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.”
