Delhi’s Car Ban Experiment Didn’t Improve Air Quality That Much, But it Should Still Be Permanent

before this year Delhi ’s atmosphere pollution was so bad that the government temporarilybanned half its car from street . The policymaker who came up with the idea says the ban should be 365 days a class — but not because it improved air quality all that much .

The “ odd / even ” scheme allow drivers to use their car every other Clarence Shepard Day Jr. depending on the last digit of their license plate identification number . The forbiddance only lasted two weeks , and there was a slight improvement in atmosphere quality — particulate matter issue dropped about 18 percent , according to an independent cogitation . But the problem with prohibition like this is that as soon as the cars return , so does the smog . Delhi adds1,400 more cars to its streetsevery twenty-four hour period .

Although the flyspeck improvement in air quality melioration is a nice understanding to keep the ban going , it ’s not what ’s motivating Anumita Roychowdhury , director of the city ’s Centre for Science and Environment , to make it lasting . She told CNNthat even if the ban would n’t affect befoulment level right away , force half the population to get out of their cars every day would guarantee that the government would ready the public transportation system problem — includingaccommodating lower - income and female riders — and address outdated revenue enhancement incentive :

“ You are in reality make it cheaper for me to use my car than to take public transportation , ” Roychowdhury said . Bus ridership has put down from 60 % in 2000 to 41 % today . “ The satire here today in Delhi is that automobile are carrying about 14 % of the travel demand , but 80 % of transport investment in the city is tied to roads that facilitate car drift , not public transfer . ”

That dissymmetry of investment is the trouble in most cities , but in Delhi it is literally killing citizenry . The air quality is so spoilt in India that the country was cited in arecent studyafter 1.4 million resident died prematurely from lung and cardiovascular disease in 2013 . And it ’s causingpermanent hurt in tike .

There are bigger reform that take to be made , too — ember - fired plants should be taken offline , and the far-flung combustion of forest and meth needs to be baffle — but I think I agree with Roychowdhury that extending the car forbidding would force a radical reshifting of everyday behavior and the city would have no selection but to change quickly to support it .
