Greennex Pulse Exclusive: October Deal Spotlight

In September's climate tech dealflow, the U.S. market revealed a clear concentration around scalable, infrastructure-heavy plays — carbon offset platforms, EV charging hubs, geothermal baseload solutions, compact electric mobility, and carbon-negative building materials. These bets reflect where American investors are leaning: toward assets that can integrate quickly into existing supply chains and generate predictable cash flows, even under uncertain policy backdrops.

By contrast, the global stage painted a more diverse picture. Deals abroad ranged from sustainable aviation fuel in the U.K. to ship-cleaning robotics and refrigerated EVs in Singapore, AI agents for energy efficiency in Europe, and autonomous farm machinery in Australia. This mix underscores how international ecosystems are testing a broader array of models, often supported by stronger regulatory signals or targeted industrial demand.

Taken together, the September financings highlight an emerging duality: U.S. investors are anchoring capital into infrastructure-style climate assets, while global markets continue to serve as laboratories for diversified innovation. Both trends point to a maturing carbon-to-value landscape, where regional investment priorities reflect different paths to scaling climate impact.
