ICAP is an open forum comprised of public authorities and governments that have established or are actively pursuing carbon markets through mandatory cap and trade systems.

ICAP encompasses ETS from various government levels: regional, national and sub-national (states, provinces, cities).

Launched on October 29, 2007 in Lisbon, Portugal, by leaders of more than 15 governments, the partnership now counts 31 full members and 5 observers.
