The Technology Has Outrun the Statute Fuel, Farm and the Fundamental Right: A Legal Study of Biofuels on World Biofuel Day
A comparative and constitutional examination of biofuel regulation, with particular reference to India
I. Introduction: Why 10 August
World Biofuel Day is observed on 10 August in commemoration of Sir Rudolf Diesel’s demonstration, in 1893, that a compression-ignition engine could be run on peanut oil. What Diesel treated as a technical curiosity has, in the intervening century and a quarter, become a subject of hard law: blending mandates enforced against oil marketing companies, statutory volume obligations traded as compliance instruments, lifecycle carbon-intensity certification, product-liability exposure for engine damage, and constitutional litigation over whether a citizen may choose what goes into his fuel tank.
For the Indian practitioner, 2025–26 is the moment this subject stopped being policy commentary and became litigable law. India achieved 20 per cent ethanol blending (E20) in 2025 — five years ahead of the target originally set under the National Policy on Biofuels, 2018 — and from April 2026 E20 is, for practical purposes, the standard motor spirit at the pump. The Supreme Court has already dismissed one public interest litigation challenging that rollout; a second, seeking mandatory disclosure and labelling, has been filed. A nine-Judge Bench has, meanwhile, redrawn the constitutional map of who may regulate the very commodity being blended.
This article examines: (II) the taxonomy of biofuels; (III) environmental impact; (IV) impact on human health and on machines; (V) the automobile sector; (VI) the agricultural sector; (VII) a comparative survey of biofuel law across jurisdictions; (VIII) the legal framework governing biofuels in India; (IX) the amendments this author submits are required; and (X) a comparative economic assessment of biofuels against conventional and alternative fuels.
II. The Taxonomy: What the Law Must Classify
Regulation follows classification, and biofuel classification is not uniform across jurisdictions. Broadly:
By generation
Article content
By product
Bioethanol — anhydrous ethanol blended into petrol (E5 to E100). The dominant Indian biofuel.
Biodiesel (FAME) — fatty acid methyl esters from vegetable oils, used cooking oil (UCO), tallow; blended into diesel (B5 to B50).
Renewable diesel / HVO — hydrotreated vegetable oil; a chemical drop-in replacement for diesel, unlike FAME. Legally significant because it escapes most blend-wall constraints.
Compressed Bio-Gas (CBG) / biomethane — upgraded biogas from agricultural residue, press mud,MSW, sewage; injected into CNG/PNG networks.
Sustainable Aviation Fuel (SAF) — via HEFA (from UCO/tallow) or alcohol-to-jet (ATJ), certified to ASTM D7566.
Bio-methanol, bio-butanol, bio-DME, pyrolysis oil, biochar co-products — niche but emerging.
RFNBOs (renewable fuels of non-biological origin) — green hydrogen and its derivatives. Not biofuels strictly, but placed in the same regulatory basket by the EU and increasingly by India’s Green Hydrogen Mission.
The legal point is this: a statute that speaks only of “ethanol and biodiesel” — as India’s policy framework substantially does — will be structurally unable to regulate HVO, SAF, biomethane and e-fuels without repeated executive patching. Definition is the first reform.
III. Impact on the Environment
(a) The greenhouse gas case
The case for biofuels rests on lifecycle accounting: carbon absorbed during feedstock growth offsets combustion emissions. The Government of India’s own figures for the ethanol programme since 2014-15 claim avoidance of the order of 950 lakh tonnes of CO₂, reduction of crude imports by roughly 316 lakh tonnes, and foreign exchange savings crossing ₹1.9 lakh crore.
These figures are gross rather than net. They are computed against displaced petrol volumes; they do not universally net out cultivation emissions, fertiliser nitrous oxide, irrigation energy, distillery process heat, or indirect land-use change (ILUC). The European Union, by contrast, legislates the counterfactual: RED III requires 70 per cent lifecycle GHG saving for existing installations and 80 per cent for new ones, with mandatory certification and mass-balance chain-of-custody. India has no statutory lifecycle threshold at all. A litre of ethanol from FCI rice grown on tubewell-irrigated land in a dark-zone block receives identical legal treatment to a litre from bagasse. That is a regulatory defect, not a technical one.
