There was not even a single voluntary response to the Delhi government's ambitious scheme of persuading operators of old diesel-run light goods vehicles (LGVs) to switch over to new CNG-run vehicles by offering them a whopping Rs 80,000 (12.5 per cent) tax incentive per vehicle. Out of a total of 38,500 diesel-run LGVs registered, over 5,000 are between 14 and 15 years old The scheme which was announced in February this year to persuade owners of 14 to 15 year old diesel-run light goods vehicles to switch over to more eco-friendly CNG-run ones, closed on April 30. According to the transport department of the Delhi government, out of a total of 38,500 diesel-run LGVs registered, over 5,000 were between 14 and 15 years old and it was this group which was being targeted by the Delhi government in order to bring down the pollution levels in the National Capital Territory of Delhi. However, the officials of the transport department were surprised by the fact that not even a single operator turned up to register under the scheme and take advantage of the tax exemption offered. According to the Indian Foundation of Transport Research and Training (IFTRT), which closely monitors the transport scene in the National Capital Territory of Delhi, this was because of the fact that it was more profitable for the owners of 14 to 15-year-old diesel-run LGVs to continue with the old ones rather than invest in new CNG-operated vehicles despite the offer of hefty VAT exemption. It was simply a matter of profit. The Delhi government would have to take some drastic measures if it wants to bring about a tangible change in the air pollution levels. The IFTRT also revealed that it was ironical that the joint Delhi government joint venture Indraprastha Gas Limited (IGL) engaged in the distribution of clean auto fuel
