  • India’ new climate targets are modest but significant

    Why in the News?

    India officially approved its third Nationally Determined Contribution (NDC 3.0) for the 2031-2035 period. This comes at a time when global climate leadership is weakening, especially with the US stepping back from clean energy financing and multilateral commitments. This is significant because India, despite being the third-largest emitter, is signalling continuity in climate commitment while many developed countries are retreating.

    What are the exact targets under India’s NDC-3?

    1. Emissions Intensity Reduction: Ensures 47% reduction by 2035 (from 2005 levels); builds on 45% target for 2030 and 36% already achieved by 2020.
    2. Non-Fossil Electricity Capacity: Ensures 60% installed capacity from non-fossil sources by 2035; compared to 40% (Paris target) and ~52% achieved by Feb 2026.
    3. Carbon Sink Expansion: Ensures 3.5-4 billion tonnes CO₂ equivalent sink, up from 2.5-3 billion tonnes target; 2.3 billion tonnes already created by 2021.

    What were India’s early achievements under previous NDCs?

    1. Early Target Achievement: Ensures fulfillment of 33-35% emissions intensity reduction (2005–2030 target) by 2020 itself, achieving a 36% reduction, i.e., 11 years ahead of schedule, demonstrating policy credibility and implementation capacity.
    2. Renewable Energy Transition: Ensures achievement of 40% non-fossil fuel-based installed electricity capacity well before the 2030 deadline (achieved ~2021-22), reflecting accelerated deployment of solar, wind, and other clean energy sources.
    3. Enhanced Ambition: Strengthens climate commitment by revising emissions intensity reduction target from 45% (2030) to 47% (2035), building on early success and improved capacity.
    4. Carbon Sink Creation: Ensures creation of 2.29 billion tonnes of CO₂ equivalent carbon sink by 2021, progressing steadily towards the earlier target of 2.5-3 billion tonnes, through afforestation and ecosystem restoration initiatives.
    5. Afforestation and Livelihood Linkage: Supports rural livelihoods alongside climate mitigation through forest expansion, integrating environmental sustainability with socio-economic development.
    6. Global Recognition: Secures international validation, with the Food and Agriculture Organization (FAO) ranking India 3rd globally in net gain in forest area and 9th in total forest area, highlighting effectiveness of conservation policies. 

    Why are the targets termed ‘modest’ despite progress?

    1. Marginal Increase: Expands clean energy share from 52% to only 60% by 2035, indicating slow incrementalism.
    2. Under-commitment Strategy: Avoids overpromising due to uncertainty in finance and technology access.
    3. Comparison with Capability: Existing trajectory suggests India could achieve higher targets without formal commitment.
    4. Deliberate Caution: Prevents binding commitments that may constrain future policy flexibility

    How has India overachieved its previous climate commitments?

    1. Early Emissions Reduction: Achieved 36% reduction by 2020, exceeding 33-35% target for 2030.
    2. Renewable Expansion: Rapid increase in solar and wind capacity pushed non-fossil share to ~52% by 2026.
    3. Carbon Sink Creation: Achieved 2.3 billion tonnes CO₂ sink by 2021, nearing earlier commitments.
    4. Policy Continuity: Maintains stable climate trajectory unlike abrupt reversals in other economies.

    What global developments are shaping India’s cautious climate stance?

    1. US Retreat: Weakens global leadership in renewables and climate finance.
    2. Geopolitical Conflicts: Russia-Ukraine war triggered energy insecurity, increasing fossil fuel reliance globally.
    3. Supply Chain Disruptions: Pandemic exposed vulnerabilities in global manufacturing and logistics.
    4. Energy Nationalism: Countries prioritizing domestic fossil fuel security over climate commitments.

    Why is climate finance the central constraint in India’s climate ambition?

    1. Finance Gap: Developed countries promised $300 billion/year post-2035, while developing nations demand $1.3 trillion/year.
    2. Implementation Barrier: Limits renewable expansion, storage infrastructure, and grid modernization.
    3. Equity Principle (CBDR): Requires developed nations to bear greater responsibility.
    4. Negotiation Deadlock: Failure at Baku COP29 to finalize adequate financing framework.

    How does India use climate commitments as a strategic negotiation tool?

    1. Conditional Ambition: Links higher targets to availability of finance and technology.
    2. Diplomatic Leverage: Uses moderated commitments to push for fair global burden-sharing.
    3. South Leadership: Positions itself as the voice of developing countries.
    4. Forum Engagement: Raises concerns consistently in international platforms and negotiations.

    What are the risks associated with India’s current climate strategy?

    1. Low Ambition Risk: May not align with the 1.5°C warming pathway.
    2. Fossil Lock-in: Continued reliance due to industrial growth and energy demand.
    3. Climate Vulnerability: India remains highly exposed to climate impacts despite mitigation efforts.
    4. Global Trust Deficit: Weak multilateralism reduces effectiveness of cooperative climate action.

    How is India balancing development and climate responsibility?