(b) Water — the Indian programme’s most serious environmental exposure
Figures placed in the public domain by the Food Secretary indicate that a single litre of ethanol requires approximately 10,790 litres of water when produced from rice, about 4,670 litres from maize, and about 3,630 litres from sugarcane — the overwhelming share consumed in cultivation, not in the distillery. NITI Aayog’s Composite Water Management Index and the Central Ground Water Board’s assessments have flagged large parts of Maharashtra, Uttar Pradesh, Karnataka, Punjab and Haryana as over-exploited, critical or semi-critical.
Ethanol capacity has been sited where feedstock is — which is precisely where groundwater is most stressed. Brazil’s cane belt is largely rainfed; India’s is largely irrigated. The comparison that flatters India’s programme on carbon damns it on water.
There is presently no legal instrument linking distillery siting or feedstock eligibility to aquifer status. The Central Ground Water Authority’s NOC regime under Section 5 of the Environment (Protection) Act, 1986 operates project-by-project; it does not operate as a feedstock-eligibility filter.
(c) Effluent, and an instructive Maharashtra precedent
Molasses-based distilleries generate spent wash at roughly 8–15 litres per litre of alcohol, with extremely high BOD/COD. CPCB norms require zero liquid discharge for molasses-based units, but enforcement is uneven.
In March 2026 the National Green Tribunal directed a Kolhapur-based cooperative sugar factory to deposit ₹50.10 lakh as environmental compensation with the Maharashtra Pollution Control Board for discharge of untreated effluent, including molasses-based discharge, into the Hiranyakeshi river. The case is a template: the polluter-pays principle, applied under Sections 15 and 20 of the National Green Tribunal Act, 2010, read with the Water (Prevention and Control of Pollution) Act, 1974, is the most effective present remedy against distillery pollution — and cooperative sugar factories, being the dominant Maharashtra model, are the natural respondents.
(d) Air quality — a mixed record
Ethanol blending reduces carbon monoxide, unburnt hydrocarbons and particulate matter, and raises octane (E20 fuel is specified at a minimum RON of 95). Against this must be set increased evaporative emissions of volatile organic compounds in hot climates, and elevated acetaldehyde and formaldehyde in the exhaust — aldehydes being probable human carcinogens and ozone precursors. Indian emission regulation under the Central Motor Vehicles Rules, 1989 does not separately regulate aldehyde emissions in the way Brazilian PROCONVE norms have historically done. That gap will become material as blends rise toward E85 and E100.
(e) Biodiversity and land
Palm-based biodiesel (Indonesia, Malaysia) and soy-based biodiesel (Brazil, Argentina, the United States) carry deforestation and ILUC exposure. The EU’s high-ILUC delegated regime effectively phases out palm; several member States have gone further. India’s exposure is different in kind: not deforestation, but monocropping, the displacement of pulses and oilseeds by cane and maize, and soil degradation —problems of agricultural rather than forest law.
IV. Impact on Man and Machine
(a) Human health and occupational exposure
Ethanol combustion improves urban CO and PM profiles, which is a genuine public-health gain in cities such as Delhi, Kanpur and Mumbai. Countervailing exposures — aldehyde formation, VOC evaporation at retail outlets, and occupational exposure of distillery and tanker workers to ethanol vapour and effluent — are governed by the Factories Act, 1948, the Petroleum Rules, 2002 (ethanol being a Class ‘A’ petroleum by flash point), and PESO licensing. These are administered as safety law, not as public-health law, and no aggregated epidemiological monitoring of the blending programme exists.
