The European Commission (DG REGIO) has defined and agreed with its Member States, 13 regions for transnational co-operation. In addition, specific EU agreed strategies exist for two transnational regions (Baltic Sea Region, Danube Region). Various other EU programmes and other organisations provide information on adaptation strategies and actions across countries in the EU, the wider Europe and its neighbouring countries.

This section provides information on strategies and actions that have been developed or are currently under development for the EU transnational regions and for other regions and countries.
