UN-Habitat published the CityTwin Ethics framework on November 26. As more than 40 cities worldwide deploy digital twin systems — including Singapore, Helsinki, Shanghai, and New York — protecting resident privacy has become an urgent governance issue.
The CityTwin Ethics framework contains five core principles: data minimization (collecting only the minimum data necessary to achieve the function), purpose limitation (data must not be used beyond its original collection purpose), transparency (residents have the right to know what data is collected and how it is used), participation rights (residents have the right to request removal of their data from the digital twin), and secure storage (all data must be encrypted and set with automatic deletion deadlines).
The framework requires all city digital twin projects to complete a Privacy Impact Assessment (PIA) before deployment, with results made public. UN Deputy Secretary-General and UN-Habitat Executive Director Maimunah Mohd Sharif said: "City digital twins are powerful governance tools, but without ethical constraints, they could become the most sophisticated surveillance system in history." Twelve cities have signed commitments to operate their digital twin systems in accordance with the CityTwin Ethics framework.