(b) Machines: the compatibility question
This is where biofuel law meets private law. Ethanol is hygroscopic, mildly corrosive to certain metals (aluminium, zinc, brass), and aggressive toward older elastomers, gaskets and fuel-line materials. It carries roughly 28 per cent lower gross calorific value than petrol. Vehicles not calibrated for the blend can suffer:
- Fuel efficiency loss. Government and industry sources place the loss for E10-designed vehicles running E20 at roughly 3–6 per cent; independent analyses using calorific-value arithmetic put per-litre economy loss at 20–25 per cent on E100 in flex operation. Both can be true — they measure different blends.
- Material degradation in pre-2023 vehicles: fuel pumps, injectors, seals, rubber hoses, carburettor components in older two-wheelers.
- Phase separation where water ingress occurs in storage, particularly in coastal and monsoon conditions. Manufacturers have publicly reported that large service datasets show no measurable increase in E20-related failures, including among vehicles never certified for E20. That evidence is significant but it is manufacturer-generated, it addresses failure incidence rather than accelerated wear over full vehicle life, and it has not been tested in adversarial proceedings.
(c) The consequential legal exposures — the practitioner’s real subject
Warranty. Where an owner’s manual specifies a maximum blend (commonly E10 for pre-2023 vehicles) and the only fuel lawfully available at the pump exceeds it, a warranty repudiation for “use of non-specified fuel” is arguably unsustainable. The doctrine of lex non cogit ad impossibilia applies: no one is bound to do the impossible, and a consumer cannot be penalised for using the only fuel the State permits to be sold.
Insurance. The same reasoning applies to repudiation of own-damage claims on the ground of fuel non-compliance. IRDAI has issued no clarificatory direction; the point is open and eminently litigable before Consumer Commissions and the Insurance Ombudsman.
Product liability. Chapter VI of the Consumer Protection Act, 2019 (Sections 82–87) creates productliability actions against manufacturers, sellers and service providers. Whether an oil marketing company is a “product seller” of a defective “product” where the defect lies in statutorily mandated composition, and whether the mandate affords a defence, is untested.
Right to information as a consumer right. Section 2(9)(ii) of the Consumer Protection Act, 2019 confers on consumers the right to be informed of the quality, quantity, potency, purity, standard and price of goods. Absence of ethanol-content declaration at the dispensing unit is, on the face of it, a denial of that right, potentially also an unfair trade practice under Section 2(47).
(d) The constitutional litigation to date
In September 2025 a Bench of the Chief Justice and Justice K. Vinod Chandran declined to entertain a PIL (filed by Advocate Akshay Malhotra, argued by Senior Advocate Shadan Farasat) which sought the parallel availability of ethanol-free petrol for pre-2023 vehicles, mandatory labelling of ethanol content at pumps, and a nationwide impact study. The petition relied on a 2021 NITI Aayog report flagging efficiency loss, corrosion and accelerated wear, and on the consequential warranty and insurance exposure. The Union, through the Attorney General, defended the policy on grounds of farmer benefit, energy security and forex savings. The Court declined to interfere with what it treated as a policy decision forming part of a national energy strategy.
In July 2026 a fresh writ petition (Narender Kumar Goswami v. Union of India) was filed, expressly disclaiming any challenge to the blending policy itself and confining relief to mandatory disclosure of ethanol content at pumps and on invoices, publication of a vehicle-wise compatibility database, and safeguards for legacy-vehicle owners — preceded by a representation to the Ministry of Petroleum and Natural Gas in July 2026.
The doctrinal shift is instructive and worth internalising. The first petition attacked the mandate and lost on the settled ground that courts do not sit in appeal over economic policy (Balco Employees’ Union v. Union of India, (2002) 2 SCC 333; Bhavesh D. Parish v. Union of India, (2000) 5 SCC 471). The second attacks the absence of procedural safeguards accompanying the mandate — information, choice, compatibility disclosure. That is not policy review; it is Article 14 arbitrariness and Article 19(1)(g)/21 proportionality analysis applied to the manner of implementation, and it engages the Maneka Gandhi and K.S. Puttaswamy proportionality line. Counsel advising in this space should note that the second framing is the surviving one.
