The European Union's strong commitment to Net Zero Cities is inherently linked with the advancement of Local Digital Twins. This presentation will explore the synergistic relationship between these initiatives, focusing on two key opportunities for the aviation sector, particularly with the integration of Uncrewed Aircraft Systems (UAS).

Firstly, we'll establish UAS as an indispensable data engine for Local Digital Twins. Drones are vital for generating highly accurate 3D representations of urban and peri-urban environments and provide continuous, real-time data monitoring through advanced sensors. This expanded role represents a significant market opportunity for increasing drone utilization by public administrations, enabling comprehensive spatial and environmental data input crucial for sustainable urban planning and infrastructure management. This data also facilitates the integration of various transport modes within the digital twin, allowing for holistic urban analysis.

Secondly, Local Digital Twins empower public authorities to make evidence-based decisions through sophisticated simulations. These digital environments can be utilized to model and optimize future urban services, including those that might leverage advanced aerial operations. Simulations can assess environmental impacts, optimize operational efficiencies, and support regulatory compliance, aiding in the strategic planning and potential procurement of innovative urban solutions. The H2020 Flying Forward 2020 (FF2020) project directly demonstrated the practical application of drones for 3D digital twin representation and the simulation of regulatory compliance. Furthermore, recognizing procurement as a complex step for public administrations, insights from FF2020 on streamlining these processes will be referenced.

This presentation directly addresses the ATT Athens Clustering Event by showcasing "digital leadership in aviation" through tangible applications that support Net Zero Cities initiatives. It offers clear pathways to navigate "regulatory challenges and/or opportunities in digitising and greening aviation", with a specific highlight on the contribution of drone technology to greener urban environments.

Main messages:

• UAS are essential data engines for Local Digital Twins, a key enabler for achieving Net Zero Cities.

• Local Digital Twins empower evidence-based decision-making and streamline public sector procurement for sustainable urban development and transport.
