Türkiye hosts landmark D-8 climate meeting before COP31

Türkiye brought together environment and climate officials from across the D-8 Organization for Economic Cooperation in Istanbul on 17 July 2026, hosting the bloc's first-ever ministerial gathering focused solely on environmental and climate policy. The session, titled "Preparing for COP31: Advancing Climate Implementation through International Cooperation," was chaired by Murat Kurum, Türkiye's Minister of Environment, Urbanization and Climate Change and President-designate of COP31, and followed a Senior Officials' Meeting held the previous day.

Nine member states take part

Representatives from all nine D-8 member states attended the Istanbul gathering, underscoring the organization's growing focus on climate governance alongside its traditional economic mandate. In his address, Kurum pointed to the D-8's geographic scale, population size and combined economic weight as assets for shaping global climate policy, and laid out the priorities and action agenda Türkiye intends to pursue as COP31 host in Antalya.

Secretary-General calls for shared action

D-8 Secretary-General Ambassador Sohail Mahmood told delegates that climate change now ranks among the most pressing development challenges facing member states. He welcomed COP31's emphasis on implementation, adaptation, climate finance, loss and damage, and a just transition, arguing that economic growth, environmental protection and climate resilience "must advance together." Mahmood said progress would depend on technology transfer, knowledge-sharing, innovative financing and deeper South-South cooperation, and proposed that D-8 states set up a coordination mechanism ahead of COP31 while exploring a joint D-8 pavilion and side events in Antalya.

Istanbul Declaration adopted unanimously

The meeting closed with the unanimous adoption of the Istanbul Declaration, which formally expresses D-8 support for Türkiye's role as COP31 host and calls for shifting global climate efforts from pledges to concrete implementation through accessible finance and technology transfer. Ministers agreed to develop a D-8 Adaptation Action Framework covering 2026 to 2030, welcomed a proposed D-8 Environment and Climate Cooperation Platform, and committed to a long-term roadmap spanning adaptation, loss and damage, just transition, climate finance, the circular economy, clean energy and environmental education. The declaration also introduced the Istanbul Initiative for Climate Action and Sustainable Development as a voluntary cooperation framework, while ministers reaffirmed the role of small businesses, the private sector, academia and youth in driving the green transition.

Milestone ahead of Antalya summit

COP31 is scheduled to take place in Antalya from 9 to 20 November 2026, following Egypt's hosting of COP27 and Azerbaijan's hosting of COP29. Organizers say the Istanbul meeting marks a milestone for the D-8, formally adding environment and climate change as a strategic pillar alongside the bloc's existing economic cooperation agenda.
