Not Started

1. Context: India’s Climate Commitments under the Paris Agreement

  • India submitted its Nationally Determined Contributions (NDCs) at the Paris Climate Summit (2015).
  • Commitments were framed under the principle of Common But Differentiated Responsibilities (CBDR).
  • India emphasised developmental needs due to historically low per capita emissions, despite rising absolute emissions.
  • India is currently the world’s third-largest absolute emitter, increasing scrutiny on outcomes rather than intent.

Key Commitments

  • Reduce emissions intensity of GDP by 33–35% from 2005 levels by 2030
  • Achieve 40% non-fossil fuel-based power capacity (later raised to ~50%)
  • Create 2.5–3 billion tonnes CO₂e additional carbon sink through forests
  • Scale up renewable energy capacity (175 GW by 2022; 500 GW by 2030 ambition)

2. Emissions Intensity Reduction: Achievements and Limits

  • India reduced emissions intensity by approximately 36% by 2020, meeting the Paris target early.
  • This reflects relative (partial) decoupling—GDP growth outpacing emissions growth.

Drivers of Intensity Reduction

  • Expansion of non-fossil power capacity
  • Structural shift toward services and digital economy
  • Energy efficiency programmes such as:
    • Perform, Achieve and Trade (PAT)
    • UJALA LED programme

Limitation

  • Absolute emissions remain high at around 2,959 MtCO₂e in 2020.
  • Intensity reduction does not equate to total emissions decline.

3. Sectoral Emissions and Structural Divergence

  • Aggregate intensity metrics mask sectoral variations.
  • Emissions from cement, steel, and transport continue to rise.
  • Power sector emissions growth moderated in 2024–25, but coal remains dominant.

Implications

  • Industrial decarbonisation and transport electrification remain weak.
  • Without sector-specific strategies, future intensity gains may plateau.

4. Renewable Energy Capacity Expansion

  • Non-fossil fuel capacity increased from ~29.5% (2015) to ~51.4% (June 2025).
  • Solar power grew from 2.8 GW (2014) to ~110.9 GW (2025).
  • Wind power increased to ~51.3 GW, but growth slowed due to land and grid constraints.

Government Schemes

  • National Solar Mission
  • Solar Parks Scheme
  • PM-KUSUM
  • Rooftop Solar Programme
  • UDAY (DISCOM reforms)

5. Capacity vs Generation Gap

  • Despite over 50% non-fossil capacity, renewables contributed only ~22% of electricity generation in 2024–25.
  • Coal-based thermal power:
    • Installed capacity: ~240–253 GW
    • Contribution to generation: >70%

Reasons

  • Lower capacity factors of solar and wind
  • Intermittency of renewables
  • Inadequate energy storage
  • Grid congestion and transmission delays

6. Energy Storage and Grid Constraints

  • Central Electricity Authority projects 336 GWh storage requirement by 2029–30.
  • Actual operational battery storage as of September 2025: ~500 MWh.

Challenges

  • Delayed grid connectivity
  • Limited transmission upgrades
  • Land acquisition issues
  • State-level regulatory bottlenecks

Impact

  • Renewable capacity fails to displace coal baseload.
  • Risk of stranded green assets.

7. Forest Carbon Sink Target: Progress and Measurement Issues

  • India committed to 2.5–3 billion tonnes CO₂e additional forest carbon sink by 2030.
  • India State of Forest Report 2023:
    • Total forest carbon stock: 30.43 billion tonnes CO₂e
    • Increase since 2005: 2.29 billion tonnes
    • Remaining gap: ~0.2 billion tonnes

Measurement Concern

  • Forest Survey of India defines forest cover as:
    • Land ≥1 hectare
    • ≥10% canopy density
  • Includes plantations, monocultures, orchards, and roadside trees.

8. Afforestation Governance and Ecological Quality

  • Compensatory Afforestation Fund Act (2016):

    • Funds accumulated: ~₹95,000 crore
    • Utilisation uneven across states
    • Example: Delhi utilised only 23% (2019–20 to 2023–24)

  • Green India Mission (Revised, 2025):

    • Target: 5 million hectares
    • Focus regions: Aravallis, Western Ghats, Himalayas
    • Plantation often equated with natural regeneration

Ecological Concerns

  • Plantations lack biodiversity and resilience.
  • Climate stress reduces net primary productivity despite visible “greening.”

9. Environmental Governance and Judicial Role

  • Judicial interventions like the Aravalli judgment highlight weak regulatory enforcement.
  • Mining and infrastructure projects often conflict with ecological safeguards.
  • Environmental clearance processes risk becoming procedural rather than substantive.

Governance Issue

  • Courts compensate for regulatory gaps but cannot replace institutional capacity.

10. Way Forward: Translating Targets into Outcomes

Key Priorities

  • Scale up battery energy storage rapidly
  • Establish a transparent coal transition roadmap
  • Strengthen industrial decarbonisation strategies
  • Reform forest governance to prioritise ecological integrity
  • Improve data transparency across sectors and regions

Conclusion

  • India has largely delivered on its quantified climate commitments.
  • However, absolute emissions remain high, coal dominates generation, and forest targets rely on accounting practices.
  • The next five years are critical to convert headline achievements into durable climate outcomes through coordinated governance and systemic reform.

Quick Q&A

Everything you need to know

India committed to reducing its greenhouse gas (GHG) emissions intensity by 33-35% from 2005 levels by 2030 under the Paris Agreement. This target measures emissions per unit of GDP rather than absolute emissions, allowing economic growth alongside mitigation.

