ICAO is a specialized UN agency set up by the Chicago Convention and linked to the Economic and Social Council (ECOSOC). One of ICAO's main activities is the establishment of international standards, recommended practices and procedures covering the technical fields of aviation. ICAO came into being on 4 April 1947.
As regards the environment, most topics are treated and negotiated by the Committee on Aviation Environmental Protection (CAEP).
One of the last official documents synthesizing ICAO's environmental position is the Assembly Resolutions in Force A35-5 (2004).
However, in September 2007, ICAO's General Assembly adopted a new resolution (Assembly Resolution A36-22), where ICAO asks in particular for a mutual agreement between the EU and third countries before including third country airlines in the EU-ETS (see also Integration of the aviation in the EU-ETS for more details on the proposed inclusion). The EU and other ECAC Member States reserved their position regarding this aspect of the resolution.
