Top Private Equity Firms in Climate Tech
Climate tech has grown from a niche category into one of the most actively funded sectors in private markets. US climate tech venture and private equity investment reached $29 billion in 2025, the third-highest annual total on record, and the asset class now accounts for more than 10 percent of all private equity and venture capital deployment globally. That scale has attracted a wide range of investors, from early-stage backers writing $55,000 checks to institutional funds managing billions across infrastructure, industrial technology, and energy transition.
The directory above lists every private equity firm PEL tracks with a climate tech mandate, filterable by geography, stage, and check size. The entries below give you the context the filters cannot: what each firm actually does, how it is structured, and which type of founder or co-investor is most likely to find it relevant.
1. 8090 Industries
Founded in 2022 by Kerem Ozmen and Rayyan Islam, 8090 Industries is one of the newer entrants on this list. Despite a short operating history, the firm has moved quickly, building a tracked portfolio of more than 26 investments across 25 companies. The focus is early-stage industrial technology, a segment that sits at the intersection of manufacturing, software, and the energy transition.
The firm reports total assets under management (AUM, meaning the total capital it oversees on behalf of investors) of approximately $1.38 billion as of August 2026. That figure is split between $775 million in primary discretionary advisory assets and $607 million in other assets. A separate filing cites roughly $200 million AUM, which may reflect only the direct fund vehicle rather than the full advisory platform.
For founders building early-stage companies in industrial or manufacturing technology with a climate or efficiency angle, 8090 Industries is one of the few PE-oriented firms operating at this stage and sector combination. Its recency means track record is still forming, but the pace of 26 investments in under three years signals active deployment.
2. ADM Capital
ADM Capital was founded in 1998 and has spent more than two decades financing mid-market companies across the Asia-Pacific region that larger banks have historically overlooked. Its primary instrument is private credit, meaning it lends to businesses rather than taking equity stakes in the way a traditional buyout fund does. Typical investment sizes run from $20 million to $50 million per transaction.
Since pivoting its Asia funds toward sustainability-linked mandates in the early 2000s, the firm has invested in more than 170 companies. It is headquartered in Hong Kong and reports AUM of approximately $1.6 billion, with some sources citing a higher figure closer to $3.4 billion depending on how affiliated vehicles are counted.
For companies in Asia-Pacific that need growth capital or structured debt rather than equity, and that sit in sectors relevant to climate resilience or environmental standards, ADM Capital is worth understanding. Its check-size floor of $20 million means it is not a fit for seed or early-stage businesses, and its credit-first approach suits companies with existing revenue and asset bases rather than pre-revenue ventures.
3. Africa Finance Corporation
Africa Finance Corporation (AFC) is not a traditional private equity fund. Founded in 2007 as a joint venture between public and private investors and structured as an international organization under treaty, it operates more like a development finance institution with a mandate specific to African infrastructure. Its total disbursements have exceeded $19 billion since inception.
The climate dimension is direct and large. The Green Climate Fund committed a record $253 million to AFC's Infrastructure Climate Resilient Fund for Africa, a vehicle with a target size of $750 million. AFC has also approved up to $100 million to invest in Africa-focused technology fund managers as part of an effort to accelerate digital industrialization across the continent. Its investment portfolio is valued at approximately $2 billion.
For fund managers and project developers working on climate-resilient infrastructure in Africa, AFC is a rare source of patient, large-scale capital with both public legitimacy and private market discipline. It is not the right door for individual startups seeking early equity, but it is highly relevant for infrastructure sponsors, co-investors, and fund managers looking for an anchor LP (a lead investor who commits capital to a fund and often helps attract others) with continent-specific expertise.
4. Alder
Alder is a Stockholm-based Nordic private equity fund focused on acquiring and growing technology companies in the region. Founded in 2008, it has raised 8.4 billion Swedish kronor since inception across two fund vehicles. Alder Fund I, established in 2010, invested in nine companies and closed in 2025. Alder Fund II, established in 2018, is described as fully invested.
