The City Clean Air Hub

A one-stop resource to help city leaders tackle local air pollution and chart a path to cleaner air and healthier communities.

About the Hub

Your city’s residents deserve to breathe cleaner air.

We’re here to help you make that a reality.

Air pollution is a silent and often invisible killer — the second leading risk factor for early death worldwide. It also shares many of the same root causes with — and is being worsened by — climate change.

The good news is solutions exist. The City Clean Air Hub is built to help cities chart a path to cleaner air and to connect them with the data tools, resources and policy insights that they need to get there.

What can the City Clean Air Hub help your city do?

How air pollution affects health in your city

City residents feel air pollution’s effects every day through rising asthma cases, emergency room visits, cancer diagnoses and more. Beyond the health costs, air pollution carries enormous economic costs — more than $1 trillion every year in the United States. Focusing solutions on groups that are most affected is key to maximizing health benefits and correcting the legacy of unfair treatment.
