India ethanol blending dispute erupts between Karnataka and Centre

A significant dispute has emerged between the Karnataka state government and the Indian central government regarding the ethanol content in E20 petrol. The Karnataka government, led by Chief Minister DK Shivakumar, alleges that laboratory tests on samples from seven districts revealed ethanol levels as high as 31.2 per cent, far exceeding the mandated 20 per cent limit. The state claims thousands of motorists have reported vehicle issues, including reduced mileage and engine malfunctions, due to this alleged adulteration.

The Ministry of Petroleum and Natural Gas and major oil marketing companies (OMCs), including Indian Oil Corporation (IOCL), Bharat Petroleum (BPCL), and Hindustan Petroleum (HPCL), have rejected these claims. The Centre stated that 893 samples tested across 27 states and Union Territories all complied with the prescribed 19 to 21 per cent range. The OMCs have questioned the validity of the Karnataka government's testing methodology, citing procedural lapses and a lack of certified documentation.

Politically, the issue has drawn sharp criticism from Congress leader Rahul Gandhi, who accused the government of cheating the public. In response, BJP leaders have defended the E20 programme and questioned the accuracy of the state's findings. Meanwhile, the Kerala government has ordered its own inspections following the controversy in Karnataka.
