Syllabus:
GS Paper – 3
Environmental Pollution & Degradation ,Renewable Energy 2nd ARC
Why in the News ?
● India has achieved 20% ethanol blending (E20) five years ahead of the National Policy on Biofuels target.
● From 1.5% in 2014 to 20% in 2025, ethanol blending has grown rapidly, backed by government support.
● While projected as a win for farmers, environment, and import reduction, the policy faces serious challenges in agriculture, consumer acceptance, and environmental sustainability.
Ethanol Blending: Progress and Policy Push
● E20 Petrol: Petrol mixed with 20% ethanol, rolled out by Indian refiners.
● Policy Support:
○ National Policy on Biofuels (2018, revised 2022) advanced the E20 target to 2025.
○ Fiscal incentives for sugarcane and ethanol industries.
● Achievements:
○ Ethanol blending rose from 1.5% (2014) to 20% (2025).
○ India saved ₹1.40 lakh crore foreign exchange since 2014-15.
○ CO2 emissions reduced by 700 lakh tonnes, according to the Ministry of Petroleum and Natural Gas.
● Supply Growth:
○ Sugarcane-based ethanol rose from 40 crore litres (2014) to 670 crore litres (FY24).
○ Rice and corn also being diverted for ethanol.
About National Policy on Biofuels :
● National Policy on Biofuels (2018, revised 2022) – target: 20% ethanol blending by 2025, achieved early.
● Fair and Remunerative Price (FRP) – assured price mechanism for sugarcane farmers.
● Ethanol Blending Programme (EBP, 2003) – initiated with 5% blending.
● National Electric Mobility Mission Plan (2013) – framework for EV adoption.
● FAME I & II Schemes – incentives for EVs.
● Paris Agreement (2015) – India’s NDCs: 33–35% emission intensity reduction by 2030.
● Net Zero Target – India pledged to achieve net zero by 2070 (Glasgow COP26).
● Water Context: Sugarcane needs 1,500–3,000 mm rainfall, but much of India relies on irrigation → links to Groundwater Act, 2005 (regulation).
● Articles 39(b) & 47 – Directive Principles supporting sustainable resource use and nutrition (food vs. fuel debate).
Public and Industrial Response
● Vehicle Compatibility:
○ Since 2023, new vehicles sold carry E20-compatible stickers.
○ Older vehicles may face issues with rubber, elastomers, and plastic components.
● Consumer Concerns:
○ Local Circles survey: 2 in 3 petrol owners oppose E20 mandate.
○ Concerns: drop in mileage, higher maintenance cost.
● Government’s Stand:
○ Admits “marginal drop” in efficiency but insists it can be fixed with better engine tuning.
○ Minister Hardeep Singh Puri dismissed opposition as a “vilification campaign” by vested interests.
○ NITI Aayog recommended tax incentives on E10 and E20 to compensate consumers.
● Public Sector Oil Companies (PSUs):
○ Despite saving on imports, PSUs passed only 2% reduction in petrol prices to consumers, despite a 65% fall in oil prices since 2022-23.
Agriculture and Environmental Concerns
● Sugarcane Dependence:
○ One tonne sugarcane needs 60–70 tonnes of water.
○ Most sugarcane-growing areas (e.g., Maharashtra) rely on groundwater extraction.
○ Sugarcane accounts for 9% of India’s sugar output being diverted for ethanol.
● Water Stress:
○ 2023 Central Groundwater Board report: sugarcane districts extract more water than non-sugarcane areas.
○ 30% of India’s land degraded (Desertification and Land Degradation Atlas 2021).
● Diversification Efforts:
○ Rice allocation for ethanol jumped to 5.2 million metric tonnes in 2024-25.
○ Corn: 34% diverted to ethanol, forcing 9.7 lakh tonnes of corn imports (6x rise from last year).
● Farmer Incentives:
○ ₹1.20 lakh crore paid to farmers since FY15.
