Focusing on five key themes, including low-carbon transition and food security, it seeks practical solutions to climate-related issues. Central Asia faces rising temperatures and desertification, demanding urgent action. Regional leaders are dedicated to establishing financial mechanisms and cross-border initiatives to bolster resilience.
Preparations are already underway, with regional consultations and thematic sessions:
- First consultation held in Almaty in March.
- Second consultation in Samarkand, strengthening collaboration.
- Sessions during the Central Asia Climate Change Conference (CACCC-2025) in Turkmenistan.
- Upcoming events, including COP30 in Brazil and the 80th UN General Assembly in New York.
The Central Asian Climate Fund’s Project Office, based in Kazakhstan, oversees coordination. The summit is expected to yield joint climate action plans, a regional finance mechanism, and new transnational projects, enhancing the region’s climate resilience.
Summit’s origins
At the 2023 Astana International Forum, President Tokayev unveiled plans for the Regional Climate Summit 2026. The initiative stemmed from the need to unite the five Central Asian nations—Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan—in a coordinated response to climate change. The region grapples with challenges like glacier melting and water scarcity, exacerbated by temperatures rising twice as fast as the global average. The proposal gained strong support from regional leaders, who view the summit as a chance to align policies and attract investments.
Tokayev’s announcement emphasized collective action. He stressed that the summit would go beyond diplomacy, aiming for tangible outcomes. The establishment of a regional climate fund and the launch of cross-border projects are among the top priorities. Astana’s selection as the host city reflects Kazakhstan’s leadership in regional environmental initiatives.
Core themes
The Astana Summit 2026 will focus on five critical themes, each addressing a pressing aspect of climate change. These themes were chosen based on Central Asia’s unique vulnerabilities to environmental shifts and natural disasters.
- Low-carbon transition: Promoting renewable energy and reducing greenhouse gas emissions.
- Climate adaptation: Building infrastructure resilient to extreme weather events like droughts and floods.
- Food security: Ensuring agricultural productivity amid changing climate patterns.
- Just transition: Supporting vulnerable communities during the shift to a green economy.
- Climate finance: Developing mechanisms to attract investments for sustainable projects.
Each theme will be explored in dedicated sessions during the summit, involving experts, scientists, and representatives from international organizations. The collaborative approach aims to align national policies and maximize the impact of regional efforts.
Regional preparations
Preparations for the summit began with seven regional consultations to ensure alignment among the countries. The first consultation, held in Almaty, brought together officials and experts to discuss climate priorities. The second, in Samarkand, deepened discussions on financing and cross-border projects. These meetings laid the groundwork for collaboration, with each nation contributing unique perspectives.
Thematic sessions have also been integrated into global climate events. At the CACCC-2025 in Ashgabat, Turkmenistan, Central Asian countries debated solutions for climate financing. Future sessions are planned for COP30 in Brazil and the UN General Assembly in New York. These international platforms amplify the region’s voice and attract global support for its initiatives.
The Central Asian Climate Fund’s Project Office in Astana leads the coordination, managing logistics, communication, and scientific data integration. Local and international teams are working together to ensure the summit’s success.
Climate financing
Financing is a cornerstone of the Astana Summit 2026. A key goal is to establish a regional financial mechanism to fund adaptation and mitigation projects, such as smart irrigation systems and renewable energy expansion.
Central Asia struggles to access global climate funding due to competition with other regions. The summit aims to address this by attracting international investors and organizations like the World Bank and the United Nations Development Programme. Consultations in Almaty and Samarkand explored financing models, including public-private partnerships.
Specific projects are already under consideration. In Kazakhstan, reforestation and forest conservation initiatives are gaining traction. In Uzbekistan, efforts focus on restoring the Aral Sea through joint green initiatives. These projects require significant investments, and the summit will be a critical moment to secure financial commitments.
Cross-border projects
Collaboration among Central Asian countries is vital for the summit’s success. Cross-border projects, such as shared water resource management, are central to the discussions. The region relies on rivers like the Amu Darya and Syr Darya, which span multiple countries, making cooperation essential.
A notable example is the joint effort between Kazakhstan and Uzbekistan to restore the Aral Sea. Tree-planting and ecosystem restoration initiatives are showing early promise. Another project involves developing efficient irrigation technologies to benefit farmers across the region.
- Transboundary river management: Monitoring systems to ensure sustainable water use.
- Shared renewable energy: Regional solar and wind energy networks.
- Ecosystem restoration: Projects like Aral Sea reforestation.
- Technical training: Programs to equip local communities with sustainable practices.
These projects highlight the potential of regional collaboration. The summit will provide a platform to formalize agreements and secure funding for large-scale initiatives.
Kazakhstan’s role
Kazakhstan plays a leading role in organizing the summit. As the host, the country is investing in infrastructure to accommodate international delegations. Astana, known for its modern architecture and global events, was chosen for its capacity to host high-level conferences.
President Tokayev highlighted national initiatives that align with the summit’s goals. The Taza Kazakhstan program, for instance, promotes environmental awareness among youth. Tree-planting campaigns and forest conservation efforts are also underway, with ambitious targets for the coming years. Kazakhstan aims to position itself as a model for sustainability in the region.
The creation of the International Biodiversity Fund, announced by Tokayev, is another key initiative. The fund seeks to protect endangered species, such as the snow leopard, and preserve vulnerable ecosystems. These efforts underscore Kazakhstan’s commitment to the global climate agenda.
Integration with global events
The Astana Summit 2026 will not be an isolated event. Its preparation is aligned with international climate conferences, ensuring Central Asia’s active participation in global discussions. The region’s involvement in COP30 in Brazil will be a key opportunity to present its priorities.
At the 80th UN General Assembly in New York, Central Asian countries plan to showcase their joint efforts. These events provide platforms to attract funding and share best practices. The region has already demonstrated unity at events like the Central Asia Pavilion at COP28 in Dubai, themed “Five Countries, One Region, One Voice.”
Integration with global platforms strengthens Central Asia’s position. Regional leaders hope the Astana Summit will solidify this visibility, securing support for long-term projects.
Regional challenges
Central Asia faces unique climate challenges. Temperatures in the region are rising twice as fast as the global average, leading to droughts, floods, and glacier melting. These phenomena threaten water and food security, particularly in rural areas.
Desertification is another pressing issue. In Kazakhstan, vast areas of degraded land impact agriculture. In Uzbekistan, the shrinking Aral Sea has caused dust storms, affecting public health. Solutions like tree-planting and sustainable agricultural technologies are being tested but require scaling and funding.
Economic barriers also pose challenges. Transitioning to a green economy demands massive investments, which not all governments can afford independently. The summit aims to overcome these obstacles by fostering partnerships and attracting external resources.
Expectations for 2026
The Regional Climate Summit in Astana is seen as a game-changer for Central Asia. Regional leaders anticipate concrete agreements, such as the formalization of the climate fund and the launch of new projects. Collaboration among countries will be critical to achieving these goals.
Regional consultations and thematic sessions will continue throughout 2025, refining the summit’s priorities. The involvement of international organizations like the World Bank and the UN will be crucial for the event’s success. Astana is preparing to welcome thousands of delegates, with modern infrastructure and a detailed logistical plan.
The summit’s outcomes will have lasting impacts. Cross-border projects, such as river management and renewable energy expansion, could transform the region. The establishment of a regional financial mechanism will also open doors for investments, benefiting local communities and strengthening climate resilience.
