These are the top climate tech startups in India leading that charge in 2026. For a deeper look at how these startups tackle India’s biggest crises, read our companion piece: How Indian Climate Startups Are Solving India’s 5 Biggest Environmental Problems.

India’s climate tech startups in 2026 are backed by global investors and solving problems that affect over a billion people. According to Climafix, the sector has attracted $12.8 billion in funding across 1,583 companies. For a global view on clean energy trends, the IEA World Energy Investment 2024 report confirms India is the second-fastest-growing clean energy market on Earth.
What Are Climate Tech Startups India 2026? Definition and Scope
Climate tech startups India 2026 are companies using technology to reduce greenhouse gas emissions, adapt to climate change, or remove carbon from the atmosphere. They operate across solar energy, electric vehicles, waste management, carbon markets, clean water, and sustainable agriculture — and they are increasingly well-funded and globally connected.
1. Ecozen Solutions — Solar Cold Chains for Indian Farmers
Founded by Devendra Gupta, Prateek Singhal, and Vivek Pandey, Ecozen Solutions builds solar-powered cold rooms and irrigation systems that help farmers cut post-harvest losses dramatically. Their flagship Ecofrost solar cold room runs without the grid — critical for the 70% of Indian farmers who lack reliable electricity. Their Ecotron irrigation controller reduces water waste by up to 60%.
Ecozen has raised approximately $104 million in debt and equity, including a $30M round backed by Nuveen, InCred, and the US Development Finance Corporation. India loses an estimated ₹92,000 crore in fruit and vegetables annually due to poor cold storage — Ecozen is solving that directly.
2. GPS Renewables — Turning Agricultural Waste Into Clean Fuel
Founded by Mainak Chakraborty and Sreekrishna Sankar, GPS Renewables builds and operates biogas, bioCNG, and ethanol plants that convert agricultural and industrial waste into clean fuel. In June 2026, the company raised a ₹635 crore Series C led by PixelSky Capital — one of the largest climate tech raises in India this year.
India generates over 350 million tonnes of agricultural waste annually. GPS Renewables turns that waste stream into a clean energy asset, while reducing the stubble burning that chokes north Indian cities every winter.
3. Exponent Energy — 15-Minute EV Charging
Founded by Arun Vinayak, Exponent Energy has built a fast-charging system for electric three-wheelers and buses that charges to 100% in just 15 minutes — transforming the economics of commercial EV fleets in India. The company has raised $65.7 million total, including a ₹200 crore round led by TDK Ventures and 360 ONE Asset in June 2026.
Slow charging is the single biggest adoption barrier for electric commercial vehicles in India. Exponent removes that barrier entirely, making electric fleets viable for logistics and public transport operators.
4. Battery Smart — 60-Second Battery Swaps at 1,600+ Stations
Founded by Pulkit Khurana and Siddharth Sikka, Battery Smart runs India’s largest battery swapping network for electric two- and three-wheelers, with over 1,600 stations nationwide. Drivers swap a depleted battery for a fully charged one in under 60 seconds — no waiting, no downtime.
The company has raised over $192 million from Tiger Global, British International Investment, LeapFrog Investments, MUFG Bank, and Panasonic. Over 85% of new electric vehicles sold in India are two- and three-wheelers — Battery Smart makes those vehicles viable for gig economy drivers.
5. Chakr Innovation — Converting Diesel Exhaust Into Ink
One of the standout climate tech startups India 2026 investors are backing is Chakr Innovation. Founded by Kushagra Srivastava and Arpit Dhupar, Chakr Innovation makes the Chakr Shield — a retrofittable device that captures over 80% of particulate matter from diesel generator exhaust and converts it into ink and coatings. The company raised a $23 million Series C led by Iron Pillar in September 2025.
India has an estimated 15 million diesel generators running daily, making them one of the country’s largest unregulated pollution sources. Chakr turns that pollution into a commercial product.
6. Varaha — Carbon Credits From India’s Farmland
Varaha is among the climate tech startups India 2026 breaking into global carbon markets. Founded by Madhur Jain, Ankita Garg, and Vishal Kuchanur, Varaha generates verified carbon removal credits from regenerative farming, agroforestry, and biochar projects across India — selling them to global corporates meeting net-zero commitments. Varaha has raised approximately $33 million, including a $20M tranche from a planned Series B led by WestBridge Capital in February 2026.
7. Recykal — A Digital Marketplace for India’s Waste Economy
Founded by Abhay Deshpande and Abhishek Deshpande, Recykal connects waste generators, collectors, and recyclers on a single digital platform — and helps companies fulfil Extended Producer Responsibility (EPR) obligations under Indian law. The company has raised $40.9 million from Morgan Stanley, Circulate Capital, and 360 ONE Asset Management.
8. Newtrace — Green Hydrogen Without Platinum
Founded by Prasanta Sarkar and Rochan Sinha, Newtrace has developed Voltagen — an electrode coating that cuts energy consumption in green hydrogen electrolysers by up to 30% without using expensive platinum-group metals. The company has raised approximately $12 million, including $6.3M led by Mitsui Sumitomo Insurance Venture Capital and HDFC Bank.
9. Alt Carbon — Rock Dust That Removes CO₂ From the Atmosphere
Alt Carbon uses enhanced rock weathering — spreading crushed basalt on agricultural land — to permanently remove CO₂ from the atmosphere while improving soil fertility. The startup raised a $12 million seed round and is piloting across Indian farmland, with farmers earning payments for hosting the basalt. It is one of the few carbon removal methods that works at agricultural scale.
10. Zerocircle — Seaweed Packaging That Dissolves in the Ocean
Founded by Neha Jain, Zerocircle makes compostable and marine-degradable packaging from farmed seaweed — replacing plastic films, bags, and wraps for food and consumer goods companies. The company has raised approximately $4.9 million, including ₹20 crore led by Rainmatter. India generates over 3.5 million tonnes of plastic waste annually — Zerocircle’s packaging dissolves harmlessly if it reaches the ocean.
