Climate Tech & Sustainability Flash Summary

1) Climate tech startups are regaining momentum

•Venture and growth funding in climate tech rose 8% in 2025 to $40.5 billion, after two years of decline.

•The market saw a record 179 climate fund closes, raising $92 billion in new capital.

•A major theme is the shift toward AI-enabled climate solutions: nearly 28% of climate equity dollars went to AI-related solutions, with data centers alone attracting nearly $2 billion.

2) Startup activity is concentrating in three areas

Trellis highlighted 15 startups to watch in 2026, clustered around:

•Data centers

•Materials / critical minerals

•Climate adaptation

Key drivers:

•Demand for domestic copper and lithium is rising, with projected deficits of 30–40% by 2035.

•Adaptation funding jumped 64%, as investors increasingly treat climate resilience as a financial risk category.

3) UK climate startup ecosystem shows strong deep-tech tilt

•Tech Nation unveiled 25 UK climate tech startups in its 2026 cohort.

•The cohort has raised $220M+ collectively, with an average of £9M per company.

•23 of 25 companies are building in hardware or life sciences, signaling a continued move toward deep-tech climate solutions.

•Cohort companies employ 370+ people, and 76% plan international expansion.

•Alumni across the program have raised £1.7B+ to date.

4) Clean energy innovation: storage, geothermal, and fuels

Recent startup examples highlighted in industry roundups include:

•Form Energy: announced a 300 MW / 30 GWh battery deployment with Xcel Energy for a Google data center in Minnesota — described as the largest battery energy storage system by energy capacity ever announced.

•Quaise: reached 118 meters of millimeter-wave drilling in granite, advancing a path to deep geothermal for clean baseload power.

•Twelve: its AirPlant One facility in Washington is slated to begin production in 2026, aiming to produce electrofuels at scale.

5) Policy and market signals

•Trellis noted that climate capital has “breached” after the U.S. federal government passed the One Big Beautiful Bill Act, which clarified the policy direction investors are responding to.

•The policy shift is being interpreted as a catalyst for renewed investment in climate tech, especially in AI infrastructure, domestic materials, and resilience.

•In parallel, J.P. Morgan’s 2026 Climate Tech Report points to continued interest in battery/grid technology and food/agriculture tech, with climate variability and supply-chain shocks increasing pressure on food systems.

6) ESG and sustainability investing outlook

•The latest data suggest ESG/climate investing is becoming more selective and more hardware-focused:

- More capital is flowing to infrastructure, physical climate solutions, and asset-backed adaptation
- Less emphasis on broad climate narratives; more on measurable deployment, commercial viability, and operational risk reduction

Bottom line

Climate tech is seeing a fresh funding rebound, with capital concentrating in AI-enabled infrastructure, clean energy storage, materials, and adaptation. The strongest signals today are:

•Rising startup funding

•Large-scale deployment announcements

•Policy-driven investor reallocation

•Growing interest in measurable carbon and resilience impact
