MUMBAI: CNN correspondents will report from across Asia on the most polluted cities in a half-hour focus on the continent’s environmental crises and the threats they pose to the rest of the world in Ill Wind: Asia’s Pollution Crisis. The special airs on 4 June at 4 30 pm and 11 30 pm.

Anchored by Anjali Rao from Hong Kong, Stan Grant, Jill Dougherty, Ram Ramgopal, Atika Shubert and Kristie Lu Stout analyse both the causes and effects of pollution in reports from India, China, Hong Kong, Japan and the US.

Ramgopal reports from New Delhi which, despite having won praise for converting its public transport fleet to less polluting natural gas, is now under assault from a two wheeled traffic boom.

The journey continues towards the west coast of the United States where Kristie Lu Stout reveals how pollutants from Asia are beginning to be detected in the air and water.

In a sign of how things may improve, Tokyo bureau chief Atika Shubert reports from Kawasaki, a city that was once a “pollution nightmare” that has transformed itself into an “eco-town”. The city’s environmental model aims to strike a rare balance between the needs of development and growth while greatly reducing pollution.
