We need fresh solutions in the battle for clean air

Air pollution remains one of the world's biggest environmental challenges. Despite progress with the introduction of ambient air quality standards in countries around the world, many regions and communities still struggle with dangerous levels of pollution.

We believe it's time for Air Quality Management 2.0 — a new model focused on achieving measurable improvements in public health and air quality through high-resolution air pollution measurement and cross-sectoral collaboration.

Building partnerships globally with organizations like:

Better air quality management programs start with modern technology

Our air quality monitoring technology can play a key role in Air Quality Management 2.0 — providing air quality data that serves as the foundation for coordinating four key stakeholder groups critical to successful air quality management: Communities, Regulators, Technologies and Analysts.

Together, these components form a closed-loop cycle where air quality monitoring provides a foundation of evidence to guide policy and instigate action from regulators while providing more transparency and localized benefits to our communities. The resulting emission reductions and health benefits feedback to justify sustained monitoring and analysis.

Air Quality Management 2.0

Air Quality

It’s essential that community voices are part of the conversation when it comes to air quality improvement initiatives and policy change, as they often bear the brunt of air pollution’s negative impacts on public health.


Regulators play an essential role in transforming the insights from air quality monitoring data into policy initiatives that make an impact on air pollution reductions and public health outcomes.


Play a pivotal role in spotting trends, modeling pollution, and guiding interventions for improved air quality and public well-being through data-driven insights.


Air quality data is the foundation on which cross-sectoral partnerships are built. Technology like low-cost air quality sensors can help bridge the gap that exists in data collected by often sparse regulatory-grade monitors.

Breathe London: Building a 400+ sensor network for a global city

Our work with the pioneering Breathe London program demonstrates how Air Quality Management 2.0 can succeed. This cross-sector initiative harnessed our air quality sensor networks along with advanced data analysis to identify pollution hotspots. This enabled targeted policies to reduce Londoners' exposure and improve public health outcomes. Clarity aims to replicate this model in more cities to create sustainable, effective air quality programs.

By advancing Air Quality Management 2.0, we strive to provide every community with clean air. Let's work together towards a future where no one has to breathe dangerous pollution.

Royal Automobile Club, Western Australia

The RAC Air Health Monitor is the largest air quality sensor network in Australia, launched by the Royal Automobile Club (RAC) of Western Australia. The network consists of over 200 sensors across the Perth metropolitan area measuring particulate matter (PM2.5 and PM10) and nitrogen dioxide (NO2). Transport emissions are a major source of these pollutants.

The sensors provide real-time, hyperlocal air quality data at a high resolution of 200m x 200m. An interactive model combines sensor data with traffic information and vehicle emissions data to map pollution levels.

Almaty Bishkek Economic Corridor

Prior to 2022, Almaty and Bishkek had extremely limited air quality data, with just a single regulatory monitoring station in each city. ABEC deployed dozens of Clarity Node-S devices throughout both cities to provide previously unavailable hyperlocal air pollution data.

The sensor networks helped identify seasonal spikes in pollution during winter months from vehicles and residential heating. Analysis by city agencies guided the development of cleaner heating and transportation policies.
