ICLEI at SB64

IMPLEMENTERS AT THE CENTER

Cities and regions at the heart of the Paris Agreement’s implementation phase

Each year in June, Bonn, Germany, becomes the focal point of global climate negotiations with the UNFCCC’s Bonn Climate Talks —formally the sessions of the UNFCCC Subsidiary Bodies (SBs)—marking the mid-year checkpoint on the road to the annual COP.

With more than 6,000 national delegates and civil society representatives expected, SB64 (8–18 June) will address a wide range of issues, from mitigation and adaptation to finance, technology, and capacity-building, while preparing decisions for adoption at UNFCCC COP31 in Antalya, Türkiye, this November.

SB64 arrives at a critical moment. Following COP30, national climate plans are in place. The challenge now is turning those commitments into real-world implementation. For local and regional governments, Belém delivered mixed results. Recognition advanced, but the mandated framework that would formally place subnationals at the heart of climate implementation did not materialize.

At this high-level space, ICLEI is committed to bring the message that cities, towns, states and regions must be at the heart of the Paris Agreement’s implementation phase.

Daring Cities 2026 Bonn Dialogues

Held alongside SB64 from 10–12 June, the Daring Cities 2026 Bonn Dialogues bring together local and regional leaders, national governments, and global partners to engage directly with the policy processes and implementation challenges being discussed in the negotiating rooms.

This year’s Dialogues are organized around the defining challenges of the post-COP30 moment: Advancing NDC 3.0 implementation through multilevel action; building momentum ahead of the IPCC Special Report on Climate Change and Cities, expected in 2027; and strengthening the finance, partnerships and governance needed to scale what is already working.
