India’s obsession with diesel and the promotion for years of the relatively unclean fuel in the form of heavy subsidy is reflected in the pollution levels in the Delhi air. Among drastic reforms being undertaken is the re-routing of heavy vehicles crossing the capital and the temporary ban on sales of upmarket high-power SUVs. While the move against SUVs may serve only populist ideals, the restrictions on trucks, the additional cess on their plying and CNG for all taxis will all do their bit for the Delhi air. There can be no second opinion that far more must be done to clean Delhi’s atmosphere, said to be the world’s worst now.
Automobiles are not the only villains but diesel fuel is a major pollutant whose use has grown 40 per cent in the last four years, including in shopping malls and telecommunication towers. Medical research has concluded that diesel fumes cause lung cancer. The burning of chaff and crop residue in agricultural fields in neighbouring states and construction dust and debris are other major pollutants. The critical view of diesel is only a starting point of reform. It is as well that the highest judiciary is seized of the urgency of the reform process and has lent moral support in agreeing to car pooling to serve the odd-and-even number plates rule as well as its legal prowess in strong directions against heavy vehicles and the construction industry. Corrective measures must also include the active promotion of inner city connectivity of the Metro, buses and other public transportation. Delhi is the classic test case of India’s will to act for the environment.
