India’s growing commitment to biofuels is drawing global attention as world leaders discuss sustainable energy at the ongoing climate summit. The country’s recent success in achieving its 20% ethanol-gasoline blending target five years ahead of schedule highlights both the promise and complexity of transitioning to cleaner fuels.
India has joined Brazil, Japan, and Italy under the “Belem 4x” initiative an agreement aimed at quadrupling global sustainable fuel use by 2035. The initiative, discussed at the COP30 summit, has already gained support from 19 countries. Brazil, a long-standing leader in ethanol production, currently uses a 27% blend and plans to increase it further.
Brazil’s Secretary for Climate, Energy, and Environment, Mauricio Lyrio, praised the growing global commitment, saying the diverse participation “shows that the cause resonates across the world.”
India’s Ethanol Shift: Opportunities and Challenges
India’s rapid adoption of ethanol has been hailed as a success in cutting emissions and reducing oil imports. According to government data, ethanol blending has saved over $12 billion in foreign exchange and reduced carbon emissions by 74 billion kilograms comparable to planting 300 million trees.
However, the transition hasn’t been seamless. Many drivers have reported decreased fuel efficiency and issues with older vehicle engines. “I support clean energy,” said Vijay Ramakrishnan, a businessman from Chennai. “But the drop in mileage has made my daily commute more expensive.”
Automotive expert and YouTuber Amit Khare noted similar complaints from his viewers, saying that while lower blends like E5 and E10 are manageable, the E20 mix has caused significant engine problems in some vehicles. Experts such as Ramya Natarajan from the Center for Study of Science, Technology and Policy agree that ethanol can reduce mileage unless vehicles are specifically designed for higher blends.
Farmers Seek Direction on Crop Policies
The shift toward ethanol has also affected India’s agricultural landscape. In Punjab, farmer Ramandeep Mann said many growers planted more corn last year, expecting to sell it for fuel production. However, prices dropped after the government began diverting rice stocks for ethanol manufacturing.
India’s ethanol supply has traditionally come from sugarcane, but grain-based ethanol is now dominant. This shift has led to uncertainty among farmers, as prices for sugarcane and corn fluctuate with government policy. “It’s good that the government is addressing climate change,” Mann said, “but farmers’ livelihoods should not suffer because of ethanol mandates.”
Natarajan added that expanding ethanol cultivation could reduce land available for food crops. “As blending targets increase, more farmland will be needed for fuel production, which may displace other essential crops,” she explained.
Balancing Energy Goals with Sustainability
Experts emphasize that biofuels are most sustainable when derived from waste materials or non-edible plants and processed with renewable energy. However, producing ethanol from food crops increases emissions due to fertilizer use and energy-intensive farming.
Purva Jain, an energy specialist at the Institute for Energy Economics and Financial Analysis, said ethanol is just one part of India’s broader energy strategy to cut carbon emissions and reduce oil dependence. Yet, she believes electric vehicles powered by solar energy could offer a more efficient long-term solution. “Solar-powered EV infrastructure makes better use of land than cultivating crops for ethanol,” she noted.
Still, industry leaders argue that India must continue supporting ethanol producers. “We’ve invested heavily in manufacturing,” said C.K. Jain, president of the Grain Ethanol Manufacturers Association. “If blending targets don’t rise soon, the industry could face severe financial challenges.”
The Road Ahead
Experts suggest a balanced approach — maintaining a 10% ethanol blend could offer a “win-win” outcome. It would support biofuel development without putting excessive pressure on agriculture or vehicle owners.
Khare, the auto influencer, echoed this view: “It’s fine to promote E20 or even E85 for compatible cars, but consumers should always have the option to choose lower blends.”
As India pushes forward on its green energy path, its ethanol story serves as a case study for other nations — a mix of ambition, innovation, and the need for balance between sustainability, affordability, and practicality.
