The ICROA Accreditation Programme defines and promotes best practice in the financing of high-quality emissions reductions and use of carbon credits as an effective carbon management tool. The Programme is open to all organisations who provide a carbon offsetting service. Participation requires membership to both IETA and an ongoing annual independent audit to assure compliance to the ICROA Code of Best Practice. ICROA Accredited organisations may use the ICROA Accreditation Label.

The Label certifies that the company is compliant with the ICROA Code through an annual cycle of third-party audits.