    1. Development Priority: Ensures energy access and economic growth remain central.
    2. Gradual Transition: Avoids abrupt fossil fuel phase-out.
    3. Domestic Financing Shift: Increasing reliance on internal resources due to global finance gaps.
    4. Adaptation Focus: Expected emphasis in COP30 (Brazil) on resilience and adaptation strategies. 

    Conclusion

    India’s NDC-3 reflects a calibrated realism shaped by global uncertainty and domestic priorities. Sustained credibility through overachievement strengthens India’s position, but enhanced ambition depends on resolving finance and technology constraints.

  • What is mineral water and how does it naturally contain dissolved minerals?

    Why in the News?

    There is a growing misconception around mineral water versus treated tap water. The issue has gained attention due to rising dependence on bottled water driven by distrust in public water supply systems, despite the fact that mineral content varies widely and is not always superior. It marks a sharp contrast between natural mineral acquisition over centuries versus artificial purification processes, raising concerns about over-commercialisation of water, regulatory gaps, and public misconceptions.

    How does mineral water naturally acquire dissolved minerals?

    1. Geological Interaction: Ensures dissolution of minerals like calcium, magnesium, and silica as water percolates through rocks such as limestone, granite, and basalt.
    2. Pressure Mechanism: Facilitates upward movement of mineral-rich groundwater due to underground pressure.
    3. Time Factor: Supports mineral enrichment over decades or centuries, unlike artificially treated water.
    4. Natural Reservoirs: Includes aquifers and springs protected from contamination.

    How is mineral water fundamentally different from tap water?

    1. Source Variation: Ensures mineral water originates from protected underground sources, while tap water is sourced from rivers and borewells.
    2. Treatment Process: Supports minimal processing for mineral water versus extensive filtration and chlorination for tap water
    3. Chemical Composition: Maintains stable mineral content in mineral water; tap water composition varies regionally
    4. Residual Chlorine: Introduces disinfectants in tap water, absent in natural mineral water.

    How is mineral water packaged and regulated in India and globally?

    1. Regulatory Bodies: Includes Food and Drug Administration, European Parliament, and Food Safety and Standards Authority of India.
      1. In the US and EU, the BIS standard 13428 required water TDS and relative proportions of various minerals to be stable over time and across producer batches.
      2. Producers are also prohibited from treating the water to change its mineral composition, and instead are only allowed to filter or decant it, aerate it and sterilise it. 
      3. Chemical decontamination, such as by adding chlorine, is also disallowed.
    2. Mandatory certification in India: Unlike many food products in India, mineral water requires Mandatory certification.
      1. To sell mineral water, producers must have both an FSSAI license and a BIS certificate and every bottle must carry the isi mark (acc to IS 13428)
      2. Labeling Norms: The FSSAI also requires the bottle to be labelled with the location and the name of the source and level of various minerals, and disallows the packager from claiming the water has any medicinal or healing properties.

    How is mineral water packaged?

    1. Source-based Bottling: Ensures mineral water is bottled directly at or near the natural source, preventing contamination and preserving its original mineral composition.
    2. Particulate Removal: Facilitates removal of physical impurities (e.g., sediments) without altering the natural mineral content.
    3. Non-chemical Disinfection: Uses ultraviolet (UV) light treatment to eliminate pathogens while maintaining chemical integrity of water.
    4. Controlled Storage: Stores water in tanks before packaging under hygienic conditions to maintain purity.
    5. Packaging Materials: Utilises glass bottles, PET bottles, and aluminium cans for storage and transport.
    6. Chemical Inertness (Glass): Ensures no reaction with water, maintaining original composition.
    7. Plastic Interaction (PET): Allows minor leaching over time, especially under heat or prolonged storage.
    8. Sealed Packaging: Ensures tamper-proof containers to avoid post-treatment contamination during distribution. 

    What are the effects of dissolved minerals on human health and water quality?

    1. Calcium & Magnesium: Strengthens bone health; increases water hardness (e.g., scaling in kettles).
      1. High calcium levels render a smooth or slightly chalky sensation while magnesium introduces a subtle bitterness
    2. Bicarbonates: Neutralises acidity; improves taste profile (gives water an almost sweet finish).
    3. Sulphates & Sodium: Sulphates are associated with magnesium rich spring and add a slightly crisp taste and sodium imparts a faint saline note.
    4. TDS (Total Dissolved Solids): Determines water interaction with environment and human body; varies from 500-2000 mg/L in India.
    5. Digestive Impact: Supports digestion through bicarbonates.

    What are the other types of water?

    1. Packaged Drinking Water: Refers to water sourced from surface or groundwater, treated using reverse osmosis, distillation, or deionisation, and may undergo remineralisation before packaging.
    2. Tap Water (Municipal Water): Refers to water supplied through public systems, sourced from rivers, lakes, or borewells, and treated through filtration and chlorination, including double chlorination in some regions to ensure microbial safety.
    3. Distilled/Demineralised Water: Refers to water from which all dissolved minerals are removed, making it unsuitable for regular consumption and mainly used for industrial purposes.
    4. Deionised Water (Industrial Water): Refers to water treated using ion exchange processes to remove calcium, magnesium, and other ions, commonly used in industrial and laboratory applications
    5. Hard Water: Refers to water with high concentrations of calcium and magnesium, leading to scaling in utensils and pipelines.
    6. Soft Water: Refers to water with low mineral content, typically found in high rainfall regions or non-calcareous geological areas.

