The Cop30 conference served as a forum for discussions on global climate action, following up on the Cop28 agreement to "transition away" from fossil fuels. A notable outcome included the signing of the Declaration on Information Integrity on Climate Change by 15 nations, among them Germany and Belgium.
Advocacy efforts were also prominent, with WaterAid campaigners calling for water to be central to governments' climate plans. Perspectives from attendees varied, with Mexican climate activist Maria Reyes expressing that the militarization surrounding Cop30 was "confusing and disappointing."
Observations were made regarding views presented by the oil industry, including the statement that "the climate has always changed," as anti-fossil fuel protests took place outside the conference venue. Discussions further addressed challenges such as the role of authoritarianism in climate action.
