Ethanol Blending: A Cleaner Move with Trade-offs in Mileage and Maintenance Introduction India has reached a significant milestone in its journey toward energy self-sufficiency and carbon reduction by implementing the nationwide rollout of E20 fuel—petrol blended with 20% ethanol. Achieving this target five years ahead of the original 2030 deadline (in 2025) is a major step forward. While this development enhances energy security, supports the agrarian economy (particularly sugarcane farmers), and reduces crude oil imports, it also raises important concerns. Vehicle owners and automotive experts are questioning the long-term implications for fuel efficiency, engine durability, and maintenance costs. Policy Background: Ethanol Blending in India Ethanol, an alcohol-based biofuel made from sugarcane, maize, or biomass, offers a cleaner-burning alternative that helps reduce both carbon emissions and fossil fuel dependency. India’s Ethanol Blended Petrol (EBP) Programme, launched in 2003, has been accelerated over the past decade. A key milestone—10% ethanol blending (E10)—was reached in 2022. In 2025, the country declared the nationwide completion of the E20 rollout, a critical move aligned with its renewable energy and energy security goals under the National Bio-Energy Programme. Environmental and Economic Benefits The E20 programme is projected to:
However, while these benefits are considerable on a macro level, the impact on individual vehicle performance and ownership costs introduces a nuanced trade-off. Fuel Efficiency Concerns One of the most debated drawbacks of ethanol blending is reduced mileage, as ethanol contains about 30% less energy per litre compared to petrol. This means vehicles consume more fuel for the same distance travelled.
Maintenance and Compatibility Risks Beyond efficiency, maintenance-related issues have surfaced due to ethanol’s hygroscopic (moisture-absorbing) properties, which can cause:
Industry experts, including those from Primus Partners and the Federation of Automobile Dealers Associations (FADA), warn that older vehicles not designed for E20 could face higher wear and tear, leading to increased service costs. Automobile Industry Response Automakers are responding to the challenge by upgrading existing models and issuing compatibility guidelines:
As a proactive step, manufacturers have begun rolling out E20-compatible models and updating service advisories for older ones. Looking Ahead: Higher Ethanol Blends With E20 fully implemented, discussions are now underway about moving to E30 or E40 blends. However, experts stress that higher ethanol content will require:
Until these measures are addressed, advancing beyond E20 could increase strain on consumers and the service ecosystem. |

India’s Fighter Jet Transition: MiG-21 Retirement and the IAF''s Modernisation Hurdles End of an Era: MiG-21 Retirement The Indian Air Force (IAF) will formally retire its MiG-21 fighter jets by September 2025, concluding a 60-year legacy. However, this move will also reduce the IAF’s combat strength to 29 squadrons, significantly below the sanctioned 42 squadrons. The delay in inducting the Light Combat Aircraft (LCA) Mk1A further exacerbates this capability gap, especially as China strengthens its aerial fleet with over 1,300 fourth-generation and two fifth-generation fighters (J-20, J-31). To maintain strategic balance, experts argue that India must induct 400–450 advanced jets over the coming decade. Legacy of the MiG-21 Originally inducted in 1963, the MiG-21 was a single-engine, single-seater multi-role fighter. India acquired over 700 units across various variants, including Type-77, Type-96, BIS, and the upgraded MiG-21 Bison. While it symbolised India’s entry into supersonic aviation, a spate of accidents—partly due to the absence of Advanced Jet Trainers—earned the aircraft the nickname "flying coffin." Since 1965, there have been nearly 500 crashes and over 450 fatalities. One notable incident occurred during the 2019 Balakot post-strike dogfight, when a MiG-21 flown by Wing Commander Abhinandan Varthaman was shot down by Pakistani jets. IAF’s Operational Shortfall With the MiG-21 and Jaguar fleets set for full retirement by 2030, the IAF risks losing about 16 squadrons, further shrinking its already under-strength force. Though future platforms like the Advanced Medium Combat Aircraft (AMCA) and the Medium Role Fighter Aircraft (MRFA) are under development, production delays and cost concerns cast uncertainty over their timelines. Currently, the IAF operates just two LCA Mk1 squadrons, while delays in the more advanced Mk1A variant continue to stall force modernisation. LCA Mk1A: Delayed Yet Critical In 2021, a $6.5 billion deal was signed for 83 LCA Mk1A aircraft (73 fighters and 10 trainers), with deliveries slated to begin in March 2024. However, none have been delivered so far.
