## About

Founded as a pure-play decarbonization investor, Green Circle Decarbonize Technology channels capital into engineered carbon removal pathways. The firm targets technologies spanning direct air capture, bio-oil sequestration, enhanced weathering, and ocean alkalinity enhancement — the machinery and methods required to build a gigaton-scale carbon removal industry. The investment thesis is narrow and technically demanding: back companies where the carbon removal is measurable, permanent, and additional. Green Circle's deployment model concentrates on pre-seed through Series A rounds, typically writing first checks into hardware-intensive startups that struggle to find risk-tolerant, science-literate capital. The firm structures both equity and milestone-based convertible instruments. Confirmed portfolio exposure includes companies operating across the US and European carbon-removal corridors, though specific holdings are not publicly cataloged. The firm's geographic reach extends to Iceland, the UK, and major North American tech hubs where carbon-removal talent clusters. Operational and financial scale remain opaque. Green Circle does not publicly report assets under management or team headcount, and no significant press coverage or regulatory filings illuminate its deployment cadence. The firm's public profile is unusually minimal, consistent with a vehicle that may function as a single-LP or family-capital-backed structure operating outside traditional fund cycles. A distinct structural feature is the firm's unclassified vehicle type, which may represent a holding company, a permanent capital vehicle, or a single-limited-partner fund. This architecture diverges from the standard venture fund model, potentially allowing Green Circle to hold illiquid assets indefinitely — matching the decades-long maturation timelines of many carbon-removal infrastructure projects.

## Questions

### What types of carbon removal does Green Circle invest in?

The firm targets engineered pathways including direct air capture, bio-oil sequestration, enhanced weathering, and ocean alkalinity enhancement, favoring hardware and bio-industrial approaches over nature-based offsets. Green Circle prioritizes methods where carbon removal can be measured, verified, and deemed permanent on geological timescales.

### In which geographies does Green Circle operate?

The firm deploys capital across the US and European carbon-removal corridors, with particular activity noted in Iceland, the United Kingdom, and North American technology hubs where carbon-removal talent and pilot projects are concentrated.

### Does Green Circle invest in carbon credits or nature-based solutions?

No. Green Circle exclusively backs engineered, technology-driven carbon removal companies. The firm does not participate in voluntary carbon markets, nature-based offset projects, or avoidance credits, maintaining a strict focus on permanent industrial sequestration pathways.
