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.

The Interreg Euro-MED Green Living Areas Mission has launched the Ecosystemic Transition hUb (ETU), an initiative designed to support Mediterranean cities and regions in accelerating the green transition.

By connecting projects, experts, and local authorities, the ETU acts as a practical support framework, helping territories identify, combine, and apply tested solutions adapted to their local context.

The ETU builds on several years of work under the Interreg MED Programme, where it was initially developed as the Ecosystemic Transition Unit. At that time, it focused on supporting rural and island municipalities in advancing their renewable energy transition through a systemic approach addressing energy planning, governance, and infrastructure.

With the launch of the Green Living Areas Mission, the concept has evolved into the Ecosystemic Transition hUb, expanding its scope beyond renewable energy to address the broader green transition of territories — from mobility and climate adaptation to community engagement and spatial planning.

At the core of the ETU lies a simple idea: territories function as interconnected systems. Decisions related to energy, mobility, land use, governance, and finance are deeply interdependent and must be addressed in an integrated way.

To support this approach, the ETU framework is structured around six pillars — organisational, environmental, social, territorial, technological, and financial — reflecting the key dimensions that need to evolve together to build resilient and sustainable living areas.By bridging knowledge, tools, and actors across the Mediterranean, the ETU initiative aims to turn tested and successful solutions with high replication potential into actionable approaches that can be scaled and implemented across territories, supporting local authorities in moving from strategy to implementation.

As part of the Ecosystemic Transition hUb (ETU), the Green Living Areas Mission is developing the ETU platform — a space where cities, practitioners, and project partners can explore and share a growing portfolio of solutions for the green transition.

The platform functions as both a knowledge hub and a practical tool, providing access to methodologies, digital tools, and real-life experiences developed across the Mediterranean.

The core of the platform is a growing portfolio of tested solutions, developed and implemented in real territorial contexts. These include tools, methodologies, digital platforms, and practical approaches that support local authorities in addressing concrete challenges.

For each solution, the platform provides key information, including:

• the challenge addressed and the solution’s added value
• the organisations behind it
• direct access to the solution

It also highlights where and how the solution has been tested, presenting the results achieved and the lessons learned from pilot experiences.

To facilitate navigation, solutions are structured using the ETU Matrix, which combines five themes of the green transition — green resilient planning, green energy systems, green mobility, green community engagement, and financing the green transition — with six cross-cutting pillars reflecting the ecosystemic dimensions of territorial transformation (organisational, environmental, social, territorial, technological, and financial).

Beyond accessing solutions, users can:

• stay informed about the latest ETU news and upcoming events
• connect with local partners through the Territorial Antennas
• learn about ETU calls to submit new solutions or benefit from transfer opportunities

The platform is designed to support key territorial planning frameworks such as Sustainable Urban Mobility Plans (SUMP), Sustainable Energy and Climate Action Plans (SECAP), and Urban Nature Plans.By bridging knowledge and practice, the ETU platform helps local authorities move from inspiration to implementation, facilitating the transfer and scaling of solutions across Mediterranean territories.
