It's only 15%.

At this time every year, the air quality (AQI) in the national capital Delhi becomes extremely polluted, with certain areas reaching dangerous levels. aqi.in. Analysis by the Centre for Science and Environment found that motor vehicles contributed half or more to pollution. "This is followed by household pollution that has ranged between 12.5 and 13.5 percent, industry (9.9-13.7 percent), construction (6.7-7.9 percent), waste burning and road dust (each varied between 4.6-4.9 percent and 3.6-4.1 percent, respectively." In 2015, New York Times journalist Gardiner Harris left Delhi after a 3-year stint because his eight-year-old son Brad's lung capacity had fallen by 50% due to the poisonous Delhi air. BuzzFeed. He wrote a stinking article on stinking Delhi. To which Padma Rao Sundarji's American friend commented, "There goes another bitch-slapper. Good riddance." HT. A study by Ummed Singh Saharan et al on "Drivers of air pollution variability during second wave of Covid-19 in Delhi, India" concluded that "air pollution control in Delhi should target the burning of fossil fuels, solid biofuels in households, solid waste dumping sites, and agriculture fields not only at the local level in Delhi but also in neighboring states." "PM2.5 levels have increased from 63 micrograms per cubic meter in 2012 to 141 in 2019. This dipped to 115 in 2020 due to Covid lockdowns," wrote Chandra Bhushan. Still dangerously high despite almost complete halt in all activities. Because, "In 2019, the country burnt 1,830 million tonnes (MT) of fossil fuels and biomass to meet its energy needs. In addition, about 100 MT of garbage were burnt in the open. In totality, we burnt at least 1,950 MT of materials of which 85% was coal and biomass, and petroleum products were less than 15%." "The high price of oil has led to renewed calls for the use of electric vehicles (EVs) to lower human dependence on fossil fuels which pollute the environment," wrote Vivek Kaul. EVs need electricity to charge their batteries. "In the Indian case, in 2010-11, 65% of our power generation capacity depended on fossil fuels. In 2020-21, this was down to 61.4%." "In absolute terms, coal-based power capacity jumped from 93,918 magawatts to 202,675 megawatts." Vaclav Smil wrote that a typical EV battery weighs 450 kg, consisting of "about 11 kg of lithium, nearly 14 kg of cobalt, 27 kg of nickel, more than 40 kg of copper, and 50 kg of graphite - as well as about 181 kg of steel, aluminium, and plastics." Extraction of all that will need vast amounts of fossil fuels. "Compared with traditional internal combustion engine (ICE) vehicles, greenhouse gases released while making battery-electric cars account for a higher portion of life-cycle emissions," wrote Anajani Trivedi. "The metals used both by ICE vehicles and battery-electric ones make up 53% and 47% of manufacturing carbon footprint, according to Greenpeace report." Thus, despite there being no evidence of benefit, all petrol-drive cars have to be scrapped at 15 years of age in Delhi. TOI. Because they will not stop stubble burning, biomass burning or construction. These affect the vote-bank.
