    The Rise of Climate Tech Startups and How They’re Attracting Investment

    by | Jun 16, 2025 | Sustainability & Impact Investing

    As climate change accelerates, entrepreneurs and investors alike are focusing their attention on climate tech—startups that aim to reduce emissions, mitigate climate risks, and accelerate the transition to a greener economy. The climate tech ecosystem has seen record-breaking funding rounds, government backing, and cross-industry collaboration. According to PwC, investment in climate tech exceeded $87.5 billion globally in the first half of 2023 alone .

    This article explores what’s fueling the climate tech boom, the types of technologies driving change, notable startups, and what investors should consider before jumping in.

    What Is Climate Tech?

    Climate tech refers to startups or technologies designed to combat climate change. It spans industries and can include:

    • Renewable energy innovations (solar, wind, tidal)

    • Carbon capture and storage

    • Electric mobility and transportation

    • Foodtech and sustainable agriculture

    • Energy storage

    • Water conservation

    • Sustainable materials

    These ventures aren’t just about ethics—they’re becoming economically competitive and investor-ready.

    Why Investors Are Flooding Into Climate Tech

    1. Massive Market Potential

    The global climate economy is forecast to reach over $9 trillion by 2030 . Startups tapping into decarbonization and sustainability benefit from long-term macro trends like energy transition, food security, and supply chain resilience.

    2. Policy and Regulatory Tailwinds

    The U.S. Inflation Reduction Act (IRA), EU Green Deal, and other international initiatives are funneling billions into clean energy infrastructure and tax credits for green innovation.

    3. ESG and LP Pressure

    Institutional investors are requiring ESG-friendly portfolios. As a result, VCs are building climate-focused funds or allocating larger shares of generalist funds to green tech.

    Top Climate Tech Startup Examples

    1. Climeworks (Switzerland) – Specializes in direct air carbon capture. Raised $650M in 2022.

    2. Charm Industrial (USA) – Converts biomass into bio-oil for underground carbon storage.

    3. Meati Foods (USA) – Mushroom-root-based meat alternative gaining traction in alternative protein space.

    4. Twelve (USA) – Converts CO2 into industrial chemicals and fuels.

    5. Carbon Clean (UK/India) – Offers carbon capture tech for industrial use cases, raising over $150M.

    Investment Hotspots

    • Europe: Particularly strong in cleantech (e.g., Netherlands, Germany, Nordics)

    • United States: IRA and Silicon Valley driving green innovation

    • India & Southeast Asia: Rapidly growing climate-focused agtech and energy startups

    • Africa: Microgrid, clean cookstove, and water purification innovations getting traction

    Challenges Climate Tech Startups Face

    • Hardware Complexity: Many climate solutions aren’t software-based, requiring high CapEx and longer timelines.

    • Commercialization: Bridging the “valley of death” between pilot projects and market scale remains tough.

    • Regulatory Barriers: Navigating environmental permitting, energy regulations, and compliance can delay deployment.

    Despite these hurdles, many investors are taking a long-view approach, seeing these as necessary hurdles for world-changing innovation.

    How to Evaluate a Climate Tech Investment

    1. Technology Readiness Level (TRL) – Is it a concept, pilot, or scalable solution?

    2. Unit Economics – Can it compete with incumbent alternatives?

    3. Policy Fit – Does it align with current and upcoming regulatory support?

    4. Team Experience – Founders with deep technical and industry knowledge are key.

    5. Impact Metrics – CO2 abatement potential per dollar is becoming a benchmark.

    Conclusion

    Climate tech isn’t just a moral imperative—it’s a booming sector with immense financial upside. For startups, aligning innovation with sustainability gives them a long runway. For investors, supporting climate solutions means betting on a resilient, scalable future.
