The United States plans to expand air quality monitoring at some U.S. embassies and consulates to help increase awareness on the dangers of pollution.

The initiative announced Wednesday by the State Department and the Environmental Protection Agency builds on a monitoring service begun five years ago at the U.S. Embassy in Beijing.

Secretary of State John Kerry says the service will expand to India, Vietnam, Mongolia and elsewhere.

He says the monitoring will provide information to U.S. foreign service officers, members of the military and Americans abroad, and help build international cooperation on curbing .

The information will be provided on an EPA website, AirNow—www.airnow.gov—that already has air monitors at nearly 4,000 locations in the United States.
