The Antarctic Treaty Consultative Meeting (ATCM) is the primary forum in which the representatives of Parties to the Antarctic Treaty exchange information, formulate measures, and make decisions and resolutions in order to promote the principles and objectives of the Treaty. The outcomes of Treaty meetings are adopted by consensus of the Consultative Parties.
The ATCM meets annually. The Consultative Parties host the meeting according to the alphabetical order of their names in English. In 2015, Bulgaria will host the ATCM for the first time.