○ Fair and Remunerative Pricing (FRP) ensures sugarcane’s steady profitability, making diversification harder.
● OECD-FAO projection: By 2034, 22% of India’s sugarcane will go to ethanol.
Global Reactions and Trade Tensions
● U.S. Concerns:
○ The U.S. Trade Estimate Report (2025) calls India’s restrictions on ethanol imports a “significant trade barrier.”
○ The Trump administration pushing India to relax restrictions.
● Indian Sugar Mills Association (ISMA): Strongly opposes import relaxation → would undermine domestic ethanol industry built over a decade.
● Geopolitical Angle: India’s ethanol boom is seen as strategic autonomy in energy but may face WTO disputes if protection continues.
5. Ethanol vs. EV Transition
● Emission Savings:
○ Ethanol blending reduced 700 lakh tonnes CO2.
○ But EV adoption offers greater long-term emission cuts.
● Slow EV Adoption in India:
○ EVs = 7.6% of sales in 2024, target is 30% by 2030.
○ Needs 22% annual growth in next 5 years.
● Barriers:
○ Rare Earth Element (REE) dependency – crucial for batteries and motors.
○ China dominates REE supply → India vulnerable.
○ Example: Maruti Suzuki cut EV targets due to REE shortages.
● Global Comparison:
○ U.S., EU, China → EV adoption far ahead.
○ Beijing’s air quality improved largely due to rapid EV shift.
● Policy Dilemma:
○ Push ethanol blending beyond 20% OR accelerate EV adoption?
○ Government signals mixed; no final decision yet.
Challenges :
● Consumer Resistance: E20 adoption unpopular due to lower mileage and higher costs.
● Environmental Sustainability:
○ Sugarcane is water-intensive.
○ Causes groundwater depletion and land degradation.
● Food vs. Fuel Dilemma: Diversion of rice and corn risks food security and raises import bills.
● Unequal Benefits: Farmers benefit from assured FRP payments, but consumers see little petrol price relief.
● Energy Policy Confusion: Lack of clarity on whether to expand ethanol blending beyond 20% or shift focus to EVs.
● EV Barriers: REE shortage, high costs, weak charging infrastructure.
● Global Pressure: U.S. pushing for ethanol import liberalisation, risking domestic producers.
● Long-term Climate Goals: Ethanol alone cannot deliver net-zero targets; must integrate with EVs + renewables.
Way Forward :
● Balanced Approach: Ethanol blending should complement, not substitute, EV transition.
● Diversify Feedstock: Move beyond sugarcane → encourage maize, sorghum, cellulosic ethanol.
● Water-Smart Policies: Incentivise farmers for drip irrigation, crop diversification, water-efficient crops.
● Consumer Relief:
○ Introduce tax incentives for E20 use.
○ Ensure PSUs pass fuel savings to the public.
● Strengthen EV Ecosystem:
○ Invest in charging infra, battery R&D, and REE exploration in India.
○ Secure rare earth supply chains via diplomacy and FTA agreements.
● Global Strategy: Maintain ethanol import restrictions to protect domestic industry.
● Policy Clarity: Government must signal if the future strategy is high-blend ethanol (E85) or EV dominance.
● Integrated Climate Action: Combine ethanol blending, EV adoption, and renewable energy growth for sustainable decarbonisation.
Conclusion :
Ethanol blending has given India foreign exchange savings, farmer support, and emission reductions. Yet, over-reliance on water-intensive sugarcane and consumer backlash highlight its limits. A balanced approach, integrating ethanol with EV adoption and renewable energy, is essential to ensure sustainable growth and align with India’s net-zero 2070 goal.

Mains Practice Question :
“Critically examine the impact of ethanol blending on India’s energy security, agriculture, and environmental sustainability. Discuss whether ethanol can be a transitional solution or if the long-term strategy should prioritize electric mobility and renewable energy.”
