London-based carbon removal certifier Isometric raises $40m Series A as European climate tech funding market stays active
Isometric, a London-based carbon removal certification provider, has raised $40m in a Series A funding round. AVP (formerly AXA Venture Partners) led the round, joined by existing investors Lowercarbon Capital and Plural. Isometric operates in the emerging market for high-quality carbon removal certificates — third-party verification of carbon drawdown claims made by project developers. Accurate certification is increasingly critical as voluntary carbon markets face scrutiny over credit quality, and corporate net-zero commitments drive demand for verified permanent removal. The raise reflects sustained investor appetite for climate infrastructure businesses with a data and verification angle. The round closed alongside a broader week of European climate tech deals including a €1.4bn raise by Swedish green steel company Stegra led by Wallenberg Investments.
Why this matters
Carbon certification platforms sit at the intersection of climate regulation and financial market infrastructure, raising questions about how certificates are structured, traded, and governed under emerging voluntary carbon market standards. Series A financing of this size for a London-based business activates technology finance, VC documentation, and regulatory advisory work. The quality of carbon credits is under increasing regulatory scrutiny in the EU and UK, and certification providers like Isometric are positioned to benefit from tighter standards.
On the Ground
On a Series A for a UK tech company, a trainee would assist with due diligence on the company's IP portfolio and technology licence agreements, and review any regulatory filing coordination required for a FCA-regulated data product. They would also support verification of the cap table and shareholder agreement schedules.
