What happened
COP31 Kalyon Tower is operating within the Green Zone at the UN climate conference venue in Antalya. The tower offers light shows and opens its observation deck to visitors two times a day. Three of its levels have been designated as lounge areas, where receptions are held.
The ground-floor Start-up Zone covers 3,600m². It brings together ventures working on climate and sustainability solutions with investors, businesses and international stakeholders. Activities include presentations, networking and meetings with investors, according to Türkiye’s Ministry of Environment, Urbanisation and Climate Change.
For organisations attending COP31, the practical next step is to identify relevant Start-up Zone presentations and investor discussions, alongside the broader Green Zone programme.
Why it matters
The tower provides a defined meeting point for climate-focused entrepreneurs and potential commercial or financial counterparts at the summit site. Its start-up area is intended to support contact-building and the development of partnerships through direct meetings.
It is also part of a larger public-facing event area. The Green Zone occupies 582,000m² of the 1.1 million m² COP31 site and hosts activities for domestic and international visitors. The scale of the facilities allows business, cultural and academic programming to run alongside the conference.
Venue capacity and programme
The Green Zone’s Congress Centre includes a main hall for 5,000 people and other halls with capacity for a further 1,250 people, for a total of 6,250. Its programme covers opening ceremonies, cultural events, international panels and academic sessions.
Other venues include the 5,000-seat Great Amphitheatre, described by the ministry as one of the conference’s principal stages, and an 800-seat Small Amphitheatre. The smaller venue is used for concerts, cultural performances, youth activities, international panels and film screenings.
These facilities position Kalyon Tower’s start-up and visitor functions within a Green Zone designed for a broad mix of summit-adjacent activity.
