COP31 Antalya 2026 Blue Zone vs Green Zone — Pavilion Difference Explained for Buyers

COP31 Antalya 2026 (9-21 November 2026, Antalya Expo Center) operates two distinct zones — Blue Zone and Green Zone — each with different access rules, pavilion procurement processes, audience reach, and credentialing requirements. The Blue/Green Zone distinction is the most consequential pre-procurement decision for any organisation planning COP31 presence.

## Blue Zone — UNFCCC Conference Perimeter

The Blue Zone is the UN-managed secure perimeter where the actual climate negotiations happen. Access is restricted to:

• •Party (national government) delegations
• •Observer state delegations (non-Party states)
• •Intergovernmental organisation observers (UN system, OECD, World Bank, etc.)
• •Accredited NGO observers (constituency-based — Business, Environment, Indigenous, Local Government, Research, Trade Union, Women & Gender, Youth)
• •Accredited media (UN press accreditation system)
• •UNFCCC secretariat staff and conference services personnel

Blue Zone pavilions are typically built by: - National delegations — Country pavilions for Parties (most common — typically 100-500 m²) - Major IGO/UN agencies — UNDP, UNEP, UNICEF, World Bank pavilions - High-profile NGO consortia — Constituency-coordinated pavilions

Blue Zone build-up requires UNFCCC contractor accreditation. Build-up curfew, access logs, and material compliance documentation are strictly enforced. Pavilions are typically allocated through the host country presidency procurement process and confirmed 4-6 months before the conference.

## Green Zone — Host-Country-Managed Public Perimeter

The Green Zone is the public-access perimeter operated by the host country (Türkiye for COP31). Anyone can register and attend Green Zone — no UN accreditation required. Green Zone audience profile:

• •General public, students, climate-curious visitors
• •Local Türkiye media (beyond UN-accredited international press)
• •Business delegations attending side meetings
• •Academic conference attendees and researchers
• •Tourism and visitor traffic

Green Zone pavilions are typically built by: - Major sovereign-fund or state-owned enterprises — National oil companies, state banks, sovereign airlines - Major corporations with sustainability commitments — Microsoft, Unilever, Mahindra, etc. - NGOs without Blue Zone observer status — Climate advocacy groups, philanthropic foundations - Academic institutions — University research consortia - Türkiye-specific exhibitors — Turkish ministries beyond Foreign Affairs, regional Türkiye governments, tourism promotion bodies

Green Zone has more flexible procurement, lighter accreditation, and more permissive material rules (UNFCCC sustainability framework still applies but compliance documentation is less strict).

## Comparative Decision Framework

| Variable | Blue Zone | Green Zone | |---|---|---| | Audience | Climate negotiators, Party delegations, NGO observers, accredited media | General public, local media, business delegations, academics | | Access | UN accreditation required | Open registration | | Typical buyer | National foreign ministry / climate ministry | Corporations, sovereign funds, NGOs, host-country exhibitors | | Pavilion size | 50-1,200 m² | 50-2,000+ m² | | Procurement | Host-country presidency + UNFCCC | Host-country presidency direct | | Allocation closes | 4-6 months pre-show | 3-5 months pre-show | | Build budget | €120K-€1.8M typical | €80K-€2M+ typical | | Sustainability docs | Strict — material passport + carbon footprint mandatory | Recommended — material passport encouraged |

## Which Zone Should Your Organisation Choose?

• •Foreign ministry, climate ministry, or sovereign state environment agency → Blue Zone (canonical national delegation pavilion)
• •National oil company, sovereign airline, state bank with climate commitments → Either zone — Blue Zone if the entity has constituency observer status; Green Zone otherwise
• •Major multinational corporation with sustainability message → Green Zone (broader audience)
• •NGO with UNFCCC constituency observer status → Blue Zone
• •NGO without observer status, climate philanthropy, academic consortium → Green Zone
• •Host-country Türkiye ministry, regional government, university → Green Zone (lower friction, higher local audience)
