NEW DELHI 29/NOV/2014: Centre for Science and Environment has recommended that the government use taxation and pricing tools to bring down the number of diesel vehicles in Delhi and other cities. CSE has demanded tax measures to create a \"clean fuel fund\" which can financially support the government\'s effort to introduce clean diesel through Euro V norms soon. \"Though diesel price deregulation and the consequent lowering of the price difference between petrol and diesel has slowed the rate of increase in the diesel car segment, low tax diesel continues to lure consumers,\" a CSE statement said on Friday.
Central Pollution Control Board (CPCB)\'s air quality data shows pollutants related to diesel emissions like particulate matter (PM 10 and PM 2.5) and oxides of nitrogen have been increasing. CPCB\'s 2009 review of air pollution had found that 102 cities monitored exceeded the standard for PM10, and in 2012 that increased to 137. \"Cheap diesel creates incentive for more driving and for bigger cars. This results in more fuel use and more toxic pollution per km. WHO has branded diesel particulates as Class I carcinogens for their strong link with lung cancer,\" the statement said.
Experts at the meeting like Manfred Breithaupt, senior transport advisor at GIZ, a German body that advises governments on sustainable development, suggested financial tools such as the CO2-based car taxation used in France, very high car registration fee used in Shanghai and Singapore\'s vehicle quota system under which car owners need to pay a steep fee for a certificate of entitlement (COE). Delhi School of Economics associate professor Shreekant Gupta also suggested that electronic road pricing in Singapore which automatically takes a congestion charge, and the London congestion tax model which has managed to discourage personal vehicle usage in many parts of the city can be followed.
