A surge in clean energy has kept carbon dioxide (CO2) emissions in check across India’s power sector, with no growth from the first half of 2024 to the same period in 2026.
This is the first time in more than 50 years that there has been no growth in India’s coal power over a two-year period, even as electricity demand grew overall.
At the same time, both oil and gas consumption have fallen across the nation for two years in a row, helping alleviate the shock of the Hormuz crisis.
Nevertheless, the new six-monthly analysis for Carbon Brief shows that India’s emissions grew by 3.7% year-on-year in the first half of 2026, due to increases from steel, cement and other sectors.
Other key findings for the first half of 2026 include:
- India’s power-sector emissions flatlined at 2024 levels, after a 2.2% decline in the first half of 2025 and a 2.3% rise in the same period this year.
- Clean energy met all of the 7% rise in India’s electricity demand over the two years, adding 63 terawatt hours (TWh), equivalent to the total demand of Switzerland.
- India has added 77 gigawatts (GW) of solar in this two-year period, helping meet 60% of the rise in electricity demand overall.
- While fossil-fuel generation stagnated, generators added 8.5GW of new coal capacity, leading to fewer running hours and increased costs to electricity consumers.
- CO2 emissions from oil and gas fell by 7% year-on-year, extending a reduction that began in 2025, despite higher demand for road transport fuels.
- Steel and cement emissions grew by 8% year-on-year, reaching a 23% share of India’s total CO2 in the first half of 2026.
If the pace of India’s clean-energy expansion is to continue, it will need to upgrade its electricity grid, rapidly build out energy storage and boost the flexibility of coal power.
While clean-energy expansion is covering most or all of India’s power-demand growth, the fossil-fuel industry continues to pursue major capital investments.
This includes large amounts of new coal-power capacity, ambitious plans for the conversion of coal-to-chemicals and efforts to boost domestic coking coal production for the steel sector.
While CO2 output from the power sector is flat, with oil and gas in decline, India’s emissions still went up due to the contribution from industry.
India lags behind its competitors – including most large emerging economies – when it comes to electrifying its industrial sector.
Faster progress would enable clean electricity to substitute for fossil fuels in industry, as well as for power, offering the potential for India to cut its emissions overall.
