The difference concerning implementation and transaction costs between the domestic and the international offsets is basically that with a domestic offset scheme the Colombian government can decide upon regulations and rules (while ensuring the quality and credibility of the system). While a domestic system has higher implementation costs, it can have lower recurrent transaction costs. Concerning technical feasibility the instrument is as complex as the domestic scheme. While it can profit from international rules and regulations, these can on the other hand be much more complex than rules designed domestically.
