The fourth Climate Week of the United Nations Framework Convention on Climate Change (UNFCCC) and the parallel Baku Climate Action Week were hosted and organized by Azerbaijan at the Baku Congress Center on September 7-11.

According to the Ministry of Foreign Affairs, a total of 68 events were organized during the week, with nearly 2,700 delegates from more than 140 countries registering to participate.

In addition to state delegations, representatives from various international organizations, non-governmental organizations, the private sector, and academia attended the events.

As part of the UNFCCC Climate Week, eight mandated meetings were held on various aspects of the international climate agenda arising from the decisions of the Conference of the Parties, alongside events by the COP30 and COP31 presidencies and several sessions within the UNFCCC Executive Forum.

During the parallel Baku Climate Action Week, Azerbaijan organized a total of 37 events in line with the Action Agenda of the Azerbaijani COP29 Presidency, as well as on other topical issues.

In addition, in accordance with the relevant mandate adopted at COP30, a consultation was held within the framework of the "Mission 1.5" Troika mandate regarding the implementation of National Adaptation Plans (NAPs) and Nationally Determined Contributions (NDCs), with the participation of Azerbaijan, Brazil, Turkey, and Australia, which hold the presidencies of COP29, COP30, and COP31.

It should be noted that hosting the UNFCCC Climate Weeks is organized on the basis of the principle of rotation among UN regional groups.

Of the two UNFCCC Climate Weeks held in 2026, the first was organized in the Republic of Korea in the Asia-Pacific region in April of this year, and the second in Azerbaijan in the Eastern European region.
