What is Climate Tech?
Climate tech refers to technology-driven solutions designed to address climate change. This includes innovations in:
Carbon reduction and removal
Renewable energy
Sustainable agriculture
Clean transportation
Circular economy and waste reduction
Unlike traditional environmental initiatives, climate tech is backed by venture capital, software-first thinking, and scalable deployment models. It’s where startup speed meets global impact.
Why It Matters
Climate tech startups are tackling some of the toughest systemic problems: emissions, inefficiencies, pollution, and energy dependency. With increasing investor interest, supportive policies, and rising public awareness, the sector has grown from niche to mainstream.
As of 2024, over 80 climate tech unicorns have emerged, according to HolonIQ, and the market is projected to exceed $2 trillion by 2030.
This isn’t just a feel-good space—it’s a massive innovation opportunity.
Top 10 Climate Tech Startups Making Waves
Here’s a curated list of 10 standout startups in climate tech—across energy, carbon, food, and materials—each reimagining how we live and consume.
1. Climeworks (Switzerland)
What they do: Direct Air Capture
Climeworks builds machines that suck CO₂ directly from the air and store it underground permanently. They’re one of the most advanced players in the carbon removal race.
2. Charm Industrial (USA)
What they do: Bio-oil Carbon Removal
Charm turns plant waste into bio-oil and injects it into rock formations to sequester carbon for thousands of years. A new take on permanent carbon removal.
3. Solugen (USA)
What they do: Carbon-negative chemicals
Solugen produces chemicals using engineered enzymes instead of petroleum-based processes—cutting emissions from a traditionally high-polluting industry.
4. Twelve (USA)
What they do: Carbon transformation
Twelve uses electrochemistry to turn CO₂ into products like jet fuel, plastics, and detergents—effectively replacing fossil fuels with captured carbon.
5. Heirloom (USA)
What they do: Enhanced mineralization
Heirloom speeds up the natural process of minerals absorbing CO₂ from the air. Their low-cost DAC solution is gaining attention for scalability.
6. Xero Technologies (India)
What they do: Energy-efficient cooling
With India facing rising temperatures, Xero is developing low-energy and zero-water air conditioning systems, solving for both power and water crises.
7. Pivot Bio (USA)
What they do: Biofertilizers
Pivot Bio replaces synthetic nitrogen fertilizers with microbes that feed plants naturally—reducing emissions and runoff in agriculture.
8. Ampd Energy (Hong Kong)
What they do: Electric construction site batteries
Ampd replaces diesel generators on construction sites with smart, emission-free battery systems—cleaning up one of the most overlooked sectors.
9. Notpla (UK)
What they do: Seaweed-based packaging
Notpla is developing biodegradable packaging from seaweed, offering an alternative to single-use plastics. Think edible water pods and compostable coatings.
10. Electric Hydrogen (USA)
What they do: Green hydrogen
Their modular electrolyzers make it possible to produce hydrogen without carbon emissions—potentially powering industries like steel and shipping.
