Welcome to the
Green Digital Tool Kit

Cities across Europe are signing the Green Digital Charter which commits them to a wide range of activities towards green digital progress. The three core commitments are: running 5 large scale pilot projects, reducing their ICT carbon footprint by 30% and cooperating with other signatories.

This Toolkit helps interested cities to build on the experiences of others. Find out about sharing activities and tools to improve your green performance. Find out more information here.

Featured Activity

Pilot thin-client system

City: Lisbon
Activity Type:  Operational
Application Area:  Green ICT
Role of ICT:  Efficiency

In 2013 a thin-client IT system was implemented in Lisboa E‑Nova, Lisbon’s Municipal Energy-Environment Agency. This replaced multiple Desktop systems. The new system uses an open-source operating system and applications, allowing to gain experience and knowledge in its usage. Simultaneously, an internal policy of using open standards for digital documents was adopted. This aligns Lisboa E‑Nova's digital documents with the National Regulation on Digital Interoperability, and it ensures that the information is available to anyone. 40% of the Desktops replaced were using a closed‑source operating system that is now known to reach end‑of‑support in April 2014.
