  • Why some PLI schemes are in the slow lane?

    Why in the News?

    Six out of the 14 Production-Linked Incentive (PLI) schemes, including textiles, solar modules, IT hardware, automobiles, advanced chemical cells (ACC), and speciality steel, are progressing at a relatively slower pace.

    What are the primary reasons for the slow implementation of PLI schemes?

    • Stringent Eligibility Norms: Many industries have reported that the eligibility criteria for participation in PLI schemes are too stringent, which limits the number of companies that can benefit from the incentives.
    • Initial Setup Challenges: Establishing a domestic manufacturing base from scratch is a monumental task. Industries such as solar modules and advanced chemistry cells (ACC) require substantial time—ranging from one-and-a-half to three years—to set up manufacturing operations, delaying employment generation.
    • Access to Resources: Companies face difficulties in accessing critical resources, including Chinese machinery and skilled technicians, which can hinder their ability to ramp up production quickly.
    • Market Dependency: Some sectors remain heavily reliant on imports and have not yet transitioned to a self-sufficient manufacturing model, impacting their growth under the PLI framework.
    • Slow Disbursement of Funds: The initial years of the scheme saw minimal disbursement of funds, with only a small percentage of the total incentive outlay being paid out in the first two years.

    Which sectors are experiencing the most significant slowdowns, and why?

    • Textiles: This sector is struggling due to high competition and stringent norms that have slowed down participation and growth.
    • Solar Modules: Despite being a strategic sector for renewable energy, delays in establishing manufacturing capabilities have led to slow progress.
      • As of June 2024, India’s solar module manufacturing capacity reached 77.2 GW, but the solar cell capacity was only 7.6 GW, leading to supply shortages that delayed projects.
    • Automobiles: While some companies are making progress, the automobile sector overall is hindered by initial setup challenges and fluctuating market conditions. 
      • Factors such as rising raw material costs and shifts in consumer preferences towards electric vehicles are creating a complex environment for traditional automakers.
    • Advanced Chemical Cells (ACC): Similar to solar modules, this sector faces long commissioning periods that delay employment outcomes. Because of the lengthy development timelines for manufacturing facilities and the need for substantial investment in technology are contributing to slower growth in this strategic area.
    • IT Hardware: Although recently upgraded with increased funding, it still lags behind in implementation compared to more successful sectors like mobile manufacturing.

    What measures can be taken to enhance the effectiveness of PLI schemes? (Way forward)

    • Revising Eligibility Criteria: Simplifying the eligibility requirements could encourage more companies, especially smaller firms, to participate in the schemes and benefit from incentives.
    • Increasing Support for Supply Chains: Establishing robust supply chains is crucial. The government could provide additional support to smaller suppliers who are essential for scaling up production across sectors.
    • Streamlining Resource Access: Facilitating easier access to necessary machinery and skilled labor can help companies ramp up production more effectively and reduce dependency on imports.
    • Regular Reviews and Adjustments: Continuous monitoring and adjustments based on sector performance can help identify bottlenecks early and allow for timely interventions.
    • Encouraging Ancillary Industries: Promoting the establishment of ancillary industries around larger beneficiaries could create additional jobs and enhance local manufacturing capabilities.

    Mains question for practice:

    Q Evaluate the challenges in the implementation of the Production-Linked Incentive (PLI) schemes in India. Highlight the sectors experiencing significant slowdowns and suggest measures to enhance the effectiveness of these schemes. (250 words) 15M

  • [pib] Breakthrough in Quantum Noise Research

    Why in the News?

    Researchers at the Raman Research Institute (RRI) found that quantum noise—usually seen as a problem—can sometimes help connect particles in a special way called entanglement, which is important for future quantum technologies.

    What is Quantum Noise?

