Bhutan’s motors would become more environment-friendly from 2017 when the country starts importing Euro IV graded petroleum products, replacing Euro III currently being imported.
A Memorandum of Understanding (MoU) has been signed between the government of Bhutan and Indian Oil Corporation (IOL) last week. The MoU states that IOC will meet the entire requirement to the dealers as appointed by trade department of Bhutan.
Euro IV fuel is less polluting as it emits less nitrogen oxides, total hydrocarbon, non-methane hydrocarbons, and carbon monoxide gases. Sulphur content in Euro III is 150 ppm (part per million) in petrol and 350ppm in diesel, whereas it is only 50ppm each in petrol and diesel for Euro IV.
The problem of vehicles not starting during the cold winter and spoilage of engine of expensive vehicles could also be minimised with the availability of the better fuel.
