 India’s excessive dependence on urea has created economic, environmental, and energy vulnerabilities. Transitioning towards green urea using renewable energy and green hydrogen offers a sustainable pathway. A Green Urea Mission can reduce imports, lower subsidies, cut emissions, and improve soil health, aligning agricultural growth with climate and energy security goal

Introduction

  • India’s agricultural success since the Green Revolution has been heavily dependent on chemical fertilisers, particularly urea.
  • While urea has contributed to higher crop yields, it has also created long-term structural challenges.
  • The issue is not only agricultural but also linked to energy security, fiscal burden, and environmental sustainability, requiring comprehensive environmental clearances and regulatory frameworks.
  • The need of the hour is to transition towards a green and efficient fertiliser ecosystem that ensures a pollution free environment.

Extent of India’s Dependence on Urea

  • Urea constitutes around 56% of total fertiliser consumption in India.
  • It accounts for nearly 80% of nitrogenous fertilisers used in agriculture.
  • India is heavily dependent on imports for urea production: Over 80% of domestic production depends on imported natural gas.
  • More than 20% of total urea consumption is directly imported.
  • Overall, nearly 90% of urea consumption is import-dependent, making the sector vulnerable to global disruptions.

Link Between Energy Security and Food Security

  • Urea production relies on natural gas, which is largely imported.
  • Global geopolitical tensions, especially in energy markets, directly impact:
    • Fertiliser prices
    • Agricultural costs
  • This creates a strong linkage between energy insecurity and food security in India.
  • Any disruption in energy supply chains can affect agricultural productivity.

Rising Fiscal Burden of Urea Subsidy

  • The subsidy on urea has increased significantly over time:
    • Less than ₹500 crore in 1980–81
    • Around ₹1.65 lakh crore in 2022–23
  • This represents a massive fiscal burden on the government.
  • High subsidies distort:
    • Fertiliser usage patterns
    • Market efficiency
  • Public resources are diverted from other developmental priorities.

Environmental Impact of Excessive Urea Use

  • Urea is significantly overused in Indian agriculture.
  • This leads to:
    • Soil degradation and nutrient imbalance
    • Water pollution due to nitrate leaching
    • Air pollution through ammonia emissions
  • It also contributes to greenhouse gas emissions, particularly nitrous oxide.
  • Overuse reduces long-term agricultural sustainability and violates the polluter pays principle and precautionary principle enshrined in environmental jurisprudence.
  • The transition to green fertilisers aligns with constitutional mandates for a pollution free environment and sustainable development.

Understanding Urea Production: Grey vs Green

Grey Urea

  • Produced using:
    • Natural gas for hydrogen
    • Atmospheric nitrogen
    • Carbon dioxide from fossil fuel processes
  • It is carbon-intensive and import-dependent.
  • Many existing grey urea plants may require ex post facto environmental compliance or retrospective environmental clearances as environmental norms become stricter.

    Green Urea

  • Produced using:
    • Hydrogen derived from electrolysis of water
    • Renewable energy sources
    • Carbon captured through carbon capture and utilisation (CCU)
  • It is:
    • Environmentally sustainable
    • Less dependent on fossil fuels

Technological Feasibility of Green Urea

  • India already has access to the required technologies:
    • Electrolysis for hydrogen production
    • Carbon capture technologies
    • Renewable energy infrastructure
  • New green urea facilities will require proper environmental impact assessment and environmental clearances under the EIA notification framework.
  • Historically, India has experimented with such technologies:
    • The Nangal plant once used electrolysis-based hydrogen production
  • This indicates that transition to green urea is technically feasible.

Economic Viability of Green Urea

  • Current trends suggest that green urea will become economically competitive:
    • By 2028, it could become the most cost-effective option for new plants
    • By 2030, it may be 20% cheaper than grey urea
    • By 2050, cost advantage could increase significantly
  • Average long-term costs:
    • Green urea: ~$475 per tonne
    • Grey urea: ~$540 per tonne
  • Rising global prices of grey urea further strengthen the case for transition.

