Sustainable City

What Sustainable City does

Sustainable City (Βιώσιμη Πόλη), legally "Cities Network for the Sustainable Development and Circular Economy," is a civil non-profit company (αστική μη κερδοσκοπική εταιρία) founded in 2017 and headquartered in Glyfada, Athens, Greece. The organization operates a network of more than 60 member municipalities across Greece and Cyprus, providing technical support for the development and implementation of proposals under European Union funding programs. Its core service offerings include EU program application support, sustainable urban mobility planning advisory (ΣΒΑΚ), Virtual Net Metering (Εικονικός Ενεργειακός Συμψηφισμός) implementation guidance, and energy poverty mitigation programs. The organization also operates a sub-brand, Europe Direct Peloponnisos, which serves as a citizen-facing information gateway to the European Union.

The organization's flagship product is the POWERPOOR Energy Poverty Mitigation Toolkit, an online platform developed through the EU-funded POWERPOOR project that includes three web/mobile applications: POWER-TARGET for identifying energy-poor households, POWER-ACT for motivating behavioral change in energy consumption, and POWER-FUND for information on energy communities and funding opportunities including crowdfunding. Sustainable City participates as a partner in multiple EU-funded consortia including POWERPOOR, WaysTUP!, BET (ERASMUS+ tourism skills), LANDS (nature-based solutions), ENVESOME (HORIZON environmental exposome), and THESEUS Hub4Circularity (HORIZON circular economy), with strategic coordination support from the National Technical University of Athens (NTUA).

The business model is structured as a member-based non-profit, with services delivered through direct engagement with municipal officials and participation in EU-funded project consortia. Sustainable City holds EN ISO 9001:2015 (2024) and EN ISO 14001:2015 (2022) certifications from TUV AUSTRIA, and is a member of Energy Cities, the European association of local authority energy agencies. The organization employs 11 staff and operates from a single headquarters in Glyfada, with leadership comprising President Dimitris Kafantaris (Δημήτρης Καφαντάρης) and General Director Giannis Georgizas (Γιάννης Γεώργιζας). Specific membership fees, project grant allocations, and overall budget figures are not publicly disclosed.

Product overview

Sustainable City is a city network for sustainable development and circular economy, functioning as a non-profit civil company.

Direct peers

• Housing Europe: European federation of public, cooperative and community housing providers. Already a POWERPOOR partner; comparable in operating as a pan-European member-based organization supporting public-good infrastructure initiatives.
• ICLEI - Local Governments for Sustainability: Global network of 2,500+ local and regional governments committed to sustainable urban development. Sustainable City is a partner in POWERPOOR, and both organizations operate as municipal networks delivering sustainability programming and EU project support.
• Energy Cities: European association of local authority energy agencies that Sustainable City is an active member of. Both unite municipalities around sustainable energy and climate action, providing technical support and EU program access; direct comparison in mandate and member base.
• POLIS Network: Network of European cities and regions working on sustainable urban mobility and transport innovation. Comparable in supporting municipalities on EU-funded sustainable mobility projects, mirroring Sustainable City's EU project portfolio.
• Eurocities: Network of major European cities that collaborates on EU policy and funding for sustainable urban development. Highly comparable as a multi-country municipal network facilitating access to EU programs and knowledge sharing.
• Climate Alliance: European network of municipalities focused on climate action and indigenous rainforest protection. Comparable in its role as a European municipal coalition delivering sustainability programming and EU project participation.

Emerging players

• REScoop.eu: European federation of energy cooperatives and community energy initiatives. Directly relevant to Sustainable City's energy communities and virtual net metering advisory work, though focused on the cooperative energy community niche.
• Eurotowns: European network of medium-sized towns sharing best practices on sustainable urban development. Comparable as a smaller-scale municipal network serving a similar European constituency with sustainability and EU program support.

Broad incumbents

• CEMR - Council of European Municipalities and Regions: Broad European umbrella association representing local and regional governments across Europe. Comparable as a pan-European municipal advocacy and support network, though at significantly larger scale and broader scope than Sustainable City.

Regional players

• EUROCITIES Working Groups: Themed working groups within Eurocities that address specific sustainability topics (mobility, energy, climate). Comparable to the topic-specific working groups that Sustainable City implicitly creates through its EU projects, though operated at a larger European scale.
