The Carbonzero Registry

Carbonzero is committed to providing the highest quality carbon offsets, sourced through the most stringent verification practices, and based on principles of transparency and open audit trail.
The Carbonzero Registry is a public search portal for Carbon Offset Certificate holders and 'Carbonzero Certified' clients to review the serialization and emissions reduction details associated with their offset purchase. The Carbonzero Registry and offset portfolio is regularly audited, ensuring every carbon offset purchased receives a unique serial number and is retired exclusively preventing offsets from being re-issued again at a later date.
