What are the different statuses of a carbon credit?

A carbon credit can fall under one of the following categories:

• Verified: the impact has occurred and has been thoroughly verified, making the credit ready for usage.
• Purchased: the carbon credit has been bought but has not yet been used.
• Claimed: the carbon credit has been associated with a company's activity and can no longer be used.
• Cancelled: the carbon credit has been verified but is no longer available (e.g., due to a forest fire). It can no longer be used, and the Standard's provision pool should replace it in case of sales.
• Pre-verified: some Standards allow pre-sales or offtake agreements of future verified credits to facilitate funding for high-CAPEX projects.
