The debate over air pollution due to vehicular emissions is not new.
Despite several announcements of stricter emission norms as well as the apex
court's criticism, the government has been lax in their implementation. Last
year, the state government had announced that pollution under control (PUC)
certificates would be made mandatory for refuelling at stations. It was
supposed to be launched this year but the plan remains on paper. It's not the
first time that the courts have tried to tackle rising air pollution in the
city. In 2000, the Supreme Court had ordered mandatory pollution checks of all
vehicles. It had also asked that an automated inspection and maintenance system
be set up at the earliest.
