C-Capsule’s team developed the first renewable energy certificate trading mechanism in Europe during the 1990s, eventually evolving into the Guarantee of Origin (GO). The team later designed and implemented the highly successful I-REC (International Renewable Energy Certificate), which is currently issued in over 40 countries. I-REC has become the established system for evidence to support origination claims by consumers in reporting their Scope 2 and Scope 3 emissions. It is internationally recognised by NGOs and consumer organisations to provide secure and reliable electricity origination information across the chain of custody.
