CEN TC465 Climate-Neutral Smart Cities and Communities

Executive summary

The report reviews how European standardisation can support climate-neutral and smart cities. It focuses on the work of the CEN/TC 465 Ad hoc Group, which was set up to connect sustainability, digitalisation and urban development with Europe’s 2050 climate-neutrality objective.

The group examined existing standards, EU policy frameworks and city-level case studies. It looked at tools such as local digital twins, data spaces, AI, positive energy districts, Climate City Contracts and Local Green Deals.

The report finds that standards can help turn local climate and digital innovation into scalable practice. They can support interoperability, procurement, monitoring, data governance and coordination across cities, regions and EU initiatives.

Case studies from cities including Aarhus, Aalborg, Cork, Kranj, Limassol, Turin and Padua show both progress and gaps. Common challenges include fragmented data governance, limited coordination, organisational silos and the need for practical tools that local governments can use.

The report recommends stronger links between research projects, city practice and standardisation. It calls for better inclusion of cities and communities in standards work, clearer routes for turning project outputs into standards, and stronger alignment with international bodies such as ISO, IEC and ITU-T.

Key proposed actions include creating a new CEN/TC 465 working group on climate-neutral and smart cities, revising the committee’s business plan, integrating relevant case-study outputs into the standardisation pipeline, and developing standards for local digital twins, AI, positive energy districts and smart public services.
