Climate Tech Startups & Funding

•Global investment in climate tech startups has cooled in 2025, with early- and growth-stage funding totaling $13.2 billion in the first half of the year—a 19% drop from the previous year[3]. Despite this, entrepreneurs remain resilient, focusing on proving unit economics and customer value as the bar for traction rises[3].

•A new $300 million “valley of death” fund, the All Aboard Coalition, aims to bridge the gap between early-stage funding and the $100–200 million rounds needed for first-of-a-kind climate projects[1]. Led by Chris Anderson (former TED curator), the coalition includes top-tier climate investors like Breakthrough Energy Ventures, Khosla Ventures, and Energy Impact Partners[1]. The fund will provide equity or convertible equity, not loans, signaling confidence to larger institutional investors[1].

•Notable startups include Avalanche Energy (micro-fusion reactors, $114.3M raised), Solugen (plant-based chemicals, $138.2M), and Geltor (cellular agriculture proteins, $474.1M)[5]. European standout 1KOMMA5° recently secured €150 million in pre-IPO funding to expand its energy management software[9].

•Y Combinator and other accelerators continue to back climate tech, with 49 climate startups currently in YC’s portfolio[7]. OpenVC’s updated database lists active climate tech investors, emphasizing that serious funds now prioritize startups with real IP, infrastructure, or regulatory traction[4].

Clean Energy & Carbon Impact

•Nuclear, geothermal, and energy storage are gaining traction, buoyed by demand from AI and data centers[3]. Carbon capture is entering the mainstream, with several startups achieving both investment and commercial milestones[3].

•Carbon Analytics offers a SaaS platform to measure and reduce supply chain emissions, having raised $5 million[5]. Deep Sky focuses on scalable CO₂ removal[6].

•Global climate tech unicorns (valued at $1B+) now number 80, with a collective valuation exceeding $180 billion as of early 2023[8]. While not all are pure clean energy plays, many are driving material carbon reductions in energy, transport, and industry.

ESG Investing Trends

•ESG investing remains active but selective, with climate tech now seen as a cross-sector opportunity (energy, SaaS, agriculture, fintech, mobility, manufacturing)[4]. Corporate climate targets are now standard in quarterly reports, and regulators globally are increasing green incentives[4].

•The “missing middle” in climate tech finance—between seed and growth capital—is a critical bottleneck, especially for hardware-heavy solutions[1]. The All Aboard Coalition is a direct response to this gap, aiming to de-risk later-stage investments for institutional players[1].

Climate Policy & Regulatory Shifts

•U.S. policy headwinds: The Trump administration has rolled back many Inflation Reduction Act (IRA) incentives, creating challenges for renewable energy and electrification startups[3]. However, some federal support remains, and startups are increasingly turning to corporate partners, philanthropy, and alternative loans to fill the gap[2].

•International momentum: The EU Green Deal and APAC net-zero initiatives continue to drive investment and innovation, with regulators writing “bigger checks” for climate solutions[4].

•Local innovation hubs, such as ClimateHaven in New Haven, are helping startups access mentorship, industry partners, and funding, keeping talent and innovation close to academic centers like Yale[2].

Environmental Innovations

•Cellular agriculture (e.g., Mosa Meat, Integriculture) and plant-based proteins (Seattle Food Tech) are reducing the carbon footprint of food production[5].
