🌎 Who are the climate tech VCs?

CTVC’s 2023 investor list refresh (and reframing)


The market may be freezing over, but the world is still warming. There’s never been a better time to be a climate entrepreneur—just see the influx of incentives, spiking spend, technology traction, and a torrent of talent. As the tourist investors retreat to more familiar waters, now’s the time for climate-first investors to lean into the current.

Over the past three and a half years, we’ve obsessively tracked every dollar invested in early stage climate—and who’s behind those checks—to aggregate the most comprehensive and accurate response to our newsletter namesake: “Who are the climate tech VCs?”

In early 2020, it was easy enough to point to the surviving group of clean tech 1.0 veterans and so-called impact investors. Then the party started growing as ESG-earmarked LP capital buoyed existing managers’ balances and new funds erupted from old firms. Tried-and-true deeptech dollars and sector specialist savvy followed. Over the past 18 months, a bevy of new firms led by climate-first managers launched—from proper institutional vehicles, to solo GPs and rolling funds, to those anchored by a single family or foundation or corporate. And just in time, because as the jubilee of the bull market fades alongside the sky-high valuations, it’s time to do the strenuous work that’s rooted in real customer demand, deep value chain understanding, and science, not storytelling.

This week, we’re sharing our definitive list of climate tech VCs, updated for 2023. We created this list for the builders, who can filter it to their fancy on our website—by size, geography, and strategy. As climate tech moves from early innovation to the challenges of deployment, we're also broadening our focus to include investors beyond venture and putting out a call for reader input on an expanded climate capital stack list (more on that below).

Directory of funds putting climate first

The list and methodology below are updated for 2023, but the included funds remain the most active supporters of climate tech deals, quantitatively speaking. There is no popularity contest, buying a slot, or marketing manipulation. We’ve spent the time trawling through each VC’s performance so that the founders need not—and can get back to building.

The latest on climate tech VCs

In 2022, more than 4,000 unique investors participated in at least one climate deal, with about half investing in >1 deal. Just a fraction of those—198 VCs—made this list of the core group of firms actively investing in climate tech theses. That number is up from 177 VCs that fit the criteria a year ago.

Based on our deal-tracking database, this list includes VC firms that have invested in climate companies since the end of 2021. With the aim of pointing founders to the investors who can help them build, we weighted climate-specific deals as a proportion of total fund size.

We categorize funds according to four strategies

  • Climate: climate general thesis across 7 climate verticals (e.g. energy, mobility, food & ag, industrials, built enviro, climate intelligence, carbon)
  • Vertical specialist: single vertical focus within climate (e.g. energy, mobility etc.)
  • Deeptech: frontier, hard science technologies to address climate
  • Generalist: predominantly enterprise or consumer software, with opportunistic climate investments

We reviewed the existing list, submissions from VC firms, investors in our deals data, and new climate funds from our dry powder analysis and included only the VCs actively investing in climate tech in this update.


  • Must have participated in >1 climate deal since the end of 2021
  • Meet minimum threshold of climate companies as a % of overall portfolio, approximate by fund category (Climate: 75%, Vertical specialist: 75%, Deeptech: 25%, Generalist: 10%)
  • Included only institutional venture capital structures (e.g. excluded Private Equity, Foundations, Venture Debt, Project Finance, etc.)
  • Excluded microfunds with AUM <$10m
  • Excluded corporate VCs

Expanding the Climate Capital Stack (beyond venture capital)

VC may be in our name, but as climate tech zooms out from early VC-backed innovation to the critical growth phases of deployment and scaling, we’re also broadening our focus.

Many founders have found initial traction and are now seeking non-dilutive capital that can help them deploy. But it’s more difficult to secure investments in today’s macroeconomic environment, and climate tech founders facing the challenge of building physical assets and infrastructure need to consider all available sources of funding. It’s precisely this important scale-up capital that can be the hardest to find.

So as the climate tech capital stack itself innovates, so are we. We’re expanding our list to include other types of capital allocators to our catalog of investors.

This isn’t yet a comprehensive climate tech capital stack, just a representative sample of institutional asset classes needed to finance climate tech to scale. The investors named here are a reference point for the types of capital allocators we’re adding to the list.

In the future, we’ll build this list out further to include crucial parts of the capital stack, particularly the early catalytic side, like accelerators, nonprofits/NGOs, governments (DOE), and catalytic capital.

We’ve endeavored to be comprehensive and transparent in open-sourcing this list as a public good, but—of course—we’re bound to have missed something! Please do share with us if your fund’s profile needs a tweak, we missed a fund altogether (triple check the criteria first 🙏), or you’re allocating climate capital outside the realm of venture.

Other feedback? Musings? Favorite emojis? Reach out, we’d love to hear from you! As our venture namesake brethren like to say… let us know how we can be helpful 😉.
