CTC's are so called because they are claimed reductions that have been through and passed a rigorous examination of their transparency, sustainability,and additionality amongst other tests. The examining and approving body then Approves, Accredits and Certifies (Validation Process) them as meeting all the citeria and requirements of the UNFCCC. Next the Approved Credits are Monitored, Tracked, Recorded, Reported and Registered on an annual basis by independent third parties sanctioned by the goveerning body with authority for the venue in question.The application of this total process makes them consistent with the rules, criteria and requirements for any juridiction in the world. They are therefore, fully tradable. Hence the title 'Certified Tradable Credits'.
