Get in touch with an air quality expert
Cities globally grapple with unparalleled challenges concerning air quality and climate change. As part of the C40 Clean Air Cities Declaration, mayors have dedicated themselves to delivering clean air in their urban landscapes. This commitment, supported by the Clean Air Fund, is aimed at fostering healthier, more sustainable environments for over 140 million residents.
Clarity offers advanced air quality monitoring solutions specifically tailored to the needs of C40 cities looking to deploy climate-resilient infrastructure at the city-wide scale.
Here's how Clarity can be your partner in creating a cleaner and healthier future:

Addressing urban air quality challenges
“The air quality data provided by the Dashboard will serve as a foundation for designing policies, allocating budgets, and developing programs to address urban public health challenges.”
"Clarity’s innovative technology has significantly improved our understanding of urban air pollution and its impact on public health and the environment. The system’s accuracy, reliability, and user-friendly interface have proven to be extremely effective tools for both decision-makers and the public. It provides real‑time, accessible data that enables informed policy development and empowers citizens with the knowledge to take action. This initiative has been highly appreciated by local authorities, environmental specialists, and the general public.”
"We have installed sensor monitors at 3 locations to detect sources of air pollution. What does this mean? This means that every citizen of the municipality of Strumica is an inspector from today and will be able to monitor concentrations of PM2.5 particles from the sensor monitors, and this application will also be implemented in the Inspection Services of the municipality of Strumica, where air pollution will be monitored around the clock, and they will be able to react quickly to sanction negligent polluters. After electrified public transport and bicycle paths, with this innovative project, we prove that we are seriously investing in reducing air pollution in Strumica."
“With Clarity's hyperlocal network, we can begin to provide a more complete picture of how air pollution is occurring in a given micro region, and what preventive actions we need to take to minimize exposure. We can also measure the effectiveness of each activity taken by measuring concentrations BEFORE and AFTER that activity. This encourages us to think about policies that we want to change. It raises citizen awareness and creates a narrative that influences positive change. We need to know what the air is like NOW AND IMMEDIATELY, at each MICRO location, to react IMMEDIATELY, and to sanction those who are disrupting our health, the future of our youngest, and the future of our country. Every citizen of the municipality of Strumica has a strong ally in such innovative technology."
"The data provided by the sensors helped to speed up the city’s decision-making. Today, the sensor readings have had a direct impact on public opinion. This year, we launched public ecological transport and eco-taxi, and we are launching a new system of dedicated public transport lanes that will directly affect the transition to eco-friendly modes of transportation.”
Addressing urban air quality challenges
Cities today grapple with significant challenges posed by air quality and its impact on health, economies, and vulnerable communities. Clarity’s air quality measurement solutions provide the data required to address these challenges.
Public health costs of air pollution
Poor air quality leads to premature deaths, increased disease burden, and negative economic consequences.
Climate-vulnerable communities
Disadvantaged communities within cities are disproportionately affected by the health risks of dirty air & climate change.
Lack of air quality data
Scarce air quality data hampers effective policymaking and obstructs progress towards cleaner air.
Need for air quality targets
Setting and achieving ambitious air quality targets aligned with global standards remains a challenge for cities lacking baseline air pollution data.
Tackling air pollution and the climate crisis go hand-in-hand. Both need swift, unprecedented and collective action to removethe pollution that is harming our health and warming our planet.

Frequently Asked Questions
What is the goal of the C40 Breathe Cities initiative?
The C40 Breathe Cities initiative aims to accelerate clean air action in cities around the world by providing funding, technology, and technical support to measure air pollution and implement data-driven policy solutions. The program focuses on reducing exposure to air pollution and advancing environmental justice in communities most impacted by poor air quality.
How is Clarity supporting air quality efforts in global cities through this program?
Clarity is a key technology partner in a variety of Breathe Cities projects, providing Sensing-as-a-Service solutions that include solar-powered air quality sensors, cloud-based data platforms, and expert project support. Our technology is currently deployed in Breathe Cities like London, Accra, and Jakarta, helping local governments and stakeholders gain real-time insights to support air quality interventions. Learn more in our post on Breathe Accra.
What kinds of data are being collected in Breathe Cities projects?
Cities participating in the program collect high-resolution data on pollutants such as PM₂.₅ and NO₂, using Clarity’s Node-S sensors. Some cities also integrate Multi-Gas Modules or Black Carbon Modules to capture additional emissions. This granular data helps cities understand hyperlocal pollution patterns and identify sources of pollution in real time.
How do cities use this data to drive policy and improve air quality?
City governments use the air quality data from Breathe Cities deployments to shape evidence-based policies, such as emission zones, traffic management, and health advisories. In Jakarta, for example, the data is being used to support low-emission transport planning and public health outreach. By visualizing data with tools like Clarity OpenMap, cities can also engage communities and increase accountability for clean air efforts.
Can other cities join or replicate the Breathe Cities model?
Yes — while the initial cohort of Breathe Cities was selected by C40, the model is replicable by any city or organization seeking to address air pollution with data-driven action. Clarity provides scalable sensor networks, advisory services, and open-data platforms that make it easier for other cities to launch similar initiatives.
