After seven years, a major EU initiative has demonstrated that some of Europe’s oldest protected cities can slash carbon emissions while keeping their historic facades intact. The POCITYF project, coordinated by João Cravinho of Portuguese utility EDP, delivered proof that heritage preservation and local clean energy production need not conflict.
Urban areas generate roughly 70 percent of global greenhouse gas emissions, yet they also house most Europeans. That makes them both the core problem and the most promising venue for climate action. Cravinho argues that available technology already suffices. What lags, he contends, involves political will, adaptive regulation, and genuine citizen participation.
The project’s two flagship cities produced compelling early numbers. Alkmaar in the Netherlands reached approximately 50 percent energy self-supply during the first monitored year, while Évora in Portugal hit around 20 percent. Neither city sacrificed protected streetscapes to do so. Solar panels blended discreetly into existing structures, and energy sharing took root locally.
Meanwhile, six fellow cities across Europe tested how to adapt the methods to their own legal and cultural settings. Bari, Celje, Granada, Hvidovre, Ioannina, and Újpest each contextualized solutions rather than copying exact installations. Some pairings disappointed, such as certain battery configurations coupled with photovoltaic arrays, but those failures informed the broader replication framework.
As a result, the project leaves behind a 49-partner network, practical know-how for historic districts, and a methodology other municipalities can follow. Cravinho stresses that regulatory flexibility and citizen-led energy communities will determine whether the gains scale. Historic character, the project shows, does not block climate action; it simply demands smarter design.
