Insights
- The 48 carbon removal funding deals in this list represent more than $1.08 billion in disclosed funding between Q1 2024 and Q2 2026.
- Direct Air Capture attracted many of the largest carbon removal funding rounds. Heirloom raised $150 million, Climeworks raised $162 million, and CarbonCapture raised $80 million.
- The carbon removal market is becoming more diverse. The funding list covers air capture, biochar, ocean removal, mineralization, enhanced weathering, biomass storage, and carbon project infrastructure.
- Funding activity was strongest in 2024 by deal count. The carbon removal market recorded 25 deals in 2024, compared with 16 deals in 2025 and seven deals through Q2 2026.
- Large rounds had a major effect on total funding. Climeworks and Heirloom raised a combined $312 million, which represents almost 29% of all disclosed funding in this list.
- Ocean carbon removal companies are attracting more investors. Gigablue, Equatic, Captura, Planetary Technologies, SeaO2, Vycarb, and pHathom Technologies all secured funding.
- Enhanced weathering is moving beyond laboratory research. Terradot, Alt Carbon, Eion, CREW Carbon, and other carbon removal companies are funding field deployments and commercial expansion.
- Biochar remains an important part of the carbon removal market because biochar projects can combine durable storage with soil and agricultural benefits.
- The carbon removal market includes both technology developers and project operators. Some companies build capture equipment, while others develop projects, measurement systems, and carbon credit infrastructure.
- Early-stage funding remains common in the carbon removal market. Several companies raised less than $5 million to test technologies, build pilot projects, or improve measurement systems.
Summary table of the funding deals for the carbon removal market since 2024
We define the carbon removal market as technologies and projects that remove carbon dioxide from the atmosphere and store it durably.
It includes Direct Air Capture, Biochar Projects, Enhanced Weathering, Biomass Carbon Removal, Ocean Carbon Removal, and Carbon Mineralization.
It excludes broader adjacent markets unless the product is built specifically for this use case.
We focused exclusively on pure players, defined as companies with at least 70–80% of their business directly tied to the carbon removal market.
Our analysis has been done at a global level with a minimum funding threshold of $300k.
