India's Ethanol Ambition: Energy Cure or Ecological Gamble?

Synopsis

The Ethanol Blended Petrol (EBP) programme was able to reach the 20% blending target five years early in November 2025. The drive, based on the National Policy on Biofuels 2018, has helped the country to save more than ₹1 lakh crore of foreign exchange, create rural incomes and also reduce carbon emissions significantly. However, issues of food diversion, water availability, engine fuelability, and over-supply of distillery capacity are also becoming focal points for policy consideration as targets move towards E30 and beyond.

A 10-year wager that has paid off... So far

Ramesh Tiwari, a sugarcane farmer from Lakhimpur Kheri, Uttar Pradesh was told in 2019 that his surplus cane would be sold in petrol pumps and he was doubtful. His income had risen by almost 30 per cent by 2024, when the government guaranteed him procurement prices and assured him offtake from oil marketing companies. His story is not an atypical one.

In 10 years, the ethanol blending programme has directly benefitted farmers with ₹ 87,558 crore and ₹ 1,45,930 crore to distilleries. The blending rate of 1.53% in 2013–14 is one of the world's most ambitious biofuel mandates.

In November 2025, India achieved 20% ethanol blending ahead of the national target date, and E20 fuel was made mandatory on 1 April 2026 in all States/Union Territories (UT).

The Strategic Case: Why India Made This Bet

The maths behind the policy is quite simple. India is dependent on crude oil imports to the extent of over 85%. Each per cent of ethanol taking the place of petrol decreases that reliance and the foreign exchange costs associated with it.

The programme has saved ₹1,06,072 crore in foreign exchange, saved 181 lakh metric tonnes of crude oil and saved 544 lakh metric tonnes of CO2 emissions in the last decade.

The E20 blending is estimated to have reduced CO2 emissions by around 832 lakh metric tonnes with only E20, which has taken India a giant step towards achieving the Net-Zero by 2070 target.

Ethanol use is designed as a 'drop-in' fuel, one that can be used with existing internal combustion engines, meaning that the system would not require an overhaul as a complete electric transition would require.

The ethanol market in India is expected to increase at a compound annual growth rate of 13.95% and reach USD 11.8 billion by 2034 from USD 3.4 billion in 2025.

The Rural Economy Dividend

The programme has a significant rural impact. The entire ethanol procurement under 2025 was estimated to generate revenue of ₹1.18 lakh crore to the farmers and ₹1.96 lakh crore to the distilleries, which was equivalent to making India's farmers Urjadaatas (energy providers) and Annadatas (food providers).

The demand for sugarcane, maize and rice has opened up a guaranteed market for farmers, the programme claimed it had brought more than ₹1.58 lakh crore in direct income to the farmers. The creation of new jobs in agro-processing has been focussed in the states where rural underemployment is most severe, such as Uttar Pradesh, Maharashtra and Bihar.

When the Cracks appear: Food Security Dilemma

The most significant vulnerability of the programme is its reliance on food crops. The allocation of rice for ethanol was set as 90 lakh tonnes for 2025-26 compared with 52 lakh tonnes previously. For this, the government was thinking of cutting down the proportion of broken rice provided to the poor through the public distribution system from 25% to 10%.

Not since a couple of months in January 2022 has food inflation in India been below the Reserve Bank of India's comfort level of 4% at the retail level, suggesting any diversion of staple grains for fuel production would be a politically and nutritionally sensitive issue.

The Water Audit That Policy Has Avoided

The NITI Aayog and Ministry of Petroleum and Natural Gas roadmap shows that a sugarcane requires 1600 to 2100 liters of water to grow and make one kg of sugar, which translates to 3000 liters of water needed for one litre of ethanol made from sugarcane. There is about 4,000 litres required for every 1 kg of rice grown.

Sugarcane has less than 10% of the area in Maharashtra but uses an undue amount of water for irrigation. Increased ethanol-related crops may exacerbate water deficits in the region.

Concurrently, hundreds of assessment units in India were identified as over-exploited, critical or semi-critical in the Central Ground Water Board's 2025 assessment, which is problematic against the backdrop of plans to increase the production of ethanol.

The Engine in the Room: Consumer and Vehicle Costs

The energy density of ethanol is less than that of petrol, so the amount of fuel needed to travel the same distance would be greater, and efficiency can be reduced by around 6–7% in non-compatible engines. Fuel-system corrosion, rubber seal and fuel line degradation, and decreased engine durability (especially in older cars) are all potential issues with higher ethanol blends.

The high cost of Flex Fuel Vehicles, that are able to use higher ethanol blends, and also lack clarity on consumer uptake, could mean that a significant part of India's vehicle fleet will incur hidden maintenance costs as the blending targets increase.

The Surplus Distillery Problem

By November 2025, India's installed ethanol production capacity was well above the requirement for E20, with a capacity of 20 billion litres. This has posed a new policy dilemma: if the distilleries are not used, they have high fixed costs, lower returns and the potential to become stranded assets.

There is concern that future blending targets might not only be based on environmental or strategic value but also to maintain economic viability of the surplus infrastructure.

The Road to E30 and Beyond

In January 2025, Pankaj Jain, the Secretary of the Ministry of Petroleum and Natural Gas, confirmed in a meeting that a dedicated committee was already working on ways to go beyond 20% blending. “We are on the path to achieve E20 before schedule, and now we are going to build the ecosystem for going beyond E20,” he said.

The next generation — 2G ethanol from agricultural residues like paddy straw — is theoretically considered to address the food-versus-fuel dilemma. 2G and 3G biofuel production through scale-up could help alleviate the stubble-burning problem, that envelops North Indian cities in smoke every winter. However, the technology to produce 2G sugarcane ethanol is commercially infant in India and is still very expensive in comparison to the cost of 1G.

The Verdict

India's ethanol policy has indeed achieved a lot of tangible results with regards to energy security, rural income and carbon reduction and these are commendable. However, the programme is now in a stage where the low hanging fruit is being picked. While the "real" costs of the feedstocks that drive E10 and E20 are at least thirsty crops, diverted grains and engines designed for the previous fuel but being asked to burn something different, these costs have not been considered.

It remains to be seen whether India's ethanol push will be an actual energy transition or a classic example of policy overreach in the following two years, as the government considers 2G investment, water usage accounting and compatibility of vehicles with ethanol. The nozzle of the pump has been changed, the hard policy work has just begun.