    • Overview: Quantum noise refers to random disturbances that affect quantum systems, often causing loss of coherence or decoherence.
    • Traditional View: It is typically seen as harmful, especially for quantum entanglement, which is crucial for quantum computing and communication.
    • Entanglement Concept: It is a phenomenon where particles are so correlated that the state of one instantly affects the state of another, even at a distance.
    • Effect of Decoherence: Noise-induced decoherence breaks this entanglement, thereby reducing the efficiency of quantum technologies.

    Key Findings:

    • Observation: Found that quantum noise can generate or revive entanglement, contrary to its typical reputation as destructive.
    • Focus Area: Studied intraparticle entanglement, which involves internal properties (like spin and path) of a single particle.
    • Contrast with Interparticle Entanglement: Unlike interparticle entanglement (between separate particles), intraparticle entanglement showed resilience under noise.
    • Types of Noise Studied:
      • Amplitude Damping: Energy loss
      • Phase Damping: Loss of phase information
      • Depolarizing Noise: Random changes in quantum state
    • Major Observation: Under amplitude damping, intraparticle entanglement showed delayed decay, revival, and even creation from unentangled states.
    • Interparticle Comparison: In contrast, interparticle entanglement exhibited steady decay with no revival or generation.

    Scientific Implications:

    • New Perspective: Challenges the assumption that quantum noise is purely harmful, showing it can be a resource in certain contexts.
    • Technological Potential: Intraparticle entanglement is more noise-resilient, making it valuable for stable quantum devices.
    • Application Areas: Findings are relevant to quantum communication, QKD (quantum key distribution), quantum computing, and quantum sensing.
    • Predictive Advantage: The new formula allows precise prediction of entanglement behavior, aiding the design of robust systems.
    • Platform Independence: Results are platform-agnostic, applicable to photons, neutrons, trapped ions, etc.
    [UPSC 2025] Consider the following statements:

    I. It is expected that Majorana 1 chip will enable quantum computing. II. Majorana 1 chip has been introduced by Amazon Web Services (AWS). III. Deep learning is a subset of machine learning.

  • Scientists decode Locust Pheromones for Eco-Friendly Control

    Why in the News?

    Researchers in China have discovered a method to curb locust swarming by manipulating their pheromones, paving the way for eco-friendly locust control.

    What are Locust Swarms?

    • Locusts are large grasshoppers capable of forming massive swarms, consuming up to their body weight in food daily, and travelling 150 km/day with favourable winds.
    • They are highly destructive, stripping crops and threatening food security. A single swarm can consume food equivalent to the daily needs of 35,000 people.
    • In India, Locust Control and Research (LC&R) oversees locust management.
    • The Locust Warning Organisation (LWO), established in 1939, monitors and controls locust activity in states like Rajasthan, Gujarat, Punjab, and Haryana.
    • The 2019-2022 desert locust outbreak was one of the worst in decades, devastating India, Pakistan, and East Africa, destroying over 200,000 hectares of crops.
    • Despite existing control measures, locust outbreaks remain difficult to manage due to their rapid breeding capabilities.

    About Locust Pheromones:

    • Locust Behavioural Phases: Locusts exhibit two behavioural phases—solitary (non-swarming) and gregarious (swarming). The shift to gregariousness leads to swarm formation.
    • Key Pheromone – 4-Vinylanisole (4VA):
      • Identified in 2020 by Chinese researchers.
      • Released from locusts’ hind legs after feeding, especially due to the digestion of phenylalanine (a plant compound).
      • Acts as an aggregation pheromone, attracting other locusts and triggering group behaviour.
    • Biochemical Pathway:
      • Enzymes 4VPMT1 (dominant) and 4VPMT2 convert a precursor molecule (4VP) into 4VA.
      • This process is crucial in converting solitary locusts into swarm-forming gregarious ones.

