- Alt Carbon, a Bengaluru- and Darjeeling-focused climate-tech StartUp, has raised about 12 million dollars (roughly in the mid double-digit crore range) to scale enhanced rock weathering projects that remove carbon while improving soil health.
- Microsoft has signed a multi-year deal to buy nearly 37,000 tonnes of carbon removal credits from Alt Carbon’s Darjeeling Revival Project—its first enhanced rock weathering contract in Asia, signaling global validation for Indian ClimateTech.
- India’s climate-tech funding has seen a slowdown, with PE/VC investments dropping from around 1.66 billion dollars in 2023 to about 270 million dollars in the first half of 2025, but impact-focused investors remain active.
- Climate-tech investment now spans carbon removal, regenerative agriculture, water management, waste-to-energy, clean mobility and sustainable agriculture, backed by dedicated funds like Climate Angels and others.
- Many new founders in this space come from agriculture, engineering colleges and rural innovation labs, building solutions for village-level problems while tapping into global markets for carbon credits and climate services.
India’s ClimateTech wave is expanding far beyond solar panels and companies like Alt Carbon show how deep the shift runs from carbon removal and regenerative agriculture to water, waste and village-level livelihoods.
Even as funding cycles wobble, investors and customers now increasingly look for measurable environmental impact backed by solid business models.
What if the field behind your village could become both a farm and a carbon sink?
India’s new wave of ClimateTech StartUps from carbon-removal ventures like Alt Carbon to regenerative agriculture and waste innovators, is quietly solving everyday problems while aiming for millions of tonnes of verifiable climate impact.
ClimateTech in India is no longer limited to rooftop solar or large solar parks; it now spans water management, waste recycling, regenerative agriculture, carbon removal and clean manufacturing.
Alt Carbon is a strong example: a deep-tech StartUp using enhanced rock weathering to lock carbon into rocks and soils while reviving degraded tea landscapes in Darjeeling and similar regions.
The company has raised a sizeable seed round, reported as the largest climate-tech seed round in India, to expand Earth sciences R&D and hardware, with a target of removing around 5 million tonnes of CO? by 2030.
Its Darjeeling Revival Project turns farms into long-term carbon sinks, blending climate action with livelihood restoration for tea growers. Microsoft’s multi-year agreement to buy nearly 37,000 tonnes of carbon removal credits from Alt Carbon marks its first enhanced rock weathering deal in Asia and signals rising confidence in Indian ClimateTech.
Broader trends show both opportunity and pressure: while climate-tech funding in India has dipped since 2023, impact-focused funds still back sectors such as regenerative agriculture, waste-to-energy and sustainable mobility, rewarding StartUps that can prove measurable environmental outcomes and resilient business models.
Five salient points from the ecosystem:
- Alt Carbon uses enhanced rock weathering to remove CO? from the atmosphere while improving soil health and reviving tea-based livelihoods in projects like the Darjeeling Revival initiative.
- Microsoft’s first Asia-based enhanced rock weathering deal is with Alt Carbon, covering nearly 37,000 tonnes of carbon removal credits and signalling global demand for verifiable ClimateTech from India.
- Dedicated investors such as Climate Angels are focusing on climate-tech segments including clean mobility, sustainable agriculture, water management, waste reduction and the built environment.
- Regenerative agriculture approaches promoted by agri-tech players aim to restore soil health, water cycles and biodiversity while sequestering carbon, though farmers face upfront cost and yield challenges.
- Despite a funding slowdown, climate-tech still attracts a significant share of venture capital compared to other sectors, pushing founders to design models with clear environmental metrics and long-term resilience.
India’s ClimateTech story is shifting from big, shiny assets to gritty, village-level interventions that make fields healthier, water cleaner and livelihoods more resilient. For #EntrepreneursinIndia, the message is clear: the next wave of #makeinindia ClimateTech will reward patient science, farmer partnerships and auditable impact—not just slogans.