V. Impact on the Automobile Sector
(a) The regulatory instruments
Vehicle-side biofuel regulation in India runs through the Motor Vehicles Act, 1988 and the Central Motor Vehicles Rules, 1989 (type approval, emission compliance, conformity of production), read with Indian Standards notified under the Bureau of Indian Standards Act, 2016 — principally IS 2796 for motor gasoline and IS 17586 for E20 fuel, with IS 15607 for B100 biodiesel.
(b) The 2026 movement
In April 2026 the Ministry of Road Transport and Highways issued draft amendments to the Central Motor Vehicles Rules to bring E85 and E100 within the vehicle-regulation framework, alongside proposals extending to B100. New fuel standards notified in May 2026 cover intermediate blends including E22, E25, E27 and E30. Read together, these signal a transition from blending (fuel composition regulation) to flex-fuel vehicle deployment (vehicle-design regulation) — a different legal architecture, with different liability allocation.
(c) Sectoral consequences
Type approval and homologation costs rise; ARAI/ICAT capacity becomes a bottleneck.
Legacy fleet. India’s in-use fleet is overwhelmingly pre-2023. A regulatory framework that advances the frontier without addressing the tail creates precisely the grievance now before the Supreme Court.
Aftermarket and retrofit. Retrofit kits for flex operation raise Section 52 MV Act alteration questions — alterations must not depart from approved specifications without prescribed sanction.
Resale and valuation. If E20-incompatibility becomes a recognised defect, pre-2023 residual values are affected — a matter of consequence in motor accident compensation, insurance valuation and assetbased lending.
Two- and three-wheelers, being the largest segment and the oldest fleet on average, carry the greatest exposure.
VI. Impact on the Agriculture Sector
(a) The transfer mechanism
The ethanol programme is, in substance, an agricultural support programme executed through the fuel supply chain. Oil marketing companies purchase ethanol at administered or negotiated prices; the differential over the fossil alternative is a transfer from the fuel consumer to the cane grower, the maize farmer, the distiller and the sugar cooperative. Government statements place additional farmer income attributable to the programme at above ₹1.66 lakh crore since 2014-15.
For a State such as Maharashtra, where cooperative sugar factories are simultaneously agricultural institutions, industrial units, political entities and — frequently — litigants, this is the single most consequential development in agricultural law in a decade.
(b) Feedstock diversion and the food-fuel question
For 2024-25 the Government allocated of the order of 52 lakh metric tonnes of surplus FCI rice and permitted diversion of about 40 lakh tonnes of sugar to ethanol; maize allocation has risen sharply, and maize has emerged as a leading feedstock. Sugar exports have been restricted. Cropping patterns are shifting from pulses and oilseeds — crops in which India is import-dependent — toward cane and maize, drawn by assured offtake.
The legal question this raises is one of priority ordering. The Essential Commodities Act, 1955 and the Sugar (Control) Order, 1966 empower the Centre to regulate supply and distribution of essential commodities in the interest of maintaining or increasing supplies and securing equitable distribution and availability at fair prices. Directing food grain into fuel is an exercise of that power in a direction the statute did not contemplate in 1955. There is no statutory food-security override — no provision that says, in terms, that in a declared shortage year feedstock diversion stands suspended. There should be.
(c) Contractual architecture
Long-Term Offtake Agreements between OMCs and dedicated ethanol plants, interest-subvention-backed project finance, and tripartite arrangements involving cooperative factories generate a substantial body of commercial litigation: price revision disputes, force majeure on monsoon failure, arbitration under Section 11 of the Arbitration and Conciliation Act, 1996, and cooperative-law disputes under the Maharashtra Cooperative Societies Act, 1960. Practitioners should expect growth here.
