The push for E20
India is set to roll out 20 per cent ethanol-blended petrol, a move the government has defended as beneficial for energy security and the environment. The NDA government has highlighted that the programme's seeds were sown earlier, with the pilot launched during AB Vajpayee's government in 2001 and an attempted E5 rollout in 2006 under the UPA. The current government has overseen its acceleration, with blending reaching 10 per cent in 2021-22, rising to 19.2 per cent in 2024-25, and now set at the target of 20 per cent.
Proponents point to the myriad advantages of ethanol blending: it cuts fossil fuel use, produces lower carbon emissions, curbs import dependence, saves foreign exchange, and insulates the country from supply disruptions. Yet, as The Indian Express reports, these macroeconomic benefits have not translated into perceived gains for the average consumer.
The choice deficit
A government officer explained to The Indian Express that the consumer sees no tangible price benefit despite bearing the cost of lower mileage. The root cause, the officer argued, is the absence of choice--consumers cannot opt for a different blend if they are unhappy with the cost-benefit ratio of E20.
The argument draws a parallel with the income-tax regime. When a new tax regime was introduced in April 2020, it was made voluntary. Taxpayers were allowed to choose between the old regime with its exemptions and the new one with lower rates. This choice, according to the article's analysis, was a model of consumer-centric policy.
A free-market solution?
To address this, a suggestion has been put forward to offer E5, E10, and E20 alongside pure petrol, with differential pricing as an incentive. Under this model, E20 would be priced lower than E10, allowing consumers to make peace with a 3-5 per cent lower mileage because of the cheaper fuel. This approach, the argument goes, would convert a mandatory switch into an informed choice.
A practical illustration of this would be to offer E5 alongside regular petrol, letting consumers decide if the price differential justifies the mileage difference. This mirrors the success of the income-tax reform, where the majority opted for the new regime, but crucially, the choice was theirs.
The article argues that this consumer-centric approach could smooth the transition to E20, turning a potentially contentious policy into a smooth, market-driven shift.
Broader context and international comparisons
Government comparisons highlight the relative stability of Indian fuel prices. Between June 2022 and June 2026, petrol prices rose less than 6 per cent in India, according to the government's calculations, while European and South Asian countries saw hikes exceeding 15 per cent and 20 per cent, respectively. This price stability is a key plank of the government's defence.
However, the article notes that the benefits of E20 were more easily defensible when global crude oil prices were high. When the Indian crude oil basket averaged over $100 a barrel, E20 helped keep petrol prices low, a counterfactual that is hard for consumers to grasp. Government estimates indicate that at global crude prices of $70 a barrel or less, E20 is actually costlier to produce than pure petrol, whereas it becomes much cheaper at $120-130 a barrel.
The road ahead
The transition from E10 to E20 has been rapid, completed in just four years [compared to the decade it took to reach E10]. This speed may have been driven by concerns about geo-political crises, particularly in West Asia, pushing oil prices higher for longer.
While the policy has clear benefits, the article argues that its sustainability depends on addressing consumer concerns. The key takeaway is that transparency and consumer choice could be the most effective tools for building public support for the E20 programme.
