Climate Tech Funding Shifts: Early-Stage Investments Dry Up as Capital Concentrates in Established Players

Climate Tech Funding Faces a Critical Divide

When Donald Trump secured a second presidential term, the climate tech industry braced for uncertainty. His mixed rhetoric—praising electric vehicles while dismissing offshore wind as harmful to whales, and touting solar energy despite claims it harmed bunnies—was accompanied by a consistent energy mantra: "drill, baby, drill." Yet even as political winds shifted, key climate technologies continued advancing down the cost curve. This juxtaposition of policy hostility and technological progress is reshaping the funding landscape for climate innovation.

New reports from Sightline Climate, Silicon Valley Bank, and J.P. Morgan reveal a stark bifurcation in the industry. While well-capitalized investors and established climate tech firms secure record funding for large-scale projects, the venture ecosystem supporting early-stage solutions is struggling to keep pace.

Record Funding Masks a Troubling Trend

At first glance, the numbers appear impressive. Sightline Climate’s Dry Powder and New Funds report shows investors raised a record $92 billion in new climate-focused capital across 179 funds in the past year. However, 77% of this total was concentrated among the largest players—institutional heavyweights like Brookfield Asset Management, Copenhagen Infrastructure Partners, and Energy Capital Partners. These firms typically back proven technologies such as utility-scale solar, wind, and battery projects.

"A lot of infrastructure funds are very comfortable saying, Yeah, I’m going to do wind and solar. I know how that works. I can see the project finance there. All good."

Early-Stage Funding Plummets to Historic Lows

Meanwhile, the proportion of U.S. investment directed toward seed and Series A companies—critical for developing emerging technologies like carbon capture, green steel, low-carbon cement, and agricultural decarbonization—fell for the first time in nearly a decade. According to Silicon Valley Bank’s Future of Climate Tech report, this decline reflects a broader retreat from riskier early-stage ventures.

The share of total funding allocated to early-stage venture investors dropped from 20% in 2021 to under 8% in 2024, according to Sightline. This contraction stems from two key factors:

• Declining VC fundraising: The average fund size shrank from $174 million in 2024 to $160 million in 2025.
• Growing dominance of infrastructure investments: As the industry matures, larger-scale projects command a larger share of available capital.

Jordan Kanis, Managing Director of Climate Technology at Silicon Valley Bank, noted that while startup valuations are rising across all stages, the gains are uneven. "There’s clearly a story behind that where the top performers are doing really well and a lot of the longer tail are still scraping to keep up," he said. "There’s still money flowing into early-stage companies, but it’s more selective. The bar is higher."

Capital Concentration Deepens Within Early-Stage Ventures

Silicon Valley Bank’s data reveals that while headline valuations for startups are increasing from seed to Series C and beyond, the gains are skewed toward top-performing companies. The majority of early-stage ventures—particularly those working on high-risk, high-reward technologies—are finding it increasingly difficult to secure funding.

This selectivity reflects a broader trend in the climate tech sector, where investors are prioritizing proven models over untested innovations. The result is a funding ecosystem that increasingly favors established players, leaving critical early-stage technologies underfunded and at risk of stalling.

What’s Next for Climate Tech Funding?

The divergence in climate tech funding underscores a pivotal moment for the industry. As institutional investors double down on large-scale, low-risk projects, the future of early-stage innovation hangs in the balance. Without sustained support for emerging technologies, the industry risks leaving behind the very solutions needed to address the most pressing climate challenges.