India has also procured 272 Su-30MKIs from Russia, with only around 200 currently operational. To offset losses, the Defence Ministry signed a ₹1,300 crore deal in 2024 to procure 12 more Su-30MKIs, with HAL license-producing the engines. Path Ahead: Modernisation Through Indigenous Capability The IAF plans to induct over 600 fighter jets over the next two decades, with an emphasis on domestic manufacturing. The roadmap includes:
However, the MRFA programme, despite an RFI issued in 2019, remains stalled due to budget constraints and shifting priorities. To bridge capability gaps in the interim, India is exploring limited imports of fifth-generation aircraft, including the Russian Su-57 and American F-35. The AMCA programme—featuring Mk1 powered by GE414 engines and Mk2 with a co-developed 110KN engine—is central to India''s future air superiority. The Aeronautical Development Agency (ADA) has invited private sector participation to fast-track AMCA production, signalling a shift in India''s defence manufacturing strategy. Conclusion India’s twin transitions—toward cleaner energy through ethanol blending and toward military modernisation through indigenous fighter jet development—reflect bold policy directions. However, both journeys face significant technical, economic, and operational hurdles that must be addressed to fully realise their intended benefits. |

Supreme Court Affirms Pollution Control Boards’ Power to Levy Environmental Compensation Landmark Ruling on Environmental Governance In a significant judgment, the Supreme Court of India has ruled that Pollution Control Boards (PCBs) are legally empowered to impose environmental compensation on polluters under their statutory authority as per the Water Act (1974) and Air Act (1981). A bench comprising Justices P.S. Narasimha and Manoj Misra affirmed that PCBs can seek restitutionary or compensatory damages, either through fixed monetary payments or bank guarantees, as preventive tools to mitigate or deter environmental harm. Background of the Case The case stemmed from a legal challenge brought by the Delhi Pollution Control Committee (DPCC) against a 2012 Delhi High Court decision, which had invalidated DPCC''s notices seeking compensation and bank guarantees from property owners operating without environmental clearance. The High Court had ruled that only courts could levy such penalties. However, the Supreme Court overturned that decision, holding that the DPCC—like all PCBs—has the regulatory power to impose compensation under environmental laws. Expanded Powers under the Water and Air Acts The apex court clarified that PCBs have the authority to levy and collect compensation for the restoration of polluted ecosystems, specifically air and water bodies. This power is exercised under:
These provisions allow PCBs to demand upfront payments or financial guarantees from entities as a pre-emptive environmental safeguard. Defined Scope and Legal Limits While empowering the PCBs, the Court also placed boundaries on the scope of these powers. It emphasized that:
Additionally, the Court mandated that the compensation framework must uphold the principles of natural justice, ensuring due process before enforcement. Legal Precedents Supporting the Judgment The Supreme Court anchored its reasoning in landmark environmental jurisprudence, notably:
These cases established the restitutionary character of environmental compensation and recognised it as both a constitutional and statutory obligation, separate from punitive legal sanctions. Key Doctrinal Principles Established The ruling sets forth important legal doctrines guiding how and when PCBs can impose compensation:
Broad Regulatory Mandate and Constitutional Linkages The Court emphasized the comprehensive regulatory mandate entrusted to PCBs, which includes:
It linked these duties to the State’s constitutional responsibility under Article 51A (Fundamental Duties), particularly relevant in the context of the climate emergency. The Court highlighted that protecting air and water is central to upholding citizens'' fundamental rights. Towards Stronger Environmental Remedies The Supreme Court underscored that with the expansion of environmental rights, there must be a parallel strengthening of enforcement mechanisms. It stressed that:
