  • Why carbon capture is key to achieving net-zero goal

    Why in the News?

    The Union Budget has, for the first time, made a large, dedicated fiscal commitment of ₹20,000 crore to carbon capture, utilisation and storage. This marks a shift from pilot-driven experimentation to scale-oriented deployment. The urgency is underscored by global data showing 1 billion tonnes of annual CO₂ capture required by 2030, while only 50 million tonnes are currently captured worldwide. India’s net-zero pathway increasingly depends on CCUS as emissions from cement, steel and chemicals cannot be eliminated through renewable energy substitution alone.

    What is Carbon Capture, Utilisation and Storage?

    1. It refers to technologies that capture CO₂ from industrial processes, transport it, and either store it in geological formations or convert it into useful products.
    2. Process Stages: CCUS involves capturing carbon dioxide (via post-combustion, pre-combustion, or oxy-fuel combustion), transporting it, and either using it for industrial applications or storing it permanently
    3. Role in Climate Change: It is essential for decarbonizing “hard-to-abate” sectors, including steel, cement, and chemical production, which account for significant global emissions.
    4. Carbon Removal: CCUS enables negative emissions through technologies like Bioenergy with Carbon Capture and Storage (BECCS) and Direct Air Capture (DACCS).
    5. Challenges: High capital costs, energy intensity (high auxiliary power consumption), safety concerns, and infrastructure needs for transport are major bottlenecks.

    What Does Carbon Capture, Utilisation and Storage Involve?

    1. Carbon Capture: Enables separation of CO₂ from industrial exhaust streams in cement, steel, power and refining operations.
    2. Carbon Storage: Facilitates long-term containment of CO₂ in geological formations such as depleted oil and gas reservoirs.
    3. Carbon Utilisation: Supports conversion of captured CO₂ into chemicals and industrial inputs, reducing fresh fossil use.

    Why Is CCUS Critical for Achieving Net-Zero?

    1. Hard-to-Abate Emissions: Addresses emissions that arise from chemical reactions in cement and steel, not from fuel combustion.
    2. Limits of Renewables: Recognises that shifting to renewable electricity does not eliminate process emissions in heavy industry.
    3. Climate Mitigation: Enables deep emissions reduction without compromising industrial output and economic growth.

    What Is the Current Global Status of Carbon Capture?

    1. Operational Capacity: Includes 45 commercial CCUS facilities worldwide.
    2. Captured Volume: Accounts for only 50 million tonnes of CO₂ annually, far below climate targets.
    3. 2030 Requirement: Indicates a need for 1 billion tonnes of CO₂ capture per year by 2030 to align with net-zero pathways.
    4. Deployment Gap: Highlights a sharp mismatch between climate targets and present technological scale.

    What Is the Status of CCUS Technologies in India?

    1. Pilot Projects: Includes initiatives by Tata Steel, Dalmia Cement, NTPC, ONGC, focusing on capture feasibility.
    2. Research Ecosystem: Involves dozens of research groups working on capture materials and processes.
    3. Institutional Leadership: Anchored by Centres of Excellence at Indian Institute of Technology Bombay and Jawaharlal Nehru Centre for Advanced Scientific Research, focusing on indigenous CCUS solutions.
    4. Readiness Gap: Indicates laboratory-level maturity but limited field-scale testing.

    How Does the Union Budget Change the CCUS Landscape?

    1. Fiscal Allocation: Provides ₹20,000 crore for CCUS technology development and deployment.
    2. Scale Transition: Signals movement from pilot projects to industrial demonstration.
    3. Cost Reduction: Aims to address high capital and operational costs that restrict commercial viability.
    4. Industrial Adoption: Targets steel, cement, refineries and chemicals as early adopters.

    Why Are Certain Industries Central to CCUS Deployment?

    1. Cement Sector: Generates CO₂ as an inherent by-product of limestone calcination.
    2. Steel Sector: Emits carbon through coke-based reduction processes.
    3. Chemical and Refining Industries: Produce process emissions independent of energy source.
    4. Competitiveness: Aligns emission reduction with global trade requirements, including carbon border measures.

    What Are the Economic and Strategic Benefits of CCUS?

    1. Industrial Continuity: Enables emission reduction without relocating or shutting down core industries.
    2. Global Competitiveness: Reduces exposure to mechanisms such as the EU’s Carbon Border Adjustment Mechanism.
    3. Technology Leadership: Positions India as a developer, not just adopter, of CCUS technologies.
    4. Cost Containment: Prevents loss of competitiveness from carbon-intensive exports.

    Conclusion

    CCUS is not a substitute for renewable energy but a necessary complement for India’s net-zero strategy. The Budget’s ₹20,000 crore allocation marks a decisive shift from experimentation to scale. However, success depends on rapid field deployment, cost reduction, and industry integration to ensure CCUS delivers measurable emissions reduction by 2030.

  • Wetlands as a National Public Good

    Why in the News?

    India marked World Wetlands Day under the theme “Wetlands and Traditional Knowledge”, and on the occasion added two new Ramsar sitesPatna Bird Sanctuary in Uttar Pradesh and Chhari-Dhand in Gujarat—taking the country’s total Ramsar sites to 98.

    What are Wetlands?

    Wetlands are areas of land saturated with water either permanently or seasonally. They include lakes, ponds, marshes, floodplains, mangroves, lagoons, peatlands and man made systems like tanks and kulams.

    Key Facts and Significance

    • India has lost nearly 40 percent of its wetlands in the last three decades
    • Around 50 percent of remaining wetlands show ecological degradation
    • Wetlands act as natural flood buffers, groundwater recharge zones and water purifiers
    • They support biodiversity, fisheries, agriculture and local livelihoods
    • Coastal wetlands like mangroves reduce cyclone and storm surge impacts

    Policy and Institutional Framework

    • Wetlands Conservation and Management Rules, 2017 provide legal framework for identification, notification and protection
    • National Plan for Conservation of Aquatic Ecosystems focuses on planning, monitoring and outcome based restoration
    • Coastal Regulation Zone framework protects coastal wetlands
    • Ramsar designation under the Ramsar Convention gives global recognition and conservation responsibility
    • India has 98 Ramsar sites, highest in South Asia
    [2022] If rainforests and tropical forests are the lungs of the Earth, then surely wetlands function as its kidneys.” Which one of the following functions of wetlands best reflects the above statement? (a) The water cycle in wetlands involves surface runoff, subsoil percolation and evaporation. 

    (b) Algae form the nutrient base upon which fish, crustaceans, molluscs, birds, reptiles and mammals thrive. 

    (c) Wetlands play a vital role in maintaining sedimentation balance and soil stabilisation. 

    (d) Aquatic plants absorb heavy metals and excess nutrients.

  • [3rd February 2026] The Hindu OpeD: Wetlands as a national public good

    PYQ Relevance

    [UPSC 2023] Comment on the National Wetland Conservation Programme initiated by the Government of India and name a few India’s wetlands of international importance included in the Ramsar Sites. 

    Linkage: The question links environmental governance with ecosystem conservation, focusing on policy design, implementation gaps, and international commitments under the Ramsar Convention. It allows integration of wetlands’ role in climate resilience, disaster risk reduction, and sustainable development using current NPCA/NWCP reforms.

    Mentor’s Comment

    Wetlands are among India’s most degraded ecological assets despite being critical for water security, flood control, climate resilience, and livelihoods. This topic is important because it brings together environmental governance, federalism, disaster management, and sustainable development, making it highly relevant for GS III.

    The article is valuable for aspirants as it goes beyond laws and schemes and highlights why implementation has failed, fragmented institutions, project-based restoration, and neglect of hydrological systems. It introduces the idea of wetlands as national public goods, a strong analytical frame that can be used in mains answers to show conceptual clarity.

    Why in the News

    World Wetlands Day 2026 renews global attention on wetlands, coinciding with India’s worsening degradation record. Nearly 40% of India’s wetlands have vanished in three decades, and 50% of remaining wetlands show ecological degradation. This marks a sharp contrast with traditional community-managed systems that sustained wetlands for centuries. Despite the presence of regulatory frameworks like the Wetlands (Conservation and Management) Rules, 2017, degradation continues due to fragmented implementation, project-based restoration, and weak governance. 

    Why are wetlands ecologically and economically critical?

    1. Hydrological regulation: Supports groundwater recharge, flood buffering, and sediment control through natural flow regimes.
    2. Livelihood security: Sustains fishing, grazing, agriculture, and cultural practices across rural and peri-urban landscapes.
    3. Climate resilience: Absorbs cyclonic impacts, sea-level rise, and extreme rainfall, especially in coastal zones.
    4. Biodiversity conservation: Maintains habitats for migratory birds, aquatic species, and riparian ecosystems.

    What has driven large-scale wetland degradation in India?

    1. Land-use conversion: Replaces natural wetlands with real estate, roads, and networks, permanently altering hydrology.
    2. Encroachment pressures: Intensifies in highly populated regions due to weak land demarcation and enforcement.
    3. Hydrological disruption: Dams, embankments, canals, mining, and sand extraction block or divert natural flows.
    4. Pollution loading: Converts wetlands into sewage sinks through untreated wastewater and industrial effluents.
    5. Groundwater over-extraction: Reduces inflows, accelerates drying, and collapses ecological function.

    Why are existing policy frameworks insufficient?

    1. Fragmented governance: Distributes responsibility across departments without integrated watershed planning.
    2. Weak implementation: Lacks consistent, high-quality execution despite the presence of legal frameworks.
    3. Project-centric approach: Focuses on beautification rather than ecological functionality.
    4. Data gaps: Suffers from outdated or inaccurate cadastral maps and incomplete inventories.
    5. Limited enforcement: Fails to prevent degradation despite notification and regulatory provisions.

    How effective are current regulatory instruments?

    1. Wetlands (Conservation and Management) Rules, 2017: Provides a legal framework but lacks implementation consistency.
    2. National Plan for Conservation of Aquatic Ecosystems (NPCA): Shifts focus to structured planning and outcome-based management but requires stronger monitoring.
    3. Coastal Regulation Zone (CRZ): Aims to preserve coastal ecological integrity but faces infrastructure-driven dilution.
    4. Ramsar designation: Recognises ecological value but remains largely non-binding and incentive-oriented.

    Why are urban and coastal wetlands at special risk?

    1. Urban runoff absorption: Urban wetlands receive stormwater, sewage, and solid waste, increasing contamination.
    2. Flood buffering loss: Degradation converts wetlands into flood-prone zones rather than safety buffers.
    3. Coastal vulnerability: Mangroves and lagoons face dual pressures from landward development and rising seas.
    4. Disaster exposure: Weakens natural protection against cyclones, storm surges, and shoreline erosion.

    What governance failures constrain wetland conservation?

    1. Institutional capacity gaps: Limits state-level ability to manage complex hydrological systems.
    2. Sectoral silos: Separates water, land, urban planning, and environment decision-making.
    3. Limited accountability: Weak monitoring and absence of measurable performance indicators.
    4. Community exclusion: Undermines local stewardship and conflict resolution mechanisms.

    What pragmatic approaches can be taken?

    1. Watershed-scale planning: Ensures conservation beyond isolated wetland boundaries.
    2. Functional restoration: Prioritises ecological processes over aesthetic beautification.
    3. Demarcation and mapping: Strengthens legal clarity and dispute prevention through updated cadastral records.
    4. Infrastructure alignment: Integrates wetland protection into roads, embankments, and drainage planning.
    5. Institutional strengthening: Builds national capacity through training, accreditation, and governance reforms.

    How can technology strengthen wetland governance?

    1. Remote sensing: Enables real-time tracking of encroachment, inundation, and vegetation change.
    2. Drones and GIS: Improves mapping accuracy and monitoring frequency.
    3. Time-series analytics: Supports early warning and adaptive management strategies
    4. Revised NPCA guidelines: Allow science-based monitoring and management plans.

    Conclusion

    Wetlands cannot survive as isolated conservation projects. Treating them as national public goods demands integrated governance, functional restoration, institutional accountability, and community stewardship. India’s water security and climate resilience depend on this shift.

  • Carbon Border Adjustment Mechanism (CBAM)

    Why in the news?

    The European Union’s (EU) Carbon Border Adjustment Mechanism (CBAM) (CBAM) is a, as of January 1, 2026, fully implemented policy designed to levy a tax on carbon-intensive imports, such as steel, cement, aluminum, fertilizers, electricity, and hydrogen. This is applied to prevent “carbon leakage”. It ensures foreign producers pay a similar carbon price to EU firms, aiming to encourage global. It is in the news as it enters its decisive phase ahead of 2026, raising concerns for India’s carbon-intensive exports to the EU. Its relevance has increased after the conclusion of the India-EU Free Trade Agreement, which includes a non-discrimination (forward-MFN) clause on CBAM but does not remove the regulation itself.

    What is the Carbon Border Adjustment Mechanism (CBAM)?

    1. Carbon Pricing Instrument: Applies a carbon price on imports equivalent to the EU carbon price under the ETS.
    2. Leakage Prevention Tool: Prevents relocation of carbon-intensive production to jurisdictions with weaker climate policies.
    3. Climate-Trade Linkage: Integrates climate objectives directly into customs and trade regulation.
    4. WTO Compatibility Claim: Structured to mirror domestic carbon pricing to avoid discrimination.

    How Does CBAM Function in Practice?

    1. CBAM Certificates: Requires EU importers to purchase certificates reflecting embedded emissions.
    2. Price Benchmarking: Certificate prices linked to EU ETS allowance auction prices.
    3. Annual Compliance: Importers must declare embedded emissions and surrender certificates annually.
    4. Carbon Cost Deduction: Allows deduction if an equivalent carbon price is already paid in the exporting country.
    5. Equivalence Provision: Exempts exporters from jurisdictions with comparable carbon pricing regimes.

    What is the Implementation Timeline of CBAM?

    1. Transitional Phase (2023-2025):
      1. Reporting-only regime with quarterly disclosure of embedded emissions.
      2. No financial liabilities imposed.
    2. Definitive Regime (from 2026):
      1. Mandatory purchase and surrender of CBAM certificates.
      2. Threshold-based authorisation requirement for EU importers (above 50 tonnes).

    Which Sectors and Products are Covered?

    1. Iron and Steel: Includes selected downstream products such as nuts and bolts.
    2. Cement: High process emissions sector.
    3. Aluminium: Energy-intensive production profile.
    4. Fertilisers: Emissions from chemical processing.
    5. Electricity: Cross-border power imports.
    6. Hydrogen: Emerging but carbon-sensitive input.

    Together, these sectors account for over 50% of emissions in EU ETS-covered industries when fully phased in.

    Why Did the EU Introduce CBAM?

    1. Carbon Leakage Risk: Prevents displacement of emissions rather than their reduction.
    2. ETS Integrity: Supports tightening of the EU ETS by phasing out free allowances.
    3. Climate Ambition: Reinforces the EU’s 55% emissions reduction target by 2030.
    4. Trade Neutrality: Aligns treatment of domestic and imported goods.

    What are the Global and Economic Implications?