VII. Comparative Survey: Biofuel Law Across Jurisdictions
Article content
The comparative lesson for India. Every mature jurisdiction has moved from volumetric mandates to carbon-intensity obligations discharged through tradable instruments — RINs, CBIOs, RTFCs, CFR credits. India alone among major biofuel economies runs a pure volumetric mandate with administered prices, no tradable compliance instrument, no lifecycle certification, and — critically — no statute. Brazil legislates by federal law; the United States by the Clean Air Act; the EU by directive requiring national transposition. India regulates by executive policy.
VIII. The Law Governing Biofuels in India
(a) The constitutional foundation
List I (Union): Entry 52 (industries declared by Parliament to be in the public interest to be controlled by the Union); Entry 53 (regulation and development of oilfields and mineral oil resources; petroleum and petroleum products); Entry 84 (duties of excise on petroleum crude, high speed diesel, motor spirit, natural gas and aviation turbine fuel).
List II (State): Entry 8 (intoxicating liquors — production, manufacture, possession, transport, purchase and sale); Entry 14 (agriculture); Entry 18 (land); Entry 51 (duties of excise on alcoholic liquors for human consumption); Entry 54 (taxes on sale of petroleum crude, HSD, motor spirit, natural gas, ATF and alcoholic liquor for human consumption).
List III (Concurrent): Entry 33 (trade and commerce in, and the production, supply and distribution of, the products of any industry the control of which by the Union is declared expedient in the public interest, and of foodstuffs and edible oils).
Article 279A(5): petroleum crude, HSD, motor spirit, natural gas and ATF remain outside GST until the Council recommends otherwise. Ethanol supplied for EBP attracts GST at 5%. The result is a fuel whose components are taxed under two entirely different constitutional regimes.
(b) Lalta Prasad Vaish — the decision that changed the field
In State of Uttar Pradesh v. M/s Lalta Prasad Vaish and Sons, 2024 INSC 812 (23 October 2024), a nine- Judge Constitution Bench held, by 8:1 (Nagarathna, J. dissenting), that “intoxicating liquor” in Entry 8 of List II is not confined to potable alcohol but extends to industrial alcohol, including rectified and denatured spirit, and that Parliament lacks competence, through Entry 52 List I read with the Industries (Development and Regulation) Act, 1951, to occupy that field to the exclusion of the States. Synthetics and Chemicals Ltd. v. State of U.P., (1990) 1 SCC 109 stands overruled.
The consequence for the biofuel programme is direct and, in this author’s respectful view, underappreciated. Fuel ethanol is denatured spirit produced by fermentation. After Lalta Prasad Vaish, the States hold regulatory and taxing competence over its production, manufacture, supply, pricing and movement. A national blending mandate operated by Union executive policy is therefore dependent, at every stage of the supply chain, on the forbearance of thirty-odd State excise administrations. Several States have already altered their denatured-ethanol regimes, prompting the Centre to request — it can do no more — rationalisation of excise levies and duties on inter-State ethanol movement.
This is a structural fault line. A Union programme of national importance rests on a legislative competence the Supreme Court has held to belong to the States.
(c) The policy and statutory instruments presently in force
Policy (non-statutory):
National Policy on Biofuels, 2018 (notified by MoP&NG on 4 June 2018, superseding the MNRE policy of 2009), as amended in June 2022 — advancing the E20 target to ESY 2025-26, widening feedstock eligibility, permitting production in SEZs/EOUs, expanding the National Biofuel Coordination Committee, and permitting export in specified cases.
Roadmap for Ethanol Blending in India 2020-25 (NITI Aayog/MoP&NG Expert Committee).
Ethanol Interest Subvention Schemes; Long Term Offtake Agreements; SATAT (2018) for CBG.
Compressed Bio-Gas Blending Obligation: mandatory from FY 2025-26 at 1%, rising to 3% (2026-27), 4% (2027-28) and 5% from 2028-29, monitored by a Central Repository Body.
