1. Funding Trends: AI vs Climate Tech in 2025
AI Takes the Lion’s Share
In the first half of 2025, U.S. and Canadian startups attracted around $162.8 billion in venture funding. A staggering 64.1% of this deal value was AI-related. That means almost two-thirds of all startup dollars are flowing directly into AI. (Reuters)
This surge is largely due to:
- The rise of generative AI platforms and foundation models.
- AI applications across healthcare, finance, logistics, and education.
- Investor appetite for high-margin, software-first businesses.
Climate Tech: Growing, but Uneven
Climate tech funding hasn’t disappeared—it’s evolving. According to SVB’s Future of Climate Tech report, U.S. clean energy and power companies raised $7.6 billion in 2024, a 15% year-over-year increase. (SVB)
However, 2025 has shown mixed results:
- Mature sectors like solar and batteries have seen a dip.
- Emerging areas like carbon capture, hydrogen, and climate adaptation are gaining more traction.
The AI + Climate Tech Intersection
Here’s the kicker: climate startups using AI are booming. PwC found that AI-driven climate startups raised $6 billion in the first three quarters of 2024, already outpacing 2023 totals.
NetZero Insights adds that 1 in 5 climate tech dollars now go to AI-enabled solutions, with this sub-sector growing at 8.77% CAGR (2020-2024) compared to 7.76% for broader climate tech.
2. Which Sector Commands More Focus?
- AI dominates in absolute funding, deal volume, and public buzz.
- Climate tech holds steady, supported by regulation and ESG priorities.
- Hybrid AI + climate solutions are carving a new lane—these are increasingly attractive to investors because they combine impact with scalability.
3. Real-Life Startup Examples
| Startup | Focus | What They Do | Why It Matters |
|---|---|---|---|
| Climatiq | AI + Climate Tech | Automates Scope 3 carbon data collection using AI. Raised $11.6M Series A in 2025. | Tackles one of the hardest parts of climate reporting. |
| Remora | Climate Tech | YC-backed carbon capture for trucks. | Shows investor belief in hardware-heavy solutions despite slower scale. |
| Grid AI Platforms | AI + Climate Tech | Optimize renewable energy grids, forecast demand, manage storage. | Bridges the gap between clean energy and AI. |
| Pure AI Startups | AI | Build foundation models, workflow automation tools, etc. | Scale quickly and attract big rounds due to software focus. |
These examples highlight why AI scales faster, but also how AI is making climate tech more fundable.
4. How Geography and Policy Shape Focus
- United States leads in both AI and AI-enabled climate funding. Nearly 90% of North American AI-enabled climate tech investment happens in the U.S.
- Policies like the Inflation Reduction Act (IRA) have spurred billions in clean energy and infrastructure investments.
- Europe, while strong in policy, has seen climate tech equity investment cool in early 2025.
5. Pain Points Holding Back Each Sector
Climate Tech Challenges
- Capital-intensive and slower to scale.
- Regulatory hurdles and long permitting processes.
- Heavy dependence on subsidies and carbon pricing.
- Complex data measurement (e.g., Scope 3 emissions).
- Long ROI timelines compared to software.
AI Challenges
- Fierce competition and commoditization.
- Regulatory risks around data privacy and safety.
- Expensive compute and GPU infrastructure.
- Short product lifecycles, leading to fast obsolescence.
6. What Americans Prioritize in 2025
