The Fund's key achievement was the organization and hosting, jointly with the Ministry of Ecology and Natural Resources of the Republic of Kazakhstan, of the Regional Ecological Summit 2026.

The event was attended by the presidents of the Central Asian countries, Armenia, Georgia and Mongolia, the Prime Minister of Azerbaijan, senior state officials from Central, South and Southeast Asia, the CIS and other regions, heads of UN system organizations and of international organizations such as the OSCE, EU, ECO, ICESCO, SCO, OTS, CICA, IOFS (Islamic Organization for Food Security), ADB, EBRD, World Bank, GCF and IsDB, and heads of environmental agencies of the Central Asian countries as well as Armenia, Azerbaijan, Georgia, Germany, Belarus, Türkiye, Italy, China, Cambodia, Serbia, Mongolia, Croatia, Japan, Afghanistan, the Russian Federation and others. In total, more than 11,000 participants took part.

In addition to bilateral meetings and side events, the Summit comprised 58 thematic sessions, including 21 high-level sessions and 4 country sessions of the Central Asian states, covering climate policy, sustainable development, energy, adaptation, finance, water resources, biodiversity and just transition.

The main outcome of the event was the adoption of the Declaration of the Heads of State of Central Asia "Environmental Solidarity of Central Asia". The presidents confirmed their intention to step up efforts to develop joint regional positions and solutions within multilateral environmental processes, including negotiations on biodiversity, the management of chemicals and waste, combating plastic pollution, improving ambient air quality, and countering land degradation and desertification, as well as to promote a consolidated position of the region's countries on key international platforms.

A key result was the formation of a new regional architecture of cooperation and partnership, based on mutual support and consolidated practical cooperation between the states of the region and international partners.

In accordance with paragraph 24 of the Declaration of the Heads of State of Central Asia "Environmental Solidarity of Central Asia", adopted at the Summit, the presidents expressed their readiness to cooperate within the Project Office for Central Asia on Climate Change and Green Energy in order to accelerate regional action aimed at promoting the ecological transition in the region.
