India's ethanol blending programme has a history stretching back more than two decades and the shift to E20 — blending 20 per cent ethanol in petrol — was grounded in years of technical testing, stakeholder consultations and phased infrastructure development, the Petroleum Ministry stated on Friday, 10 July. The ministry pushed back against claims that the transition was rushed, calling such suggestions 'simply not borne out by facts.'

A Timeline Rooted in UPA-Era Policy

The ministry's detailed statement made clear that the foundations of the programme predate the current government. A pilot ethanol blending initiative was launched in 2001, formally announced in 2004, and E5 (5 per cent blending) was rolled out across several states by 2006. The policy framework was subsequently notified in the Gazette of India in January 2013 during the UPA government — 'matters of public record,' the ministry said.

Despite a target of achieving 5 per cent blending across 10 states and union territories, actual blending remained stuck at around 1.5 per cent until 2014, the ministry noted. The core constraint at the time was not policy intent but supply: India depended almost entirely on sugarcane, a seasonal crop, with an annual ethanol production capacity of roughly 400 crore litres — inadequate even for modest blending targets.

The Post-2018 Scale-Up

A structural shift came with the National Policy on Biofuels launched in May 2018, which the ministry described as the beginning of a 'genuine whole-of-government mission.' The Ministry of Petroleum and Natural Gas, the Department of Food and Public Distribution, the Ministry of Road Transport and Highways, the Ministry of Heavy Industries, Indian Railways, and several other departments coordinated to expand feedstocks, build infrastructure, align logistics and attract investment.

A landmark step followed in August 2021, when Oil Marketing Companies — IOCL, BPCL, and HPCL — issued expressions of interest for establishing Dedicated Ethanol Plants (DEPs) in ethanol-deficit regions. These projects offered assured long-term purchase agreements, tripartite financing arrangements with public sector banks through escrow mechanisms, and a mandatory supply commitment exclusively for the Ethanol Blended Petrol Programme.

Separately, in June 2021, NITI Aayog published a comprehensive ethanol blending roadmap following extensive consultation with automobile manufacturers, oil companies, and agricultural experts. The report highlighted environmental, energy-security and rural-income benefits of scaling up blending.

Why E20 Was a Logical Next Step

With 10 per cent blending requiring 500–600 crore litres annually, expanding production capacity to nearly 1,200 crore litres made a higher blending target both viable and responsible, the ministry argued. 'Once the supply side had been secured, it became both logical and responsible to aspire for 20 per cent blending,' the statement said.

Before E20 was rolled out, multiple rounds of detailed consultations were held with automobile manufacturers, technical experts, and testing agencies to ensure readiness across the ecosystem. Maruti Suzuki serviced 2.84 crore vehicles during FY 2025-26 — including 1.5 crore older, non-E20-certified vehicles — and reported no E20-linked corrosion, abnormal wear, or component-life damage. Hero MotoCorp reported similar field experience. The ministry called this real-world evidence 'far more reliable than isolated anecdotes.'

Quality Controls and Zero Tolerance for Adulteration

The ministry advised consumers not to be misled by 'misinformation, scaremongering or unverified content circulating on social media,' stating that ethanol and blended petrol conform to strict Bureau of Indian Standards (BIS) specifications and undergo quality checks at every stage — from the distillery to the depot to the retail outlet.

'Any procedural lapse anywhere in the supply chain should be dealt with firmly. Chief Secretaries of the states have been requested to ensure strict enforcement and take an iron hand against any instance of adulteration. There can be zero tolerance for lapses that compromise fuel quality,' the ministry stated.

The programme now represents a journey spanning over two decades — from pilot projects in 2001 to policy notification in 2013, institutional reforms after 2018, major investments from 2021, and a phased increase in blending levels that the ministry insists has been carefully calibrated at every step.
