EPA and Shanghai EPB developed AirNow International, building on Shanghai’s existing air quality monitoring network and capability in analyzing air quality data. EPA provided technical assistance to Shanghai, a city of more than 17 million people, to begin reporting the data to the public as it becomes available.

AirNow International is one of the many ways EPA is working with the Chinese government to address key environmental issues in both countries. EPA and China’s air quality collaboration includes advanced air quality modeling to understand air pollution sources and reducing emissions from vehicles, power plants and other industries.

The two countries also are working together to address issues related to climate change, water, toxics, solid and hazardous wastes, and environmental governance.

EPA’s AirNow program has expanded in its 11 years. The program provides air quality forecasts and data reporting for nearly 400 US cities.

Gina McCarthy, assistant administrator of office of air and radiation at EPA, said: ”AirNow has been an extraordinary tool for helping the public understand air pollution in the US. We’re pleased to be working with Shanghai to use this technology to make real-time air quality data available in China.”