SAF: indicative blending of 1% (2027), 2% (2028) and 5% (2030), initially for international flights; an April 2026 decision permitting up to 1% ethanol in ATF through the alcohol-to-jet pathway certified to ASTM D7566, with a Civil Aviation Sustainability Cell established.
Biodiesel: an indicative 5% target by 2030, against actual blending well below 1%, governed by 2019 guidelines for sale of biodiesel for blending — guidelines, not rules.
Statutes and subordinate legislation actually engaged:
Article content
(d) The central defect
India has no biofuel statute. The National Policy on Biofuels, 2018 is an executive instrument issued under the Allocation of Business Rules. It creates no rights, imposes no penalties, confers no adjudicatory jurisdiction, and provides no remedy. The blending obligation binds oil marketing companies as a matter of administrative direction to public sector undertakings — not as law binding on all suppliers equally. The National Biofuel Coordination Committee is an inter-ministerial body with no statutory existence, yet it determines feedstock eligibility, blending obligations and, in effect, the composition of the fuel every citizen is compelled to buy.
A programme that reallocates several lakh crore rupees, alters the national cropping pattern, and changes the fuel in every vehicle in the country ought not to rest on a policy document.
IX. Amendments Required: A Reform Agenda
- A Biofuels (Promotion, Regulation and Sustainability) Act
Parliament should enact a consolidated statute providing for:
Definitions covering ethanol, biodiesel, HVO, CBG/biomethane, SAF, bio-methanol and RFNBOs — future-proofed by a schedule amendable by notification.
Statutory blending obligations binding on all suppliers, public and private, with penalties for default and a compliance-year architecture.
A statutory National Biofuel Authority (or statutory footing for the NBCC), with defined composition, published reasons, consultation obligations, and appellate recourse — presently absent.
Delegation limits, so that feedstock eligibility and blend levels are set within statutory bands (the Brazilian model, where the CNPE sets blends within a legislated E27-E35 and B13-B25 range, is instructive).
- Resolve the Lalta Prasad Vaish competence problem
Post-Lalta Prasad Vaish, the cleanest route is a Union law under Entry 33(a), List III dealing with trade, commerce, production, supply and distribution of fuel ethanol as a product of a scheduled industry, with Presidential assent under Article 254(2) where State legislation conflicts. Such a law should:
Define “fuel-grade denatured ethanol” as a distinct regulated commodity, separated in law from potable and industrial alcohol;
Guarantee free inter-State movement (Article 301) subject only to non-discriminatory compensatory levies, with Article 304(b) safeguards;
Provide a mechanism for compensating States for foregone excise revenue — otherwise the reform will not survive the Rajya Sabha or the Article 301 challenge that will follow.
Absent this, the programme’s escalation to E30, E85 and E100 is legally precarious.
- Consumer protection: disclosure, choice and compatibility
This author submits that the following are constitutionally required, and that the pending Goswami petition is correctly framed:
Mandatory declaration of ethanol content on the dispensing unit and on every invoice — amend the Legal Metrology Act, 2009 rules and the Petroleum Rules, 2002.
A published vehicle-wise compatibility database, maintained by MoRTH and updated by manufacturers under statutory obligation.
A statutory transition period during which E10 or E5 remains available at a prescribed minimum proportion of outlets in each district, until the pre-2023 fleet falls below a defined threshold. Sunset by data, not by decree.
Statutory bar on warranty and insurance repudiation grounded solely on use of a fuel blend that the State has mandated — by amendment to the Consumer Protection Act, 2019 and by IRDAI direction under Section 34 of the Insurance Act, 1938. This single reform would dispose of the bulk of the grievance now driving the litigation.
- A statutory sustainability and carbon-intensity regime
Mandatory lifecycle GHG thresholds for eligibility, on the RED III model (70%/80% saving), with accredited third-party certification and mass-balance chain of custody.
