Currently in India the Petrol and Diesel being used in vehicles is the BS-IV variety. The BS-IV fuel contains a lot of chemicals. When used it produces a lot of pollution and harms the environment. Last year on 24th October 2019, the Supreme Court ruled that sale of BS-IV fuels will be stopped with effect from April 1, 2020. Instead, BS-VI fuel will be sold from 1st April. The BS-VI fuel when used in vehicles in emits extremely less harmful gases and doesn’t harm the environment. Now people will have to pay slightly more for the BS-VI fuel. Indian Oil Corporation (IOC) is the largest oil supplier in India. On 28th February, it said they are all ready to supply the BS-VI fuels from 1st April. The IOC has spent over ₹17,000 crore to upgrade its BS-IV refineries to produce BS-VI fuel. Their Chairman Sanjiv Singh did not announce the new prices but he said that, there will be slight increase in prices but price hike will not be a burden on consumers.
