional pollution control boards.
Fybra brings Airly into Italy through municipal projects and European research frameworks.
In Belgium and Luxembourg, ISI sa-nv focuses on municipalities, compliance monitoring, and ESG.

Why does it matter? Beyond the milestone
Fifty countries mean fifty different regulatory frameworks, fifty different political contexts in which the argument for monitoring has to be won, and fifty different sets of communities whose health depends on whether it is.
What these contexts share is the same underlying need: data reliable enough to act on.
The WHO’s 2021 air quality guidelines set a benchmark that most countries have not yet met.
In Europe, the pressure is now also regulatory: the revised Ambient Air Quality Directive (AAQD 2024), adopted by EU member states in 2024, significantly tightens limits for PM2.5 and NO2 and comes into force in 2030.
As regulatory pressure intensifies, the demand for a dense, trustworthy global air quality monitoring network will continue to grow.
The 50-country network is a milestone. It is also, more importantly, a foundation.