Three key drivers enabled India to achieve intensity reduction ahead of schedule:

  • Expansion of non-fossil power capacity: Solar, wind, hydro, and nuclear capacity increased rapidly, reaching ~50% of total installed capacity by mid-2025.
  • Economic structural shift: Growth in lower-carbon service and digital sectors reduced emissions per unit of GDP.
  • Efficiency programs: Initiatives like PAT (Perform, Achieve, and Trade) and UJALA promoted energy efficiency in industry and households, avoiding significant emissions.

However, absolute emissions remain high (~2,959 MtCO₂e in 2020), illustrating partial decoupling where GDP growth outpaces emissions growth. This underscores that while intensity gains are commendable, they do not equate to reductions in total emissions.

Despite reaching ~51% non-fossil fuel capacity by June 2025, the share of electricity generated from renewables remains low (~22% in 2024-25). The reasons include:

  • Intermittency: Solar and wind operate variably based on weather, resulting in lower capacity factors compared to coal.
  • Storage bottlenecks: Limited battery storage (~500 MWh operational vs. 336 GWh forecast demand by 2029-30) prevents surplus renewable energy from being effectively dispatched.
  • Grid and land constraints: Delays in grid connectivity and restricted land acquisition reduce the ability to translate installed capacity into sustained generation.

Consequently, coal-based thermal plants (~253 GW) continue to provide baseload power. While capacity expansion is a policy success, actual emissions reduction remains constrained until renewable integration, storage, and grid flexibility are enhanced.

India’s forest cover is defined broadly to include any land over one hectare with at least 10% canopy cover, encompassing eucalyptus monocultures, plantations of mango, tea, and roadside trees, alongside natural forests. While official reports suggest that India will meet its carbon sequestration target of 2.5-3 billion tonnes by 2030, the ecological reality differs:

  • Plantation vs natural forest: Carbon accounting often equates plantations to natural regeneration, which may not deliver comparable biodiversity or ecological benefits.
  • Implementation gaps: Under the Compensatory Afforestation Fund Act, ~₹95,000 crore has been allocated, but some states like Delhi have utilised only 23% of funds.
  • Climate stress: Warming and water stress affect forest productivity, particularly in the Western Ghats and northeastern India.

Thus, while numerical targets are on track, the qualitative ecological outcomes remain uncertain, highlighting the need for improved governance and monitoring beyond performative metrics.

Absolute emissions in India remain high due to multiple structural factors:

  • Coal dependence: Thermal power continues to provide ~70% of electricity generation despite non-fossil capacity being >50%.
  • Sectoral divergence: Industrial sectors such as cement, steel, and transport have rising emissions, offsetting reductions in power-sector CO₂ growth.
  • Partial decoupling: GDP growth outpaces emission growth; while efficiency improves intensity metrics, total emissions remain elevated.

For India to meet its net-zero pledge by 2070, intensity gains must be converted into absolute reductions through coal phase-down plans, industrial decarbonisation strategies, and systemic interventions that address high-emission sectors comprehensively.

A practical example is solar energy deployment: Installed solar capacity expanded from ~2.8 GW in 2014 to ~110.9 GW by mid-2025, yet it supplied a limited portion of electricity (~22%) in 2024-25 due to intermittency and storage gaps. Even as rooftop solar, the National Solar Mission, and Solar Parks added ~25 GW annually, delays in grid connectivity and insufficient battery storage (~500 MWh operational vs. 336 GWh forecast) constrained actual utilisation.

This illustrates that capacity targets alone do not ensure emissions reduction. Effective integration, storage scaling, and grid upgrades are critical to convert installed renewable capacity into reliable, dispatchable electricity, reinforcing the difference between headline metrics and on-ground climate impact.

While India reports that ~2.5-3 billion tonnes of CO₂ equivalent will be sequestered by 2030, several issues challenge the credibility of these efforts:

  • Quantitative vs qualitative: Numerical targets rely heavily on plantations and monocultures rather than ecological restoration.
  • Implementation gaps: States vary widely in fund utilisation and project execution, leading to inconsistent outcomes.
  • Climate stress and biodiversity: Water stress and warming reduce net primary productivity, particularly in ecologically sensitive regions like the Western Ghats and northeast.

Thus, while carbon accounting shows progress, forest governance needs systemic reform to ensure ecological integrity, biodiversity conservation, and resilience, aligning carbon targets with on-ground environmental outcomes.

A multi-pronged strategy is required to translate intensity improvements into absolute emission reductions:

  • Coal phase-down: Develop a transparent roadmap for gradual retirement of coal plants, replacing them with dispatchable renewables and storage.
  • Grid and storage infrastructure: Rapidly scale battery storage, transmission upgrades, and grid management systems to accommodate intermittent renewable generation.
  • Industrial decarbonisation: Target high-emission sectors like cement, steel, and transport with efficiency standards, cleaner technologies, and electrification.
  • Enhanced forest governance: Prioritise natural regeneration, biodiversity outcomes, and state-level fund utilisation to ensure carbon sinks are effective.

For instance, integrating rooftop solar, solar parks, and PM-KUSUM schemes with grid storage could reduce reliance on coal baseload, while focused industrial interventions could address sectoral emission hotspots. Coordinated policy implementation and data transparency are critical to ensure that India’s climate ambitions align with ecological reality.
