OPINION: What Clean Air in Nairobi Should Really Feel Like

“By 2029, success will mean that people in Nairobi can genuinely say the air feels better. It will not just be technical progress. It will be a lived experience.”

That is how Maurice Kavai, Deputy Director for Climate Change and Air Quality Monitoring at Nairobi City County, defines success.

Not dashboards. Not reports. Not workshops.

Just this simple feeling: the air feels better.

For anyone who lives in Nairobi, that statement lands close to home. Parents walking children to school through traffic fumes. Street vendors work all day beside busy roads.

Commuters stuck in jams, breathing exhaust they cannot see but feel in their chests. For many residents, air pollution is not an abstract environmental issue. It is a daily reality.

Through initiatives like Breathe Cities Nairobi, the city has begun treating air quality data not as technical information for experts alone but as a public good.

This work supports expanded air quality monitoring and evidence-based planning, helping make pollution visible and understandable to both decision-makers and residents. With the launch of the Air Quality Action Plan for 2025 to 2029 and the installation of monitors across neighbourhoods, Nairobi now has a system that shows, in real time, what people are breathing.

This is progress. But it is not the end of the story.

As Kavai puts it, clean air will not come from plans alone. It will come from what happens next.

The difference between data and daily life

Air quality monitors can tell us how polluted the air is. They can show levels of harmful particles such as PM2.5 and PM10, which are linked to asthma, heart disease, and early death. But numbers on a screen do not clean the air by themselves.

The real question is what the city does with this information.

Data must lead to action. Action must lead to enforcement. Enforcement must lead to healthier streets.

If that chain breaks at any point, nothing changes.

County officials working on the ground see this clearly. One borough official notes that many residents still do not understand how air pollution affects their health or what actions worsen it. Open waste burning, construction-site dust, traffic congestion, and poorly regulated industries continue to pollute the air, especially in informal settlements.

At the same time, enforcement teams often lack the training, equipment, or public support needed to act effectively. When people do not trust or understand the data, regulation feels like punishment rather than protection.

This is why communication matters as much as technology.

When air quality data is clearly explained and openly shared, it can reduce conflict. It helps communities understand why certain rules exist and how behavior change can protect their families. It also helps the government enforce standards fairly and consistently.

Pollution does not come from one place. Nairobi’s air pollution does not have a single cause. It comes from vehicles, industries, construction sites, waste burning, and household energy use. No single department can solve it alone.

The transition of the Nairobi Air Quality Working Group to joint leadership by the County Government and the National Environment Management Authority is an important step. It signals that air quality is no longer a side issue. It is a governance issue.

But coordination is not automatic. It must be built, maintained, and funded.

Experts working with the city point out that many enforcement gaps are not about lack of laws, but lack of understanding. If officers cannot interpret air quality data, they cannot use it confidently. If pollution is invisible, it is often treated as harmless.

This is changing.

Nairobi’s clean air journey is now entering a different phase. It is no longer about launching new plans. It is about learning how to use the tools already in place.

Clean air is not just about the environment. It is about health, productivity, and dignity. Fewer hospital visits. Children who can play without wheezing. Workers who are not constantly sick. Streets that feel safer and healthier.

That is why the city’s ambition matters.

By 2029, success should not be measured by the number of policies written. It should be measured by how Nairobians feel when they step outside.

If the air feels better, the data will show it.

And if the data shows it, then Nairobi will have proved that clean air is not just a promise, but a lived reality.
