The Circular City Centre – C3 is a competence and resource centre led by the European Investment Bank and co-funded by the European Commission as part of the Circular Cities and Regions Initiative (CCRI).

C3 offers a Circular City Advisory (CCA) programme and a Circular Project Advisory (CPA) programme to support cities at various stages of their circular transition:

1. From interest and ambition to strategy (CCA 1 Programme)
2. From strategy to project pipeline (CCA 2 Programme)
3. From project pipeline to project implementation and preparation for funding (CCA 3 or CPA Programmes)

These services are provided free of charge to cities and are delivered with the external support of Circle Economy, Arup, ICLEI and ECORYS.

If your city would like to apply to the advisory programme, please fill in the expression of interest form for the CCA or CPA programmes and send it to C3@eib.org and cca-info@circle-economy.com.

Applications for the current round are open until 7 November 2025, with online Q&A sessions organised on 24 September 10:00-11:00 CEST and 22 October 10:00-11:00 CEST.
