For the first time outside the COVID-19 years, India's power sector saw a 1% drop in CO2 emissions during January to June 2025 compared to the same period in 2024, as per a latest analysis by the Centre for Research on Energy and Clean Air (CREA) for Carbon Brief. This milestone in the sector, which contributes nearly 40% of India's total greenhouse gas emissions, signals a potential early peak in power-related emissions by 2030, supporting the country's push towards 500 GW non-fossil capacity by 2030 and net-zero by 2070. The dip comes amid record renewable additions and milder weather, highlighting progress in India's clean energy transition.
What does this CO2 emissions dip mean for India's power sector?
This 1% decline in power sector emissions is a rare break from the usual upward trend tied to economic growth, showing how renewables and weather can bend the curve towards sustainability.
Historical Context:
India's power emissions have risen steadily for decades, contributing 37% to global energy CO2 growth since 2019; this is just the second drop in 50 years, the first being a COVID dip in 2020, as per CREA data analyzed for Carbon Brief.
Current Data Breakdown:
Emissions fell by 5 million tonnes in Jan-Jun 2025 vs 2024, with fossil generation down 29 TWh despite 9 TWh total rise; clean sources covered the gap, generating nearly 50 TWh extra annually from new capacity.
Significance for Transition:
It proves India's renewable push is working, with non-fossil share at 25% in 2024-25 rising to projected 44% by 2029-30 per Central Electricity Authority, potentially flat-lining coal output.
What caused the decline in emissions this year?
Lower demand from weather and faster clean energy rollout cut reliance on coal, which powers 70% of India's electricity, allowing emissions to dip even as the economy grew 7%.
Weather and Demand Factors:
Milder heatwaves and 30-42% excess rainfall cut cooling needs by 10%; industrial slowdown and monsoon disruptions further slowed demand growth to 6% annually.
Renewable Acceleration:
25.1 GW added included 62% solar, 16% hydro, 13% wind, and 8% nuclear; rooftop solar hit 3.2 GW, boosting decentralized green power and reducing grid strain.
Coal and Fossil Trends:
Power coal use dropped 0.2% over 12 months to June 2025; gas fell 7%, but new 35 GW coal plants under construction could challenge gains if not managed.
How does this fit into India's renewable energy targets?
The dip aligns with bold goals like 500 GW non-fossil by 2030, already at 252 GW, showing early wins but needing storage and grid upgrades to sustain.
Achievement Milestones:
India hit 50% non-fossil capacity in July 2025, five years ahead; 234 GW renewables in pipeline, with 145 GW under construction, could near 482 GW by decade-end.
Projected Growth:
CEA forecasts clean sources to meet all demand rise from 2025-30; solar-wind with batteries could replace peak coal use, cutting costs and emissions further.
Challenges Ahead:
Despite records, coal targets of 80-100 GW addition by 2032 risk overcapacity; experts urge policy focus on retiring old plants for true peak.
What are the broader implications for India's climate goals?
This could lead to power emissions peaking by 2030, easing path to net-zero by 2070, but overall emissions need industry curbs as power alone is 40% of total.
NDC and Global Context:
India's current NDC cuts intensity 45% by 2030 from 2005 levels, likely to be met early; new 2035 NDC due September 2025 must address transport and steel rises.
Economic and Social Gains:
Lower emissions save on fuel imports (India imports 80% coal), create green jobs in 1 million+ solar installs, and support Viksit Bharat with cheaper power at Rs 2-3/kWh from renewables.
Global Role:
As third-largest emitter, India's dip counters 4.6% fossil rise projected for 2024; it boosts credibility in COP talks, pushing for fair finance from developed nations.
How does this compare to past trends and global peers?
India's dip bucks Asia's coal reliance, where China added 47 GW coal in 2023; it mirrors EU's renewable shift but at faster pace, driven by domestic solar manufacturing.
Past Indian Trends:
Emissions grew 10% yearly in 2021-23 with coal boom; 2025 slowdown is slowest since 2001, with oil flat vs 6% rise in 2023.
Global Benchmarks:
Unlike US (down 3% power emissions 2024 via gas shift), India's is renewable-led; peers like Vietnam still add coal, making India a model for Global South transitions.
Future Outlook:
If sustained, power peak by 2030 could cut total emissions 20-30% vs business-as-usual, per Climate Action Tracker, aiding Paris goals.