    Recent Breakthrough and Its Implication:

    • Discovery: Researchers at the Chinese Academy of Sciences genetically blocked 4VPMT1, preventing locusts from producing 4VA and stopping swarm formation.
    • Limitations: 4NP is toxic and environmentally persistent, raising concerns for large-scale deployment.
    • Strategy Proposed: RNA interference (RNAi)-based biopesticides targeting 4VPMT genes to prevent 4VA production without toxicity.
    • Wider Implications:
      • Marks the first pollution-free molecular approach to locust control.
      • Can reduce reliance on synthetic pesticides, protect crops, and support sustainable agriculture.
      • Offers a precision pest control model based on insect behavioural biochemistry.
    [UPSC 2001] American multinational company, Monsanto has produced an insect-resistant cotton variety that is undergoing field- trials in India. A toxin gene from which ONE of the following bacteria has been transferred to this transgenic cotton ?

  • Smoke and Sulphur: On sulphur dioxide emissions, public health

    Why in the News?

    Recently the Environment Ministry of India has recently exempted most coal-fired power plants from installing Flue Gas Desulphurisation (FGD) systems, reversing its 2015 mandate. This move weakens efforts to control sulphur dioxide (SO₂) emissions, a harmful air pollutant.

    What is Flue Gas Desulphurisation (FGD) system? 

    Flue Gas Desulphurisation (FGD) systems are air pollution control technologies used in thermal power plants to remove sulphur dioxide (SO₂) from flue gases (the exhaust emitted when coal or oil is burned).

    Why has FGD installation been exempted for most coal plants?

    • Low Sulphur Content in Indian Coal: Indian coal contains naturally low sulphur, reducing the urgency to control SO₂ emissions. Eg: The expert committee stated that SO₂ levels near plants using Indian coal were already below permissible limits.
    • High Installation and Operational Costs: Installing FGD systems is capital-intensive and can increase electricity tariffs. Eg: Many private power producers cited cost constraints as a barrier to following the 2015 FGD mandate.
    • Limited Vendor Capacity in India: There is a shortage of FGD equipment suppliers, causing delays in implementation. Eg: From 2015–2024, only 8% of 600 units installed FGDs, primarily by NTPC (a public sector company).
    • Impact of COVID-19 Pandemic: The pandemic caused supply chain disruptions and delayed project execution timelines. Eg: The Environment Ministry cited COVID-related delays for missing 2024 FGD deadlines.
    • Scientific Reassessment of SO₂ Effects: New studies suggest sulphates formed from SO₂ may have a climate-cooling effect, weakening the urgency of emission controls. Eg: The Power Ministry argued that reducing sulphates could actually worsen global warming.

    How does SO₂ affect health and air quality?

    • Respiratory Health Impacts: Sulphur dioxide (SO₂) irritates the respiratory tract, causing issues such as asthma, bronchitis, and shortness of breath, especially among vulnerable populations like children and the elderly. In Delhi, spikes in SO₂ levels have been linked to increased hospital visits for respiratory ailments during winter months.
    • Formation of Particulate Matter (PM2.5): SO₂ reacts in the atmosphere to form sulphate aerosols, a major component of PM2.5, which penetrates deep into lungs and contributes to air pollution. Industrial belts like Singrauli in Madhya Pradesh record high levels of particulate pollution, partly due to emissions from coal-fired plants.
    • Reduced Visibility and Environmental Damage: SO₂ contributes to acid rain and haze, damaging crops, soil, and water sources, and reducing visibility. Areas near thermal power plants, such as in Chhattisgarh, have reported acidic soil degradation, affecting agriculture.

    What does selective FGD enforcement indicate about regulation?

    • Location-Based Policy Inconsistency: The decision to mandate FGD installation only near NCR and urban hotspots suggests that environmental regulations are being applied selectively, not based on uniform scientific standards, but geographical and political considerations.
    • Weak Enforcement and Shifting Priorities: Exempting most coal plants despite earlier commitments reflects regulatory dilution, raising concerns about policy backtracking and the government’s willingness to compromise on environmental health in favor of industrial or economic concerns.
    • Undermining Scientific Credibility and Public Trust: Ignoring the original mandate without robust public debate weakens trust in evidence-based regulation, indicating that scientific advisories are not consistently followed in policy implementation.

