Counteract is a London-based venture firm focused almost entirely on carbon removal. While many climate funds mix efficiency, electrification, consumer brands, and occasional removal bets, Counteract specializes in technologies and tools that take greenhouse gases out of the atmosphere or lock them away for the long term. The first fund, Counteract One, is an early-stage vehicle (often described around £35 million / about $42 million) structured as an EU Article 9 strategy. It invests globally at pre-seed and seed, with a stated ambition to help catalyze on the order of 5 gigatonnes of CO2e removal potential by 2050. That framing matters: the firm is underwriting additionality and scale pathways, not only short-term offset demand. Portfolio work spans a wide removal stack. Direct air capture and mineralization sit alongside biomass pathways, ocean and coastal approaches, enhanced weathering, carbon-negative materials and fertilizers, and the measurement and verification software that keeps removal markets honest. The common thread is whether a solution expands durable removal capacity. For founders, Counteract is one of the clearest specialist VCs to approach when the product is removal-native. For LPs and ecosystem partners, it fills a gap between generalist climate VC and project finance that arrives too late for first-of-a-kind technology.

Extantia is a Berlin-based climate tech venture firm that backs pioneers reimagining industries. The firm invests in software and hardware with large, near-term market opportunities: companies that can make a cleaner path also the faster or cheaper path for customers. Founded in 2020, Extantia describes itself as a climate tech generalist rather than a single-vertical specialist. Energy, industrial processes, buildings, transportation, and carbon removal all sit inside the mandate when the commercial wedge is clear. The sweet spot is early stage, roughly seed to Series A, with a primary focus on European founders and team coverage across Germany and the UK. The firm closed its Extantia Climate Flagship II vehicle at about €204 million, above a €150 million target, with institutional LPs that have included the European Investment Fund, KfW Capital, and other European public and private investors. Extantia also built Extantia Ignite, an internal sustainability and science capability used for impact analysis, and has tied part of manager economics to sustainability targets. Beyond writing checks, Extantia markets itself as a long-term operating partner on commercialization, organization building, and fundraising. For founders evaluating European climate VCs, the combination of a sizable flagship fund, generalist sector scope, and an explicit science/ESG process is the main differentiator.

Future Planet Capital is an impact-led venture capital firm that backs innovative companies emerging from the world's top universities and research ecosystems.

Lowercarbon Capital is a venture capital firm that invests in companies developing technologies to combat climate change through three primary approaches: slashing CO2 emissions, removing carbon from the atmosphere, and buying time to address planetary climate issues. They focus on backing what they call "kickass companies" that can make real money while addressing environmental challenges across sectors including energy, transportation, industrial materials, and agriculture. The firm operates on the philosophy that fixing the planet is good business and that market forces, rather than shame and guilt, will drive the necessary climate solutions. They combine hard science with ambitious goals, seeking companies that can deliver better, faster, and cheaper alternatives to fossil fuel-based technologies. Lowercarbon Capital plays a significant role in the climate tech ecosystem by funding innovative companies across diverse sectors from solar and wind energy storage to fusion technology, electric aviation, and carbon-free chemical production.

Pale Blue Dot is a Malmö-based climate venture firm started by former founders who wanted a climate-only fund with operator empathy. The firm invests at pre-seed and seed in software and hardware companies building climate businesses across Europe and the United States. The investment map is intentionally simple. Optimize: technologies that decarbonize systems that already exist. Adapt: tools that help communities and industries live with climate impacts. Pioneer: breakthroughs that redefine what a sustainable future can look like. That structure helps founders place themselves quickly without forcing every company into a single vertical label. Typical checks are about €0.5 million to €2 million, and the firm often prefers to lead. Fund I closed around €87 million. Fund II closed around €93 million, putting combined fund capital near €180 million, with plans to back several dozen companies across the two vehicles. Coverage spans food and agriculture, industry, mobility, energy, fintech-for-climate, and related enabling software. Pale Blue Dot's public posture is practical rather than theatrical. Partners emphasize trust, hands-on support, and climate impact assessed before investment. For early-stage founders in Europe or the US who want a specialist climate lead without a mega-fund process, it remains one of the clearer Northern European options.

Pay it Forward Ventures (PIF) builds better lives for billions by investing in source-solving rather than symptom-solving. They fund and found ventures that create new paradigms across financial technology, health, energy, and digital infrastructure — and donate 20% of GP profits to philanthropy because they believe in paying it forward.

