The Common International Classification of Ecosystem Services (CICES) developed from the work on environmental accounting undertaken by the European Environment Agency (EEA). It supports their contribution to the revision of the System of Environmental-Economic Accounting (SEEA) which is currently being led by the United Nations Statistical Division (UNSD).
Version 5.1 is now available and can be downloaded from the CICES website: www.cices.eu. It now replaces Version 4.3 which was published in 2013.