    Why is public debate vital before policy shifts on pollution?

    • Ensures Transparency and Accountability: Open public debate creates transparency, compelling policymakers to justify decisions and remain accountable to citizens.
    • Strengthens Scientific Rigor: Debate enables scientific scrutiny of environmental claims, ensuring that policy changes are based on credible evidenceand expert consultation.
    • Safeguards Public Health and Democratic Rights: Inclusive discussions protect public health and uphold democratic values by allowing citizens to voice concerns over pollution-related policies.

    Why is public debate vital before policy shifts on pollution?

    • Perform, Achieve and Trade (PAT) Scheme: Implemented by the Bureau of Energy Efficiency (BEE), this market-based mechanism promotes energy efficiency in industries, indirectly reducing emissions.
    • National Clean Air Programme (NCAP): Launched in 2019, it aims for a 20–30% reduction in PM2.5 and PM10 levels by 2024 (now extended), and addresses urban air pollution through sector-specific mitigation plans.
    • Retrofitting of Plants: Plants identified in pollution hotspots, those near NCR or million-plus cities, are required to install FGD by 2028, as per latest Environment Ministry directive.
    • Promotion of Renewable Energy and Ujjwala Yojana: Transition towards cleaner energy sources (solar, wind) and LPG distribution under Ujjwala Yojana has reduced reliance on coal and biomass, indirectly curbing SO₂ emissions.

    Way forward: 

    • Revise FGD Policy Through Transparent Public Consultation: Any change in environmental regulation, especially exemptions, must involve scientific review, public debate, and stakeholder consultations to ensure credibility and protect public health.
    • Strengthen Pollution Monitoring and Accountability: Enhance the real-time SO₂ monitoring network, enforce uniform emission standards, and link compliance with financial or operational incentives to promote cleaner technologies across all power plants.

    Mains PYQ:

    [UPSC 2024] Industrial pollution of river water is a significant environmental issue in India. Discuss the various mitigation measures to deal with this problem and also the government’s initiatives in this regard.

    Linkage: The article talks about the Environment Ministry’s decision to exempt most coal-fired plants from mandatory Flue Gas Desulphurisation (FGD) systems, which is a significant government initiative related to an environmental issue (sulphur dioxide emissions) and its mitigation. This is a direct and comprehensive question about environmental issues and the government’s initiatives and mitigation measures.

  • Assessing India’s Carbon Credit trading scheme targets 

    Why in the News?

    The Indian government recently set greenhouse gas (GHG) emissions intensity targets for key industrial sectors under its Carbon Credit Trading Scheme (CCTS). These targets apply to eight major industries, including steel, cement, aluminium, and textiles, and aim to reduce emissions per unit of production.

    What is CCTS?

    The Carbon Credit Trading Scheme (CCTS) allows entities—such as factories, refineries, or power plants—that emit less than their permitted carbon limits to earn carbon credits. These credits can then be traded with other entities that have exceeded their emission limits.

    What is the importance of assessing carbon targets at the economy-wide level?

    • Reflects true environmental impact: Evaluating targets at the economy-wide level ensures we understand the overall reduction in greenhouse gas emissions, which is the ultimate goal of climate action.
    • Enables flexible compliance: It allows efficient entities to overachieve and trade credits with less efficient ones, reducing total emissions cost-effectively. Eg: In India’s PAT scheme, cement plants exceeding targets sold energy-saving certificates to aluminium units lagging behind.
    • Aligns with national commitments: It supports the evaluation of whether India is on track to meet its Nationally Determined Contributions (NDCs) and net-zero targets, beyond fragmented sectoral views. Eg: India aims to reduce emissions intensity of GDP by 45% by 2030 – a goal only visible through economy-wide analysis.

    What is the PAT Scheme?

