Climate Tech Watchlist Looms as 1.5°C Threshold Nears and AI Reshapes the Sector
RDU Global is preparing its 2026 list of Climate Tech Companies to Watch as the climate investment landscape enters a more urgent and more selective phase. The timing is stark: the United Nations says the planet is likely to pass 1.5°C of warming within the next few years, while political resistance in the United States continues to slow the policy response. Against that backdrop, frontier AI and machine learning are becoming central to climate technology, not as a cure-all but as a force multiplier for forecasting, grid management, industrial efficiency and carbon accounting. The companies most likely to matter in 2026 will be those that can turn climate pressure into measurable deployment, not just promising software.
