Climate technology is rapidly evolving, with new companies building solutions that tackle everything from carbon reduction to circular economies. The Trellis “25 Climate Tech Startups to Watch in 2025” list showcases some of the most promising players driving this innovation.
However, the recognition comes during a challenging moment. Climate tech investment totaled $13.2 billion in the first half of 2025, down 19 percent from the year before. With funding cooling, many founders are being pushed back to fundamentals by proving their economics, showing measurable impact, and delivering real customer value.
Of course, policy uncertainty has added to the headwinds. The Trump administration has rolled back many of the Inflation Reduction Act’s incentives, creating challenges for renewable energy and electrification. At the same time, new opportunities are emerging.
The AI and data center boom is also fueling demand for advanced energy solutions like nuclear, geothermal, and storage. Carbon capture is also gaining traction, with startups moving from pilot projects to commercial scale.
Against this backdrop, the Trellis list shows that climate entrepreneurs are pressing forward. Despite policy shifts and tighter capital, they are building the technologies that will define the next era of climate action.
