India's capital, laboring¹ under the label of being the world's most polluted city, is trying something new to help clean up its air. 

 

深受“世界上污染最严重的城市”这一头衔困扰的印度首都新德里，最近出台新举措净化空气质量。 

 

A smartphone application that allows residents to report the presence of construction dust or the burning of leaves and garbage in New Delhi's public parks to authorities was launched Friday. 

 

The "Hawa Badlo," or "Change the Air," app has two versions. One allows people to take pictures of likely pollutants². The other allows authorities to investigate and act on valid³ complaints. 

 

Over the last few years, New Delhi has struggled with ways to handle the pollution, which becomes especially obvious during the colder winter months as the city's air turns to a gray haze⁴.

 

The newest measure, the phone app, was launched by the Environmental Pollution (Prevention and Control) Authority, a monitoring group set up on the order of India's Supreme⁵ Court in April.
