New Delhi will follow an 'odd-even' scheme for five days starting Monday in which cars will be allowed on the roads based on whether their number plates are odd or even. Photo: PTINew Delhi: The Bureau of Indian Standard (BIS) has revised the Indian standards on petrol (IS 2796) and diesel (IS 1460) as per BS VI fuel norms, an official statement said here Wednesday.
So far, these standards covered fuel requirements based on emission norms up to BS IV.
With a view to conserve natural resources as well as to reduce pollution, government has decided to implement BS VI emission norms in Delhi NCR from April 1, 2018. In rest of the country these will be implemented from April 1, 2020.
"The revised standards will improve the environment and reduce respiratory problems due to reduction in permissible sulphur content which will also reduce emission of nitrogen oxides," the statement said.
These standards also permit increased blending of ethanol in petrol and bio-diesel in diesel which will help in conservation of natural resources and reduction in import of crude.
