A political grenade landed on India's ethanol blending programme Friday when AAP National Convenor Arvind Kejriwal publicly labelled the government's push to roll out E20 fuel — petrol blended with 20% ethanol — a 'full blown scam,' demanding to know why Prime Minister Narendra Modi is pressing ahead despite vocal opposition from consumers and technical experts.

What E20 is and why it became a flashpoint

India's National Policy on Biofuels, 2018 set a target of achieving 20% ethanol blending in petrol by 2030. The Ethanol Blended Petrol programme itself dates to 2003, with successive governments — across party lines — ratcheting up the targets through 2015 and again in 2021, framing the policy as a triple win: cutting costly crude oil imports, channelling extra revenue to sugar mills, and trimming vehicular emissions.

But the policy has never been controversy-free. Vehicle owners and automotive engineers have raised persistent concerns about real-world mileage losses on E20 blends, engine compatibility for older vehicles, and effective price parity at the pump. Those concerns form the backdrop to Kejriwal's broadside.

Kejriwal's 'scam' charge and what he is asking

In his post on 14 August 2026, Kejriwal did not allege a specific financial irregularity but framed the government's urgency itself as the red flag — asking 'why' Modi is 'soooo desperate' to impose E20 when consumers and experts are criticising it 'vociferously.' The rhetorical move is deliberate: it shifts the burden of explanation onto the government rather than presenting counter-evidence, a classic opposition pressure tactic.

The word 'impose' is doing significant work here. Kejriwal frames E20 not as a phased policy transition but as something being forced on an unwilling public — a framing that aligns with the concerns of petrol consumers and vehicle owners who worry about performance and cost.

The stakeholders caught in the middle

The E20 debate has always had competing interests in tension. Sugarcane farmers and sugar mills stand to gain from higher ethanol offtake, giving the policy a rural-agricultural constituency that successive governments have been reluctant to alienate. On the other side sit urban vehicle owners — a large, vocal, and politically sensitive group — who have flagged mileage drops and uncertainty over whether older engines can handle higher ethanol concentrations without modification.

Energy security advocates argue that every percentage point of domestic ethanol blended is one less barrel of imported crude — a balance-of-payments argument that carries real weight given India's chronic oil import bill. The government has consistently led with this logic. Kejriwal's post, by calling the urgency a 'scam,' challenges whether that logic is the real driver.

What the government has not yet answered publicly

The specific rationale for the pace of the 2026 E20 expansion — why now, at this speed, over consumer objections — has not been detailed in verified public statements available at the time of this report. That gap is precisely the space Kejriwal is occupying. His post is less a policy counter-proposal than a demand for transparency, and it will keep pressure on the government to articulate, clearly and publicly, the cost-benefit case for E20 at this moment.

As E20 pumps expand nationwide and technical studies on vehicle performance accumulate, the political argument around ethanol blending is only going to get louder — and more specific.
