There is no way to buy a Blue Zone badge and no route for an individual to register alone. Accreditation comes through a country delegation, an admitted organisation, the media, or the UN itself. If you are not already attached to one of those, that door is shut for 2026, because observer admission takes years rather than months.
The Green Zone is a real venue with its own programme, not a consolation prize. At Antalya it sits on the same site as the Blue Zone with its own entrance, and it carries the startup zone, the art programme and the academic programme. In Belém, 700,000 people passed through the COP30 Green Zone in the two months before the conference opened.
Two things to plan around. Registration gives you an entry QR code, so do it before you travel. And the Green Zone closes to visitors on 11 and 12 November, the two days of the , which also happen to be the Zero Waste day and the Resilient Cities day.
The free COP31 visa is only for registered participants. If you are travelling for the Green Zone alone, the normal Turkish entry rules for your nationality apply.
