Key Information

6. Challenges in the US Market

• Tariffs: The US's unpredictable tariff policies have created uncertainty, especially for hardware-intensive sectors like built environment and industrial decarbonization.
• Policy Uncertainty: The potential repeal of Biden-era clean technology support, including the 45Q tax credit for carbon capture, poses risks to VC-backed projects.
• DAC Hubs: The Department of Energy's review of funding for DAC hubs in Louisiana and South Texas may affect companies like Climeworks and Carbon Engineering.

7. EU Trends

• ETS2: The EU is preparing to implement a second Emissions Trading System (ETS2), covering emissions from the built environment and road transportation.
• Carbon Allowances: Continued reduction of carbon allowances under the first ETS is incentivizing decarbonization across industries.

8. Segment-Specific Trends

• Built Environment: Led by large early-stage funding rounds for Reno and Elvy.
• Industry: Dominates VC deal value with a focus on low-carbon manufacturing, green mining, and circular economy technologies.
• Land Use: Includes soil pollution remediation, which is a smaller category with an average of $17.2 million in annual deal value.

Summary of VC Deal Value by Stage

• Median Deal Value: Varies by stage, with higher values observed in later-stage deals.
• Pre-Money Valuation: Also varies, with some early-stage companies achieving notable post-money valuations.

Conclusion

The carbon & emissions tech sector continues to be a key focus for venture capital, despite ongoing challenges such as US tariff policies and policy uncertainty. North America and Europe remain the primary regions for investment, with the industry segment leading in deal value. Early-stage funding is concentrated in areas like green chemicals, biological carbon removal, and building energy efficiency, while exits remain limited. The sector's growth is closely tied to regulatory developments and policy support, with the EU's ETS2 and US DAC funding decisions playing a significant role in shaping future opportunities.
