POLICY MEETING PARTICIPATIOn


​Antarctic Treaty Consultative Meetings 2026

From May 11 to 21, 2026, the 48th Antarctic Treaty Consultative Meeting (ATCM 48) and the 28th Meeting of the Committee for Environmental Protection (CEP 28) took place in Hiroshima, Japan. More than 400 participants attended, including representatives from 29 Consultative and 15 Non-Consultative Parties, alongside Observers and Experts. 

The 3rd CEP/SC-CAMLR joint workshop on Climate Change and Monitoring
was held prior to the meetings (May 8 and 9), focusing on coordinating efforts to address climate change impacts on Antarctic marine ecosystems, and serving as a key collaboration between the CEP and the Scientific Committee for CCAMLR.

The project PI, Catarina Frazão Santos, attended both meetings and the workshop as part of the Delegation of Portugal. The Delegation of Portugal submitted several official policy documents for discussion at the meetings and the workshop, including documents addressing climate-smart ocean planning based on scientific publications developed under PLAnT. The latter pertain to Information Paper IP146, “Towards a climate-smart pathway for ocean management in Antarctica”, submitted by Portugal, Canada, and France; and Workshop Paper XP24, "Climate-smart marine spatial planning in Antarctic Treaty waters", submitted by Portugal. The PI presented IP146 herself at the CEP 28 meeting on May 14, and recommendations from XP24 at the Joint Workshop on May 9.

In 2024 and 2025, official policy documents on climate-smart ocean planning had already been presented by the Delegation of Portugal, namely ATCMXLVI/IP167
and ATCMXLVII/IP64. Also attending the meetings and workshop in Hiroshima were members of PLAnT’s Advisory Board, namely José Xavier (Head of Delegation of Portugal), Cassandra Brooks (SCAR) and Kevin Hughes (Delegation of the United Kingdom).
