GuiDanCe worked for the support of the Green Digital Charter that at its turn aims to improve the quality of life in cities through the use of digital solutions. The Digital Single Market, the Energy Union, the Urban Agenda and the European Commission's Investment Plan for Europe (Juncker Plan) have provided the framework for the EU's policies, and acknowledge the increasing role of cities and their citizens in helping to shape and achieve policy goals. Cities across Europe are encouraged to deploy integrated infrastructure, develop open urban platforms and draw up European standards for smart cities, enable the emergence of a collaborative and co-creative urban ecosystem and further develop public procurement strategies for innovation. Given the widely recognised need for technology and infrastructure-driven changes, it is even more important to highlight and exploit the social benefits of the digital economy. As the cities are entering a new stage in their evolution, they need to work towards becoming 'smart cities', where innovative technology applications are used to address the societal, economic and sustainable development challenges, improving the quality of life for all citizens. The Green Digital Charter and GuiDanCe commit cities to work together to deliver on the EU's objective of expanding the use of digital technologies that improve the life of their citizens and address the challenges of growth, sustainability and resilience.
