Subsequent to the NGT order, only one serious effort has been made to check random vehicles for age at the Burari depot when transport minister Gopal Rai was present. We should be seeing more such checks. Second, control dust from construction sites. Again the NGT had ordered the authorities to check Noida Extension and Gurgaon after the `Death by Breath’ series by The Indian Express (April) had pointed out violations of construction safety guidelines to minimise air pollution. These checks need to increase in Delhi and NCR — not just in real estate but also at public construction sites. Thirdly, continue the discussions that the union environment minister had started with NCR authorities on treating pollution as a cumulative NCR problem with regard to guidelines for quality of diesel, engines, air quality monitoring and construction dust, etc. Treating air pollution in Delhi as an isolated problem will not help, as experts have pointed out time and again. There have been two such meetings where environment ministers from different states participated, but the practice has not gone forward.
