Cluj-Napoca has become one of Romania’s most active centres for climate-related planning, taking part in European initiatives that rely on detailed environmental monitoring to support long-term urban development. As Romania marks its National Day each year on 1 December – commemorating the 1918 union that laid the foundation for the modern state – the city continues to build its own path forward through regional cooperation and data-driven policy.
Cluj-Napoca is one of ten pilot locations selected for the Horizon Europe CLMS-Cities project, which combines satellite-based products from the Copernicus Land Monitoring Service with additional environmental and urban datasets. This integration gives local authorities a sharper view of how CO₂ emissions change across the city, making it easier to assess how land use evolves and how urban expansion affects climate goals.
The Copernicus Sentinel-2 image – captured on 17 October 2025 – shows Cluj-Napoca within a landscape of hills and agricultural fields. From above, the contrast between compact neighbourhoods and open terrain highlights the city’s position within a wider ecological setting, offering a clear reference for observations that track shifts in land cover and the shape of the urban footprint.
Cluj-Napoca has held the EU Mission for Climate-Neutral and Smart Cities label since 2023, recognising its commitment to planning that incorporates both environmental data and local needs. The work undertaken through CLMS-Cities supports this direction by providing consistent Earth observation information that helps guide decisions on development, emissions, and the use of surrounding land.
More information about how Copernicus supports the EU Cities Mission and the CLMS-Cities initiative is available on the project’s website.
