Episode 16: Federico Cristoforoni (Net Zero Insights) - The State of Climate Tech in 2025

Episode summary

Federico Cristoforoni, Co-Founder and Managing Partner of Net Zero Insights, discusses the findings of the State of Climate Tech 2025 report on Episode 16 of Scaling Green Tech, a podcast by Adopter.

Cristoforoni traces the shift in climate tech investment from the hype-driven environment of 2021-2022 to the selectivity-driven market of 2025. Total funding levels have stabilised since a 2023 collapse, but the number of transactions dropped sharply - meaning fewer companies are getting funded, each clearing a higher bar. Graduation rates tell the sharper story: 50% fewer companies are progressing from seed to Series A, and 80% fewer are making it from Series A to Series B compared to 2022. For hard-tech companies, the centre of gravity has shifted from prototype stage in 2022 to demonstration stage in 2025, signalling that technologies are proving they work but now face the second valley of death around commercial scaling. The report also finds that 25% of climate tech investment in 2025 went to companies using AI as a core part of their value proposition. Adaptation's share of total funding has doubled to 8% over five years. And India has overtaken the UK as the second-largest market for climate tech investment by volume.

This episode is relevant for climate tech founders preparing fundraising strategies in a tighter market and venture capital investors benchmarking portfolio performance against sector-wide data. It is also useful for corporate innovation teams tracking technology readiness across climate verticals, and B2B marketers positioning climate solutions around cost and performance rather than impact language.

Key takeaways

  • 50% fewer companies are progressing from seed to Series A in 2025 compared to 2022, and 80% fewer are making it from Series A to Series B. Cristoforoni frames this as the market shifting from hype to fundamentals. Investors now require commercial traction and proof of market demand, not just technical validation.
  • Total climate tech funding levels have stabilised since the 2023 collapse, but the number of transactions dropped sharply in 2025. Fewer companies are getting funded. Those that do raise capital are clearing a higher bar - a dynamic Cristoforoni frames as investor selectivity rather than market retreat.
  • 25% of climate tech investment in 2025 went to companies using AI as a core component of their value proposition. Applications span grid optimisation, energy flexibility, material discovery, and process efficiency. Cristoforoni distinguishes between AI as a general operational tool and AI meaningfully integrated into a company's core offering.
  • Adaptation's share of total climate tech funding has doubled from approximately 4% to 8% over the past five years, growing consistently even as other segments fluctuated. Cristoforoni attributes this to adaptation's alignment with the broader market focus on resilience.
  • The centre of gravity for hard-tech climate companies has shifted from prototype stage in 2022 to demonstration stage in 2025. The majority have proved their technology works but now face the second valley of death - the gap between technical validation and commercial-scale market adoption.
  • India has overtaken the UK as the second-largest market for climate tech investment by volume, more than doubling its investment level year on year. The US remains first by a significant margin, with a 7.5% increase year on year despite policy rollbacks under the new administration. China appears fifth in the data, though Cristoforoni notes this likely understates its actual position due to limited disclosure.
  • Government grants are retreating from the earliest stages of breakthrough innovation, particularly in the US. The report already shows a decrease in companies at the R&D phase (TRL-3). Cristoforoni expects this pipeline contraction to become more visible over the next one to three years.