    The PAT Scheme sets energy efficiency targets for large, energy-intensive industries. Companies that exceed their targets earn Energy Saving Certificates (ESCerts), which they can trade with other companies that fail to meet their targets.

    How has the PAT scheme proven effective in reducing energy intensity?

    • Encouraged market-based efficiency: The Perform, Achieve and Trade (PAT) scheme allowed industries to meet energy targets using tradable efficiency certificates, creating a cost-effective compliance mechanism.
    • Achieved aggregate reduction: Despite mixed results at the entity or sector level, overall energy intensity in India declined across PAT cycles, proving its system-wide impact. Eg: Between 2012–14, even as chlor-alkali sector’s intensity rose, combined data showed less energy used per unit of output.
    • Enabled flexible transition: PAT helped industries adopt incremental improvements or buy credits instead of making costly in-house upgrades, ensuring participation without economic strain. Eg: Aluminium units improved production processes, while others chose certificate trading to meet targets.

    Why are entity-level targets insufficient to assess emission reduction?

    • Limited Scope of Impact: Targets at the entity level show progress in isolation and may miss the broader picture. For instance, even if some paper or chlor-alkali plants increase their energy use per unit of output, overall national emissions may still fall due to reductions in other sectors.
    • Focus on Transactions, Not Outcomes: These targets often guide financial trades between companies rather than ensuring actual emissions reduction. A steel plant may meet its target not by cutting emissions but by buying efficiency certificates from another unit.
    • Inconsistency Across Sectors: Emission reductions may vary widely across sectors. While cement and aluminium sectors may improve efficiency, others may lag. Solely relying on entity targets could misrepresent the real national decarbonisation progress.

    What limits the comparison of CCTS targets with past and future benchmarks?

    • Mismatch in Scope: The CCTS targets apply only to a part of India’s industrial base, making it difficult to compare them with economy-wide goals like the Nationally Determined Contributions (NDCs). Eg. CCTS covers only 8 industrial sectors, while NDCs span all sectors including agriculture and transport.
    • Changing Baselines and Ambition Levels: Past schemes like PAT Cycle I had relatively modest targets. Comparing them with current CCTS goals may underestimate the urgency for stronger action aligned with net-zero by 2070. Eg. A sector that achieved 1% reduction earlier may now require over 2.5% annual reduction to stay on track.
    • Different Indicators Used: Past targets often focused on energy intensity, while future goals (like NDCs) emphasise emissions intensity per GDP or value added, making direct comparison methodologically inconsistent. Eg. Comparing energy saved per unit of production vs emissions per unit of GDP distorts true climate ambition.

    How do CCTS targets align with India’s NDC and net-zero goals?

    • Partial Alignment with Emission Intensity Reduction: The CCTS targets aim to reduce emissions intensity in key industrial sectors, contributing to India’s NDC goal of reducing emissions intensity of GDP by 45% by 2030 (compared to 2005 levels). However, the annual reduction rateof ~1.68% in CCTS sectors is lower than the required pace for full alignment.
    • Lag Behind Power Sector Decarbonisation: Compared to the power sector, which has low-cost mitigation options and a projected 3.44% annual decline in emissions intensity, the industrial sector’s slower pace (~2.53%) under CCTS may hinder the broader net-zero pathway.
    • Need for Greater Sectoral Ambition: The current CCTS trajectory appears less aggressive than necessary for the 2070 net-zero target. Without scaling upambition across more sectors and tightening targets, CCTS alone cannot ensure full alignment with India’s long-term climate goals.

    Way forward: 

    • Enhance Sectoral Ambition with Dynamic Targeting: Revise CCTS targets periodically based on economy-wide modelling aligned with India’s NDC and net-zero goals, ensuring progressively stringent emission intensity reductions across all major industrial sectors.
    • Integrate Technology and Incentives: Promote adoption of clean technologies through financial incentives, carbon pricing, and capacity-building support to enable industries to decarbonize efficiently without compromising growth.
