Do you have a tested solution supporting the green transition? The ETU Open Call 1 invites projects, organisations, and practitioners to contribute their tools and approaches to a growing Mediterranean platform for knowledge sharing, transfer, and impact.

The Ecosystemic Transition hUb (ETU) has launched its first Open Call, inviting organisations, projects, and practitioners to submit tested solutions that support the green transition of Mediterranean territories.

The objective of the call is to expand the portfolio of solutions available on the ETU platform, complementing those developed within the Interreg Euro-MED Green Living Areas Mission.

The call is open to publicly available solutions that have already been tested in real contexts — urban, rural, coastal, or island — and that support local authorities in designing and implementing sustainable strategies and actions, particularly within one or more of the five key ETU themes:

• green resilient planning
• green energy systems
• green mobility
• green community engagement
• financing the green transition

Solutions may include:

• tools and digital platforms
• governance and participatory approaches
• planning methodologies
• financial instruments
• community engagement initiatives

Selected solutions will:

• gain visibility on the ETU platform
• be shared with a wide network of public authorities and practitioners
• contribute to knowledge exchange, policy discussions, and ETU events

Beyond visibility, the call aims to facilitate replication and scaling, enabling solutions to be adapted and implemented in new territories.

Particular attention will be given to solutions that support key planning processes such as Sustainable Urban Mobility Plans (SUMP), Sustainable Energy and Climate Action Plans (SECAP), and Urban Nature Plans.

This first call is part of a broader ETU roadmap. Future calls (ETU call 2 and ETU call 3) will support local authorities in testing and transferring individual solutions, as well as implementing integrated packages of complementary tools.

How to apply

Complete the online application form. Submissions will be reviewed on a rolling basis by the Community for Green Living Areas (C4LA) consortium.

Solutions that meet the eligibility criteria will be featured on the ETU platform.
