भारत के कई शहरों में वायु प्रदूषण बेहद खतरनाक स्तर तक पहुँच चुका है और ऐसे में गाड़ियों से होने वाले प्रदूषण को नियंत्रित करने की ज़रूरत लंबे समय से महसूस की जा रही थी। वाहनों की संख्या काफी अधिक होने के कारण राजधानी दिल्ली में वायु प्रदूषण का स्तर देश में सबसे अधिक है। दिल्ली में वाहनों की संख्या 1 करोड़ से अधिक है, जिनमें से 60% डीज़ल वाहन हैं। ऐसे में दिल्ली में प्रदूषण की समस्या गंभीर है। इसके मद्देनज़र सरकार ने 'क्लीन फ्यूल' कहलाने वाले BS-6 मानकों को वर्ष 2020 से पूरे देश में लागू करने की योजना के क्रम में 1 अप्रैल से इसकी शुरुआत दिल्ली से की है।

Supreme Court order barring sale of Bharat Stage IV vehicles from April 1, 2020 will impact automakers as well as buyers. While the Centre had announced the April 1, 2020 deadline for adopting Bharat Stage VI emission norms, the Supreme Court was deciding whether grace period should be given to automakers for the sale of BS-VI non-compliant vehicles after the deadline. It refused to grant any grace period. BS-IV compliant vehicles were made compulsory from April 1, 2017 while the government had planned to skip the fifth stage and jump to Bharat Stage VI from 2020.
What are Bharat Stage norms?
The Bharat Stage are standards instituted by the government to regulate emission of air pollutants from motor vehicles. The norms were introduced in 2000. With appropriate fuel and technology, they limit the release of air pollutants such as nitrogen oxides, carbon monoxide, hydrocarbons, particulate matter (PM) and sulphur oxides from vehicles using internal combustion engines. As the stage goes up, the control on emissions become stricter. Thus Bharat Stage VI norms are two stages ahead of the present Bharat Stage IV norms in regulating emissions. These norms are based on similar norms in Europe called Euro 4 and Euro 6.
Differences between two stages
The extent of sulphar is the major difference between Bharat Stage IV and Bharat Stage VI norms. BS-IV fuels contain 50 parts per million (ppm) sulphur, the BS-VI grade fuel only has 10 ppm sulphur. BS VI can bring PM in diesel cars down by 80 per cent . The new norms will bring down nitrogen oxides from diesel cars by 70 per cent and in petrol cars by 25 per cent. BS VI also make on-board diagnostics (OBD) mandatory for all vehicles. OBD device informs the vehicle owner or the repair technician how efficient the systems in the vehicle are.
Impact on automakers
Compliance with BS-VI norms will require higher investment in technology to upgrade vehicles in stock and making new vehicles. This will also mean fewer launches till the deadline.
Impact on buyers
Those who buy Bharat Stage VI-compliant vehicles will have to pay more since such vehicles will cost automakers more and they will pass on the additional cost to the buyers. The Bharat Stage VI-compliant fuel too will be more expensive. Oil companies have already begun selling fuel complying with new emission standard in Delhi. The companies are working on meeting the instruction by the Supreme Court to make available BS-VI fuel to 13 metro cities besides the national capital region by April 2019. State companies don’t plan to recover the incremental cost incurred in producing higher grade fuel from customers immediately but may do so after April 2020 when the BS-VI petrol and diesel begin selling across the country.
