10 Leading Companies in Climate Technology

With only 25 years remaining until the net zero deadline, climate technology is swiftly evolving from a speculative field into a vital and integral component of the global economy.

As we approach COP30 this November, the industry is demonstrating both its resilience and determination in the face of changing capital flows and geopolitical uncertainty.

The climate tech market is expected to grow from US$32.49bn in 2025 to US$79.45bn by 2029, clearly reflecting the confidence investors have in the sector’s long-term sustainability.

While this year has witnessed significant advancements in the maturation of climate tech, it has also been marked by the rapid ascent of AI.

AI serves as an ally to many climate tech innovators, but it also poses challenges to the global climate action mission in various ways.

This presents a compelling paradox. While AI can provide governments and executives with tools to optimize energy grids and industrial processes, its enormous demand for electricity and water is exerting unprecedented pressure on Earth’s resources and climate, with a single Gen AI query consuming nearly ten times the energy of a standard web search.

This challenge, however, is also driving a wave of innovation, channeling investment into grid modernization, long-duration energy storage, and sustainable data centers.

But which companies are excelling in turning a potential crisis into a powerful catalyst for climate solutions?

In this week’s Top 10, we highlight some of the sector’s most promising and accomplished players.