Water-stress-linked feedstock and siting rules: no new grain or cane-based distillery capacity in blocks classified over-exploited or critical by the CGWB, save with compensatory recharge obligations — enforceable through the Environment (Protection) Act, 1986 and CGWA notification.
Statutory food-security override: a provision suspending or reducing feedstock diversion automatically upon declared shortfall in production or a defined rise in the food price index. China’s retreat from national E10 on grain-security grounds is the cautionary precedent.
Integration with the Carbon Credit Trading Scheme under the Energy Conservation (Amendment) Act, 2022, creating a RenovaBio-style tradable decarbonisation credit. This converts a blunt volumetric mandate into an efficient carbon-intensity market and, incidentally, rewards 2G and waste-based pathways over water-intensive 1G routes. - Environmental enforcement
Statutory zero-liquid-discharge obligation for molasses-based distilleries, with graded penalties and an environmental-compensation formula, rather than case-by-case NGT quantification.
Mandatory continuous effluent and emission monitoring with public disclosure.
Regulation of aldehyde emissions in the CMVR emission schedules ahead of E85/E100 deployment. - Biodiesel, CBG and SAF: elevate guidelines to rules
A statutory biodiesel blending obligation — the 5% target has remained aspirational for a decade because it is enforced by guidelines, not by rules — coupled with a regulated UCO collectio framework building on RUCO, with traceability to prevent fraudulent feedstock declaration (a problem the EU has faced acutely).
The CBG Blending Obligation requires a statutory basis and a defined enforcement authority; a Central Repository Body created by administrative order cannot impose consequences for default.
The SAF mandate must be located in subordinate legislation under the Bharatiya Vayuyan Adhiniyam, 2024, aligned with CORSIA obligations from 2027, with certification, offtake and cost pass-through expressly provided for. - Fiscal transparency
The Petroleum Planning and Analysis Cell publishes a consolidated retail price build-up for “petrol” without a separate build-up for E20. There is no published disclosure of the ethanol procurement component, the blending cost, or the tax incidence on each component of a litre of E20. Statutory disclosure of the E20 price build-up — crude FOB, refining and OMC margin, ethanol procurement inclusive of GST and freight, central excise, State VAT, dealer commission — should be mandated. Where the citizen is compelled to buy a composite product, he is entitled to know its composition and its cost. - Agricultural and cooperative law
A model long-term offtake and contract-farming framework for feedstock, with statutory dispute resolution — a gap left open since the repeal of the 2020 farm laws. Amendments to State cooperative legislation governing the conversion of cooperative sugar factories into ethanol enterprises, the treatment of members’ cane dues against ethanol revenue, and the priority of FRP payments over ethanol working capital.
X. The Economics: Biofuels Against All Other Fuels
(a) The headline claims
Government figures place cumulative benefits since 2014-15 at foreign exchange savings above ₹1.97 lakh crore, crude import substitution of roughly 316 lakh tonnes, CO₂ avoidance of about 952 lakh tonnes, and additional farmer income exceeding ₹1.66 lakh crore. Blending rose from about 1.53% in 2013-14 to 20% in ESY 2025-26. Ethanol procurement rose from 38 crore litres in ESY 2013-14 to roughly 1,033 crore litres in ESY 2024-25. Distillation capacity expanded from about 421 crore litres in 2014 to about 2,000 crore litres in 2026.
(b) The cost side
Article content
Against a refinery-gate cost of petrol materially below these figures, ethanol is presently the more expensive component of the blend on a per-litre basis, before adjusting for its ~28 per cent lower calorific value. Adjusted for energy content, the gap widens substantially.
(c) The full economic cost
CEEW’s analysis of the “true cost” of ethanol — incorporating input subsidies, foregone alternative uses and public expenditure, not merely the procurement price — puts rice-based ethanol at approximately ₹126 per litre against an OMC procurement price near ₹60, maize at about ₹95, sugarcane juice at about ₹85.5 and B-heavy molasses at about ₹71.7. On total cost of ownership for four-wheelers, the same analysis finds petrol between 2 and 14 per cent cheaper than flex-fuel E100 at retail prices, and roughly 15 per cent cheaper at OMC procurement prices.