    • Emission Outcomes: OECD simulations indicate global emissions fall by 0.54% with CBAM, compared to 0.39% without it.
    • Trade Reorientation: EU importers shift sourcing towards cleaner producers.
    • Sectoral Spillovers:
      1. Covered EU industries regain domestic competitiveness but face export disadvantages.
      2. Downstream sectors face higher input costs without border protection.
    1. Country-Level Effects:
      1. Cleaner exporters (Chile, Mexico, Türkiye) gain marginally.
      2. Carbon-intensive exporters (India, South Africa) face modest export contraction (~0.2%).

    Why Does CBAM Matter for India?

    1. Export Exposure: India is a major exporter of iron, steel, aluminium, and fertilisers to the EU.
    2. Carbon Intensity Gap: Higher emissions intensity increases CBAM liability.
    3. Policy Equity Concerns: Raises questions of common but differentiated responsibilities.
    4. Administrative Burden: Requires robust emissions accounting and verification infrastructure.
    5. Diplomatic Engagement: EU’s acknowledgment of India’s concerns reflects negotiation space.

    Are there any regulatory concessions given to India on the CBAM regime after the India-EU FTA?  

    1. India secured a “forward-Most Favoured Nation (forward-MFN) clause on CBAM”, i.e., any future CBAM relaxations, flexibilities or concessions that the EU grants to other partners will automatically apply to India.
    2. Technical dialogue & cooperation: A structured technical dialogue to ease market access under CBAM and help exporters comply.
    3. Financial support pledge: The EU committed financing assistance (reported figure: ~€500 million over two years) to support India’s emissions reduction efforts.
    4. Rapid-response / rebalancing mechanism: Treaty language to rebalance rights if EU regulatory measures impair FTA benefits to Indian firms (safeguard-like clause).
    5. CBAM was not removed: The FTA does not repeal or exempt India from CBAM. The EU confirmed CBAM remains in place; the deal only ensures parity if the EU later gives concessions to others. CBAM remains operational.
    6. Plain effect of the forward-MFN clause: India will get the same future relaxations the EU grants other partners but CBAM still applies until and unless the EU changes its rules for everyone.

    Likely sectoral impact on India (concise, with editorial/analysis references)

    1. Steel (highest exposure): Continued cost pressure for flat-rolled and high-carbon products; EU remains a major buyer (e.g., ~44% of India’s steel exports to EU in some analyses), so impact on volumes and margins persists unless India decarbonises faster. .
    2. Aluminium: Risk of lower exports for high-emission aluminium; parity helps if EU later gives credits or recognition to cleaner producers, but immediate certificate costs remain.
    3. Cement & fertilisers: High process emissions mean persistent CBAM liability; cost pass-through to EU buyers limited, exporters will bear squeeze. 
    4. Downstream industries (autos, machinery): Indirect effect via higher input costs if upstream suppliers face CBAM costs; competitiveness may be affected for export-oriented value chains. 
    5. MSMEs: Disproportionate burden from verification and reporting costs, parity clause doesn’t reduce compliance complexity. Editorials warn of non-tariff barrier effects. .

    Conclusion

    The Carbon Border Adjustment Mechanism marks a structural shift in global trade, where climate regulation increasingly conditions market access. For India, CBAM poses real competitiveness and compliance challenges for carbon-intensive sectors, even as it aligns with the EU’s climate ambitions. The conclusion of the India–EU Free Trade Agreement provides limited but meaningful relief by securing a forward-Most Favoured Nation–type non-discrimination clause on CBAM, ensuring parity with any future concessions extended to other partners. However, the agreement does not dilute or suspend CBAM obligations, and carbon costs will continue to apply from 2026. Ultimately, the FTA mitigates relative disadvantage but does not eliminate structural pressures. India’s long-term response must therefore combine trade diplomacy with accelerated domestic decarbonisation, robust emissions accounting, and targeted support for vulnerable sectors to remain competitive in an increasingly climate-regulated global economy.