    Why is distilled or demineralised water not suitable for regular consumption?

    1. Nutrient Deficiency: Removes essential minerals required for physiological functions.
    2. Chemical Reactivity: Increases potential to leach metals or contaminants from containers.
    3. Industrial Utility: Used in boilers and cooling systems rather than drinking.

    How is tap water treated in India and what challenges persist?

    1. Disinfection Practices: Ensures pathogen removal through chlorination, especially in tropical regions.
    2. Double Chlorination: Applies in some regions, increasing residual chlorine levels.
    3. Infrastructure Issues: Leads to contamination via leakages and sewage mixing
    4. Regional Variation: Hard water in Rajasthan, Gujarat; soft water in Himalayan and coastal regions.
    5. Regulatory Limits: Caps TDS at 500 mg/L (extendable to 2000 mg/L if no alternative source exists).

    What explains regional variations in water quality across India?

    1. Geological Factors: Determines mineral content based on rock type.
    2. Aquifer Characteristics: Influences hardness (chalk aquifers lead to hard water).
    3. Rainfall Patterns: High rainfall regions (Kerala, Mumbai) yield softer water.
    4. Urban Infrastructure: Affects contamination levels in cities. 

    Conclusion

    The distinction between mineral water and tap water extends beyond composition to issues of governance, equity, and scientific awareness. Ensuring safe, reliable, and affordable drinking water requires strengthening public infrastructure rather than increasing dependence on commercial alternatives.

  • How BioPharma Shakti can transform biologics with non-animal models

    Why in the News?

    The Union Budget 2026-27 launched BioPharma SHAKTI with ₹10,000 crore to build a global biologics and biosimilars hub. This marks a shift beyond generic drugs. The article highlights failures of animal models (e.g., 2006 Northwick Park trial), raising concerns in biologics research. It brings focus on New Approach Methodologies (NAMs) as part of broader technological and regulatory upgrades.

    Why are animal models increasingly considered unreliable in biologics research?

    1. Northwick Park trial (2006): Phase I trial of TGN1412, a monoclonal antibody (mAb), a lab-made protein targeting specific human antigens, caused severe adverse reactions in humans despite safe monkey testing. Shows failure of animal models in biologics.
    2. Clinical failure evidence: Semagacestat (2022) failed in 457 Alzheimer’s patients despite success in mouse models. Shows poor human translation.
    3. Human-specific action of biologics: Biologics such as mAbs act on highly specific human immune pathways. Animal systems cannot replicate this accurately.
    4. Species-specific differences: Variations in receptors and immune responses reduce predictive reliability across species.
    5. Complexity of biologics: Interactions in human biological systems are multi-layered and not reproducible in animals.
    6. Safety risks: Inadequate prediction of human response increases risk in clinical trials. 

    What are Non-Animal Methodologies (NAMs) and how do they work?

    Non-Animal Methodologies (NAMs) are innovative, human-relevant scientific tools, including computational models, cell-based systems (like organ-on-a-chip), and artificial intelligence, used to assess chemical safety, drug efficacy, or toxicity without animal testing. They work by simulating human biology at the molecular, cellular, or tissue level to provide faster, more accurate, and ethical predictive data than traditional animal studies.

    How do NAMs Work?

    1. In Vitro Systems: Using human cell cultures, organoids, or organs-on-chips (e.g., Emulate’s liver-on-a-chip) to replicate human organ function and predict toxic responses.
    2. In Silico/Computational Modeling: Utilizing computer modeling, AI, and big data to predict how a chemical will behave or interact with biological systems based on known data.
    3. In Chemico/Molecular Techniques: Investigating chemical interactions with molecules, such as DNA or proteins, to assess reactivity.
    4. “Omics” Studies: Using genomics, proteomics, and metabolomics to analyze cellular responses, focusing on molecular events rather than late-stage pathology.

    Where are NAMs being implemented?

    1. India: New Drugs and Clinical Trials Rules, 2023 enable use of non-animal data.
    2. Global trend: Regulators example in UK are encouraging shift toward human-relevant models. 

    What are Biologics?

    Biologics are complex, high-precision medicines derived from living sources, such as human, animal, or microorganism cells, rather than chemical synthesis. Used to treat diseases like cancer, autoimmune disorders, and rare genetic conditions, they are administered via injection or infusion to target specific molecular pathways. 

    Key Aspects of Biologics

    1. Composition: They are large, intricate molecules, such as proteins, antibodies, or gene therapies, making them much more complex than small-molecule chemical drugs
    2. Production: Unlike synthetic drugs, biologics are “grown” or manufactured using engineered cells in a laboratory, requiring rigorous production monitoring
    3. Administration: Because they are large, delicate molecules that would be broken down by stomach acid, they are given by injection or intravenous (IV) infusion
    4. Mechanism: They are targeted therapies, designed to interact with specific parts of the immune system or other biological pathways to treat conditions such as rheumatoid arthritis, Crohn’s disease, and psoriasis.