The firm's climate tech relevance comes through its sector focus rather than an explicit sustainability mandate. Technology-enabled industrial companies in the Nordic region frequently operate in energy, resource efficiency, and cleantech-adjacent markets, and Alder's buy-and-build approach suits businesses at the growth and buyout stage rather than venture.
With both current funds now either closed or fully deployed, the immediate question for any founder or co-investor is whether a third fund is in formation. For those building or operating Nordic technology businesses with a climate or industrial efficiency angle, Alder's track record across two fund cycles and its regional concentration make it a firm to monitor rather than approach cold at this moment.
5. Amundi Private Equity Funds
Amundi Private Equity Funds is the direct private equity arm of Amundi, a Paris-headquartered asset manager with approximately 2.38 trillion euros in AUM as of 2025, making it one of the largest asset managers in Europe. The private equity unit focuses on growth capital and buyout transactions in the range of 20 to 60 million euros per deal.
Founded in 2010, the firm manages approximately $2.4 billion in its private equity vehicles. An earlier benchmark from 2009 shows 3.7 billion euros committed by French and international subscribers, indicating the platform has been actively deployed across multiple cycles.
The parent institution's scale matters here. Amundi's infrastructure and ESG (environmental, social, and governance) integration capabilities give its private equity deals access to resources most standalone PE funds cannot match. For European companies in the growth to buyout stage seeking a partner with institutional depth and sustainability reporting requirements built in, Amundi Private Equity Funds occupies a distinct position on this list.
6. Antler
Antler is one of the most active early-stage investors in the world by deal count. Since its founding in Singapore in 2017, it has made more than 1,900 investments into early-stage startups across multiple geographies. Its AUM stands at approximately $1 billion as of 2024.
The firm's model is built around identifying and backing founders at the earliest possible moment, often before a company has a product or even a full team. Climate tech is one of several sectors Antler invests across, rather than a singular mandate. That breadth is both a feature and a limitation: founders get access to a global network and a rapid investment process, but climate-specific domain expertise is spread across a wide portfolio.
For first-time founders building a climate tech business who are at the idea or pre-product stage and are based in or willing to relocate to one of Antler's program cities, the firm's volume and speed make it one of the more accessible entry points on this list. The tradeoff is check size, which at the pre-seed level is small, and the cohort-based structure requires founders to go through a defined program rather than a traditional pitch process.
7. Argos Soditic
With roots going back to 1989, Argos Soditic is one of the oldest firms on this list. Over 35 years it has worked with more than 100 businesses, primarily in Europe, across B2B, B2C, and, more recently, climate action sectors. The firm manages approximately 2.5 billion euros in AUM and writes checks between 15 million and 100 million euros per deal.
The climate dimension is housed in a dedicated vehicle called the Argos Climate Action fund, which separates it from climate-integrated generalist funds on this list. That structural choice signals a deliberate institutional commitment rather than a thematic overlay applied to existing portfolios.
The combination of a 35-year track record, a dedicated climate fund, and a 15 to 100 million euro check range makes Argos Soditic a strong candidate for established European businesses at the growth or buyout stage looking for a partner with both longevity and explicit climate credentials. Pre-revenue or seed-stage companies fall well outside the check-size floor.
Let's Recap
The firms on this list span a wider range than the label "climate tech private equity" might suggest. At one end you have early-stage investors like 8090 Industries and Antler writing checks that start in the tens of thousands and targeting companies that may have little more than a founding team and a prototype. At the other end are institutional platforms like Amundi Private Equity Funds and Argos Soditic deploying 20 to 100 million euros per deal into established European businesses with revenue, assets, and operating history. Africa Finance Corporation sits in a category of its own, structured more like a development finance institution than a traditional fund, relevant primarily to infrastructure sponsors and fund managers rather than individual companies.
Geography is the other major dividing line. ADM Capital and Antler are built around Asia-Pacific and global deployment respectively. Alder concentrates almost entirely on the Nordic region. AFC's mandate is Africa-specific. Argos Soditic and Amundi Private Equity Funds are European-focused. 8090 Industries operates primarily in the US industrial technology market. Matching your geography to the firm's mandate is at least as important as matching your stage or sector.
For practical targeting:
- Pre-seed or idea-stage climate tech founders: Antler
