The 48th Antarctic Treaty Consultative Meeting and the 28th meeting of the Committee for Environmental Protection closed in Hiroshima on May 21, 2026. The Antarctic and Southern Ocean Coalition said the meeting made progress on peace, science and education, but left two urgent items unresolved: binding tourism rules and Specially Protected Species status for the emperor penguin.
Japan chose Hiroshima as the venue, and the setting framed Antarctica as a natural reserve devoted to peace and science. Delegates marked the 35th anniversary of the Environmental Protocol. Patricia Cavalcanti, program director for Asia-Pacific at Agenda Antártica, called the Antarctic Treaty a mid-20th-century miracle and said parties have a historic window to match that legacy with 21st-century ambition on a healthy environment.
Tourism talks moved, but rules remain voluntary
ASOC welcomed progress toward a framework for regulating tourism, and continued to urge parties to adopt binding rules. The reason is the surge in visitor numbers. Without a legally enforceable framework, ASOC said, the growing commercial footprint risks irreversible pressure on Antarctic wilderness and fragile ecosystems. Ricardo Roura, senior advisor at ASOC, said voluntary guidelines cannot work while commercial tourism operations expand rapidly. Developing a framework is a start, he said, but the ATCM must turn discussions into mandatory, legally binding regulations before tourism growth outpaces the ability to protect the environment and the intrinsic values recognized under the Protocol.
Emperor penguin protection fell short
A proposal to designate the emperor penguin as a Specially Protected Species came before the meeting. The IUCN Red List had elevated the species to Endangered earlier this year. Scientific bodies, including the Scientific Committee on Antarctic Research, reported abrupt and accelerating changes across Antarctic systems and exceptional sea ice loss. Sea ice is critical emperor penguin habitat.
Parties reaffirmed protection of the emperor penguin as a priority, but stopped short of formal Specially Protected Species status. ASOC said only a small minority of parties opposed the proposal. Formal status would have triggered a coordinated framework of conservation measures aimed at protecting the species from habitat loss and the risk of functional extinction by 2100 under business-as-usual emissions trajectories. Rod Downie, WWF chief adviser for polar and oceans, said the barometer is flashing red and protections are being stymied by a small number of parties. He said the endangered emperor penguin is a reminder that the climate and nature crises are intertwined, and he looked to next year's meeting in the Republic of Korea to deliver meaningful action.
Climate is not a regional issue
ASOC linked peace and environmental protection, warning that safeguarding life-sustaining systems such as the collapsing Antarctic ice sheet is fundamental to preventing global conflict. The coalition cited global tracking surveys by Pew Research Center and the Gallup World Risk Poll showing that 67% of humanity, nearly two-thirds, view the climate crisis as a major threat to the planet's future. Pam Pearson, director of the International Cryosphere Climate Initiative, said the ATCM cannot treat Antarctica as an isolated regional issue. She said the forum should use its diplomatic leverage to convey to the UNFCCC and world leaders the extreme threats of Antarctic ice sheet melt unless fossil fuel emissions are cut urgently.
ASOC also worked to make polar diplomacy visible in Japan. It held a public panel in Tokyo, the photo exhibition From Antarctica to Hiroshima, and a Youth Art Contest. Those events coincided with an official ATCM Outreach and Education Workshop, which occurs only once a decade. Randal Helten, representative director of Friends of the Earth Japan, said civil society should be seen as a key stakeholder in the Antarctic Treaty System. ASOC is urging parties to improve transparency so the public can see and reach the diplomacy that affects it.
The next ATCM is in the Republic of Korea. That meeting is the deadline to watch for decisions on emperor penguin protection and binding tourism rules.