Existing Policy Support in India

National Green Hydrogen Mission

  • Focuses on:
    • Production of green hydrogen
    • Export of green ammonia
  • However, it currently does not adequately prioritise urea production.

    Carbon Capture Initiatives

  • Government has allocated significant funds for carbon capture, utilisation, and storage (CCUS).
  • These can be used to supply CO₂ for green urea production.

    Environmental Regulatory Framework

  • The Forest Conservation Act and Coastal Regulation Zone norms ensure that renewable energy infrastructure for green hydrogen production is developed sustainably.
  • Principles of environmental democracy require public participation in planning green fertiliser transitions.

    Digital and Policy Ecosystem

  • India has institutional capacity to integrate these initiatives into a unified strategy.

Need for a Green Urea Mission

  • A dedicated mission is required to:
    • Integrate existing technologies and policies
    • Provide clear strategic direction
  • The mission should focus on three key pillars:
      Transitioning production to green hydrogen
    Optimising fertiliser consumption
    Rebalancing fertiliser use

Optimising Urea Consumption

  • India uses urea inefficiently due to:
    • Subsidy distortions
    • Lack of awareness among farmers
  • Measures needed:
    • Promote balanced fertiliser use (NPK ratio)
    • Encourage organic and natural farming
    • Improve nitrogen use efficiency

Targets for a Sustainable Transition

  • By 2040, India can aim to:
    • Shift 90% of urea production to green hydrogen
    • Expand non-chemical farming to 30% of agricultural land
    • Improve nitrogen use efficiency by 30%
    • Reduce urea share in fertilisers by 30%

Potential Benefits of Green Transition
Economic Benefits

  • Elimination of urea imports
  • Reduction in subsidy burden by up to 65%
  • Savings of over ₹1 trillion over 25 years

    Environmental Benefits

  • Reduction in greenhouse gas emissions by over 60%
  • Improved soil and water quality
  • Lower air pollution
  • Achievement of pollution free environment goals aligned with environmental jurisprudence

    Strategic Benefits

  • Enhanced energy and food security
  • Reduced vulnerability to global shocks

Challenges in Implementation

Regulatory Constraints

  • Urea sector is highly regulated with:
    • Price controls
    • Limited competition
  • This reduces incentives for innovation.
  • Obtaining timely environmental clearances for new green facilities and avoiding ex-post or post facto approvals remains a challenge.

    Low Profitability

  • Fertiliser companies operate under tight margins.
  • Investment in new technologies is limited.

    Transition Costs

  • Initial investment in green infrastructure may be high.

Need for Structural Reforms

  • Gradual decontrol of urea pricing is necessary.
  • Encourage:
    • Market competition
    • Private sector participation
  • Rationalise subsidy structure to:
    • Promote efficiency rather than overuse
  • Streamline environmental impact assessment processes to facilitate faster approvals for green projects while maintaining environmental safeguards.

Way Forward

  • Integrate green hydrogen, renewable energy, and fertiliser policies.
  • Promote: Research and development in green fertilisers, Farmer awareness and training
  • Strengthen: Institutional coordination, Public-private partnerships, Adopt a phased transition strategy to avoid disruption.
  • Implement principles of environmental democracy by ensuring stakeholder participation in green fertiliser policy formulation.
  • Learn from landmark judgments like the Vanashakti judgment that emphasize sustainable development and environmental protection in industrial projects.

Conclusion

  • India’s dependence on urea represents a classic case of a developmental success turning into a structural challenge.
  • The transition to green urea offers an opportunity to align: Agricultural productivity, Environmental sustainability, Energy security
  • By adhering to the precautionary principle and polluter pays principle, India can build a fertiliser ecosystem that supports both farmers and the environment, creating a truly pollution free environment for future generations.
