Comment | As Cop30 opens in Brazil, it is time for the art world to embrace ethics with aesthetics

COP30, the United Nations Climate Change Conference, opens in Belém, Brazil, with culture officially on its agenda for the first time, thanks to advocacy from the Amazonian activist group Labverde and Art of Change 21. The conference features interventions and performances by eight Brazilian and indigenous artists, including photographer Christian Braga and activist Beto Oliveira, alongside a flurry of artist-led activities in UK galleries and institutions. The article also marks the tenth anniversary of Gustav Metzger's environmental art project "Remember Nature," which mobilized over 140 artists including Judy Chicago, Olafur Eliasson, and Marina Abramović, and was revisited on November 4, 2025, with sixteen English arts institutions hosting public projects.