(d) Comparative fuel economics
Article content
(e) The honest assessment
The ethanol programme is best understood not as a cheaper fuel but as a transfer programme with energy-security and rural-income objectives, financed by fuel consumers rather than by the Consolidated Fund. Because ethanol is blended into a uniformly priced product, the subsidy is invisible: the consumer pays the same price for a litre of lower-energy fuel and absorbs the efficiency loss. There is no appropriation, no budget line, and therefore no parliamentary scrutiny of the quantum.
That is a legitimate policy choice. It is also a choice with a constitutional dimension. A levy imposed on consumers to fund a sectoral transfer, effected by executive policy rather than by law, and without disclosure of its quantum, sits uneasily with Article 265 in substance if not in form, and squarely within the reasoning that has developed around fiscal transparency and the citizen’s right to know. At minimum, it strengthens the case for the statutory disclosure recommended in Part IX.
The counter-arguments deserve equal weight: import dependence of about 88.5 per cent for crude is a strategic vulnerability that price comparisons do not capture; the programme has cleared distress in the sugar sector and reduced cane arrears; octane enhancement has value; and criticism of ethanol’s water footprint often applies with equal or greater force to the food crops the same water would otherwise irrigate. Reasonable people differ on the net balance. The argument this article advances is narrower and, I hope, less contestable: whatever the balance, it should be struck by Parliament in a statute, with disclosure, safeguards and remedies — not by executive notification.
XI. Practice Notes: Where the Litigation Will Come From
For practitioners, the following are live or imminent:
- Consumer Commission claims for engine damage and warranty repudiation in pre-2023 vehicles; product liability under Chapter VI, CPA 2019.
- Insurance repudiation disputes — Ombudsman and Commission fora.
- Writ petitions on disclosure, labelling and compatibility (the surviving framing after September 2025).
- NGT proceedings against distilleries and cooperative sugar factories for effluent discharge — polluter pays, environmental compensation.
- Excise and taxation disputes between distillers and State excise authorities in the aftermath of Lalta Prasad Vaish, including refund and restitution claims for levies collected under the overruled Synthetics and Chemicals position.
- GST disputes: inverted duty structure and input tax credit for distillers; classification of denatured versus rectified spirit.
- Commercial arbitration under long-term offtake agreements — price revision, force majeure on monsoon failure, capacity shortfall.
- Cooperative society litigation in Maharashtra: cane arrears versus ethanol revenue priority, member rights, and the conversion of sugar cooperatives into ethanol enterprises.
- Environmental clearance challenges to distillery expansion in water-stressed blocks.
XII. Conclusion
Rudolf Diesel is said to have anticipated that vegetable oils would in time become as important as petroleum. On the technical prediction he has been substantially vindicated. On the legal architecture, the world is still improvising.
India has executed the fastest large-scale biofuel transition in the world and has done it, remarkably, without a statute. That is an administrative achievement and a legal vulnerability. The programme now determines the composition of the fuel in every vehicle in the country, redirects several lakh crore rupees, reshapes the cropping pattern, and draws on aquifers already classified as over-exploited — all under an executive policy that confers no right, imposes no penalty and provides no remedy, and in a field over which the Supreme Court has recently confirmed that legislative competence lies substantially with the States.
The reform this author urges is not a retreat from biofuels. It is their translation from policy into law: a consolidated statute, a resolved federal competence, enforceable sustainability criteria, a tradable carbonintensity instrument in place of a blunt volumetric mandate, statutory consumer disclosure and choice, protection against warranty and insurance repudiation for a fuel the State compels, and honest publication of what the programme costs and who pays.
On World Biofuel Day the appropriate tribute to Diesel’s experiment is not another target. It is a Bill.
