Rainbowstandard provides a carbon credit standard that certifies engineered removal and avoidance projects—such as biochar, bio‑CCS, enhanced rock weathering, and mineralization—using rigorous scientific methods combined with hands‑on field engineering. Independent auditors verify project data year‑round and publish it on a public registry, delivering traceable, auditable credits that meet ICVCM, ICROA, and ISO 14064‑2/14065 standards for corporate sustainability buyers.

Problem
Companies seeking carbon offsets often encounter credits that lack transparent verification, rely on theoretical models, or are disconnected from actual operational realities, making it difficult to ensure genuine emissions reductions. Project developers also face lengthy, opaque certification processes that hinder timely market access for engineered carbon removal solutions.
Solution
Rainbow offers a carbon credit standard that combines rigorous scientific methodology with hands‑on field engineering to certify engineered removal and avoidance projects such as biochar, bio‑CCS, enhanced rock weathering, and mineralization. Independent third‑party auditors validate and verify project data year‑round, while primary field measurements are used to confirm that each credit represents a guaranteed tonne of carbon mitigation. All verified data are published on a public registry, providing buyers with traceable, auditable evidence of real‑world performance. The certification workflow is streamlined to close in under three months, enabling developers to bring high‑integrity credits to market quickly. By aligning credits with buyers’ geographic and value‑chain priorities and documenting co‑benefits to biodiversity, water, and local employment, Rainbow connects demand and supply through a transparent platform.
Target Audience
Primary customers are corporate sustainability teams and procurement groups that require high‑integrity carbon offsets, as well as developers of engineered carbon removal projects seeking a fast, science‑driven certification pathway.
