Delhi Chief Minister Arvind Kejriwal was on Friday named by Fortune magazine as one of the World's 50 Greatest Leaders -- for his innovative odd-even traffic scheme to battle pollution.The Aam Aadmi Party (AAP) leader took the 42nd place in the list.Responding to congratulatory messages, Kejriwal said: "They (have) included my name for odd-even, credit for which goes to people of Delhi who made it successful." Fortune magazine said: "When Kejriwal unveiled a blueprint to tackle the smog in New Delhi - called the world’s most polluted city by the WHO - many were skeptical. A key component: an 'odd-even' pilot project in which vehicles were allowed on the roads only on alternate days. The uplifting result of the pilot this January: Roads were less clogged, hourly particulate air pollution concentrations dropped by 13 percent and citizens could breathe deep."
