Climate Tech Investors Are Digging This Beat | Clean Up Marketing

PitchBook just brought in an entire percussion section.

I've written repeatedly that no one is funding climate change. Investors fund companies. Customers buy products. And both groups have problems that are usually more immediate than the parts per million of carbon dioxide in the atmosphere.

Lower my electric bill. Give me a reliable source of power. Reduce my dependence on a fragile overseas supply chain. Turn my waste into something valuable. Replace a chemical that's getting harder or more expensive to use. Help me manufacture something domestically that I've been importing from the other side of the world.

PitchBook's Q2 2026 Climate Tech Report puts some very large dollar signs behind that argument.

Climate tech overall investment is on pace for its strongest year since 2022. Investors put $29.2 billion into 1,087 deals during the first half of 2026, which puts the industry on pace for approximately $58.4 billion for the year.

That's the number likely to generate the headlines. The other number should get the attention of anyone currently trying to raise money.

At the current pace, there will be approximately 2,174 climate tech deals this year. You have to go back to the pandemic year of 2020 to find a year with fewer deals.

More money is flowing into climate tech while fewer companies are getting it.

For the typical U.S. climate tech founder raising a Seed, Series A or Series B round, $58.4 billion of projected investment doesn't mean there are $58.4 billion worth of opportunities. Investors are becoming more selective about where they place their bets.

And PitchBook tells us something about the case investors find compelling.

If you’ve been following the news for the last 18 months, you know the term ‘decarbonization’ is out of vogue in the halls of power. There’s been a corresponding shift away from decarbonization as the primary investment driver and toward resilience, energy independence and economic benefits. 

AI/data centers are creating an enormous new economic need. That need is pulling investment toward technologies that can produce power, store power, manage power and use power more efficiently. Resilience and energy independence aren't floating investor preferences. They have a major demand driver behind them.

Investors are voting on those messages with their money.

That doesn't mean climate has disappeared from the equation. I think we've reached the point where sophisticated climate tech investors already understand that technologies that improve energy efficiency, reduce waste, recycle or reuse materials, replace harmful chemicals, create new sources of energy and shorten supply chains are probably going to produce a climate benefit. (Read: You don't have to spend the first three slides of your investor deck explaining climate benefits.)

If your technology cuts the amount of electricity required for an industrial process by 30 percent, the investor can figure out that using less electricity probably reduces emissions. If you recover a valuable material from a waste stream, you don't need to explain that recycling it is preferable to throwing it into a landfill and mining or manufacturing more of it. If you're producing a critical material domestically that currently travels halfway around the world, the climate benefit isn't particularly difficult to spot.

What the investor still needs you to explain is why anybody will pay for it.

That's where message discipline matters, particularly when the number of companies receiving checks is shrinking. Every minute you spend explaining something your audience already understands is a minute you're not spending on the business problem that makes your technology necessary. The people sitting across the table need to understand whose electric bill gets smaller, whose supply chain gets shorter, whose production line becomes more reliable, whose waste becomes valuable, or whose dependence on an increasingly expensive material disappears.

The same discipline applies when you leave the investor meeting and walk into a customer's office. Your customer may care deeply about sustainability. Their company may have a net-zero commitment splashed across its annual report. But someone still has to justify the purchase internally, and lower costs, reliable operations, secure supplies and reduced risk tend to survive the trip from the sustainability office to the CFO's desk.

None of this requires climate tech founders to hide their mission. Most of you started these companies precisely because you saw an enormous environmental problem worth spending a substantial portion of your life trying to solve. That conviction belongs in your story. It tells investors something important about why you're willing to endure the years of R&D, fundraising, pilots, permitting and commercialization required to bring hard technology into the world.

Message discipline requires understanding that the person across the table has a different job. An investor has to decide whether your company can become valuable. Your customer has to decide whether your technology solves a problem worth the cost and risk of adopting it. They already know they're sitting in a climate tech meeting.

Make your percussion section hit a constant beat of the problem you solve for them.
