Indian climate tech has moved from the margins of venture capital to one of its fastest-growing lanes. Annual funding into the sector climbed from $315 million in 2020 to $2.6 billion in 2025, a rise of more than eight times in five years, according to the India Climate Tech 2026 report from market intelligence platform Tracxn, released in June 2026. Cumulatively, Indian climate tech ventures have raised about $12.8 billion across 1,583 companies and 2,770 rounds, with 104 recorded exits. In the opening months of 2026, another $791 million flowed across 74 rounds, and roughly 66 percent of it landed in just five late-stage deals, a sign that capital is now chasing scale rather than early experiments.
Where the money is going
Renewable energy technology leads every other segment, drawing $1.5 billion across 195 rounds, per Tracxn. Solid waste management follows at $477 million, ahead of energy efficiency at $352 million, air pollution management at $237 million and water and wastewater at $208 million. Electric mobility, batteries and energy storage cut across those buckets and account for much of the deal volume.
The rounds that defined the cycle
- Erisha E Mobility booked the period's single largest cheque, a $1 billion commitment in March 2025 from an unnamed UAE-based investor, earmarked for EV and hydrogen manufacturing and overseas expansion.
- Euler Motors, a commercial EV maker, raised a ₹638 crore (about $75 million) Series D in May 2025 led by Hero MotoCorp, then a ₹437.5 crore (about $47 million) Series E in March 2026 led by Lightrock, with Hero MotoCorp and Blume Ventures returning.
- Battery Smart, a battery-swapping network, closed a $65 million Series B in June 2024 led by LeapFrog Investments, with MUFG Bank, Panasonic, Blume Ventures, British International Investment and existing backer Tiger Global.
- Lohum, a battery-recycling and energy-transition materials firm, raised a $54 million (₹450 crore) Series B in March 2024, with Singularity Growth and Baring Private Equity among the backers.
- Ecozen, which builds solar-powered cooling and farm technology, drew $30 million in April 2024 from Nuveen and debt lenders, then opened a Series C in 2025 led by Dare Ventures.
- 75F, a building energy-efficiency platform, raised a $45 million Series B in early 2025 led by Accurant International, with Breakthrough Energy Ventures, Climate Investment and Carrier Global participating.
Why capital is flowing
The clearest driver is energy security. With roughly 85 percent of India's crude oil imported, Tracxn notes that renewables, electric mobility, storage and critical minerals are now treated as strategic infrastructure, not just green bets. Policy reinforces the shift: production-linked incentive schemes for advanced batteries and solar, the FAME program for electric vehicles, and a national target of 450 GW of renewable capacity by 2030 give investors a demand signal that lasts beyond any single funding cycle.
Development finance is doing much of the heavy lifting. British International Investment alone has backed Euler Motors, GreenCell Mobility and Ecofy, and institutions including the International Finance Corporation, FMO and Finnfund appear across the larger rounds, alongside private backers such as Lightrock, LeapFrog, Tiger Global, Blume Ventures and Breakthrough Energy Ventures. The final piece is proof of exits: Tracxn counts 104 to date, and Ather Energy's May 2025 public listing gave the sector its clearest liquidity milestone yet. The capital is following returns, not just goodwill.
