What’s newRainbow has been approved as a credit issuer by Frontier, the advance market commitment to purchase an initial $1 billion in permanent carbon removal by 2030.Frontier was founded by Stripe, Alphabet, Shopify, and McKinsey Sustainability to accelerate the development of carbon removal technologies by providing the long-term demand signal the market needs to grow durable CDR solutions.Frontier suppliers can now work with Rainbow for credit issuance, subject to Frontier also approving the relevant Rainbow protocol for their specific removal approach.
Why it mattersFrontier’s approval process is rigorous. They evaluate credit issuers across governance, scientific rigor, durable CDR expertise, market viability, and track record. Their published assessment noted that Rainbow "excels" in verification processes that emphasise real-world feasibility, supplier-friendly tooling, and fast turnaround times - all things we've built deliberately because they matter to project developers building viable businesses.For buyers, Frontier’s approval adds another layer of assurance. They are one of the most advanced buy-side organisations in the CDR market, and this approval reflects their assessment that Rainbow meets their requirements.This follows our ICVCM Core Carbon Principles eligibility approval earlier this year. Two of the most respected organisations in the CDR market have now independently assessed Rainbow and reached the same conclusion: Rainbow has built a solution that combines scientific rigour with field engineering expertise, giving buyers high-integrity, auditable credits and project developers a rigorous yet efficient path through certification and credit verification.