Prelude Ventures is a climate venture firm that invests across the technologies needed to rebuild a low-carbon economy. Climate is not a side sleeve. It is the whole mandate: built environment, carbon management, compute, energy, food and agriculture, manufacturing and industrials, and mobility. The firm screens for impact and invests for scale. In practice that means looking for category-defining companies that can create lasting climate benefit and still become large businesses. Prelude has been an early and consistent co-investor alongside other specialist climate funds, and it is comfortable across software, hardware, and deep technical work when the company can grow inside real markets. Public fund data has pointed to a large Climate Fund II vehicle (reported around $850 million), which places Prelude among the more capitalized dedicated climate VCs. Typical check sizes cited in market databases often land from about $100,000 to $5 million depending on stage and role, with the ability to stay involved as companies mature. For founders, Prelude is most relevant when the product sits in a hard climate category and needs a partner that already lives in those markets: grids and buildings, industrial processes, carbon removal and measurement, climate-relevant compute, or low-carbon mobility and food systems.

Prosper Global Ventures is the early-stage impact investing and venture-building platform of Prosper Global, the global development organization formerly known as Mercy Corps. The platform was founded in 2015 as Mercy Corps Ventures and now operates as a family of funds backing founders whose technologies help people and markets withstand climate and economic disruption. Its Resilient Future Thesis is organized around three connected areas: adaptive agriculture and food systems, inclusive climate fintech, and climate-smart technologies. The team invests primarily across Sub-Saharan Africa and Latin America, prioritizing founders who understand the communities they serve and businesses that can scale across a region or globally. Earlier Fund I activity also included Southeast Asia. Prosper Global’s current Ventures page reports 61 early-stage companies supported, $753 million in follow-on capital catalyzed, and 46.3 million customers reached across 90 countries. Its 2025 impact report says 83% of portfolio companies had raised follow-on capital and 46% had at least one woman co-founder. These are Prosper Global Ventures’ reported portfolio figures, not independent impact measurements. The platform combines equity investment with pilots, technical assistance, impact measurement, partnerships, and post-investment support. Representative investments made under the Mercy Corps Ventures name include Pula, which provides agricultural insurance and advisory products for smallholder farmers; Floodbase, which develops flood-risk data and analysis; Wasoko, a last-mile commerce and financing platform for small retailers; AgriAku, an agricultural input marketplace; Ejara, an inclusive savings and investment platform; and Verqor, an agri-fintech platform serving farmers in Mexico. Prosper Global Ventures is embedded within Prosper Global’s humanitarian and development network, giving portfolio companies potential pathways to test products with communities affected by climate volatility, financial exclusion, fragile food systems, and infrastructure gaps. The venture platform is associated with Scott Onder, its co-founder and senior investment leader, while Tjada D’Oyen McKenna leads the parent organization as CEO.

With over $1.5 billion in AUM and a portfolio exceeding 1,000 companies across more than 70 countries, SOSV occupies a distinctive position in the venture landscape: a programmatic investor that takes companies from idea stage through to growth and beyond. The firm's accelerator model means it is often the first institutional check into a company, with follow-on capability through later rounds. SOSV has a strong impact orientation across its portfolio, with climate, food systems, health, and sustainability representing a significant share of its investments. Its programs in particular have become known as launchpads for companies working on hard scientific and engineering problems that require more than capital to succeed.

SustainVC is an impact-focused venture capital firm that backs innovative entrepreneurs working toward a sustainable, more equitable, and healthier world. The firm focuses on two primary impact areas: Climate & Sustainability, and Access & Opportunity, targeting companies that can deliver both positive impact and positive returns. Their mission centers on supporting entrepreneurs who share their vision of creating systemic change through market-driven solutions. SustainVC operates with the philosophy that profitable investments and meaningful impact can go hand in hand, seeking to accelerate positive change through strategic capital deployment.

World Fund is a European climate tech venture firm that backs founders building the technologies Europe needs to compete and to cut emissions at industrial scale. The firm is based in Berlin, with a wider footprint across Munich, Cologne, and Amsterdam, and it concentrates on deep tech in energy, industry, and food and agriculture. Unlike broad climate funds that stretch from consumer brands to carbon software, World Fund is explicit about hard technology and measurable decarbonization. Every opportunity is assessed through a Climate Performance Potential lens: can this product cut meaningful emissions if it scales, and can it win commercially in a real market? That framing is meant to keep climate impact and financial performance on the same page, not in separate decks. The founding partners include Daria Saharova, Danijel Višević, Tim Schumacher, and Craig Douglas. The first fund closed around €300 million, reported as one of the largest debut climate VC funds in Europe, with room for roughly 25 to 30 core investments and substantial follow-on capital. The team has been public about reserving a large share of the fund for later rounds, because European climate companies often struggle to bridge the Series B gap. Portfolio companies sit in the physical economy as much as in software. Examples that show the range include battery recycling (Cylib), industrial and building energy (Enerkii, aedifion, ecoworks), alternative proteins and food tech (Planet A Foods, Juicy Marbles, ENOUGH), and deep tech such as IQM Quantum Computers and Space Forge. For founders, the useful signal is simple: World Fund wants durable technology businesses with climate math that survives scrutiny.
