Carbon removal specialist opens structured financing round for engineered and nature-based projects with a minimum offtake contract value of $3 million.

Carbonaires today opens its Request for Proposals (RFP) for offtake-backed financing of high-integrity carbon removal projects globally.
The RFP is open to all engineered and nature-based carbon removal pathways, including biochar, enhanced rock weathering, BECCS, direct air capture, mineralisation, afforestation and reforestation, soil carbon and blue carbon. Projects must hold a signed or imminent offtake agreement with a minimum contract value of $3 million.
Financing is arranged against each project’s existing or imminent offtake, with investment size determined case by case. Credits flow to the offtake counterparty or are retired under the terms of the offtake agreement.
RFP for Financing Offtake-backed Carbon Removal Projects — overview and key dates.
High-quality carbon removal projects are often constrained not by science, demand, or technology readiness, but by limited access to appropriately structured capital. This is most acute for project developers at the frontier, where projects are frequently ahead of available financing structures. This RFP connects qualified projects with Carbonaires’ global network of institutional investors through a structured process. This RFP is designed to close that financing gap.
The carbon removal market has the projects and it has the buyers. What it has consistently lacked is the financial infrastructure to connect them at scale. This RFP is part of how we build that infrastructure.
— Rasih Ozturkmen, CEO and Co-Founder, Carbonaires
For four years, Carbonaires has focused on building the high-integrity supply side of the carbon market. It has developed the financial infrastructure to scale carbon removal, originating projects, structuring financing, and executing offtake-backed transactions as a financial counterparty to developers.
Combining capital markets and trade finance experience with scientific expertise, Carbonaires delivers investment-grade opportunities for institutional investors. This was demonstrated through a landmark, first-of-a-kind transaction with UBS in 2024 and is now being deployed across a growing pipeline. Through this RFP, Carbonaires extends access to meet increasing demand.
Carbonaires will assess applications through a structured and transparent evaluation framework, focusing on carbon integrity, delivery confidence, financial robustness, governance, and overall strategic fit. The process is pathway-agnostic, with projects evaluated on the credibility of their carbon claims, likelihood of delivery against contracted volumes, and the strength of the proposed financing structure.
Questions should be submitted via the Carbonaires RFP platform. Responses will be issued to all applicants simultaneously.
Project developers can register and submit an application on the Carbonaires RFP Hub at rfp.carbonaires.com/signup.
