Do you trust corporate carbon removal projects to deliver on their promised environmental impact?

Residual Carbon launched a buyer portal designed to streamline due diligence for carbon removal projects. Twenty-five major buyers have already subscribed to the platform to model potential purchases.

Why it matters

The portal aims to accelerate the purchasing process by shifting detailed due diligence to earlier stages. It provides standardized access to pricing, delivery schedules, and project risk assessments that previously required time-intensive manual review.

Twenty-five major buyers are currently using the portal to compare portfolios, contributing to a broader market that saw 2.3 million tonnes of durable carbon removal contracted in Q1 2026.

Operators managing carbon portfolios should evaluate whether centralized data platforms like this reduce the time required for internal project due diligence. Procurement teams should monitor if the increased visibility into risk assessments allows for more accurate cost-benefit modeling.

The takeaway
