Green information and communication technology (ICT) for smart cities was the subject of the 6th Green Digital Charter webinar on 7 November. Three experts presented their work.

LinkopingFredrik Eriksson is ICT strategy officer in Linköping. His city has already developed a broad range of environmentally friendly ICT solutions. Linköping wants to become CO2 neutral by 2025, partly by switching to renewable energy sources. Back in 2013, the city adopted a new travel policy for its municipal staff: “Travels shall only take place when necessary; travels shall, as far as possible, be replaced by video, phone, and web conferencing.” The ensuinggreener’ meetings and fewer trips have had a positive effect on participants’ availability and efficiency, he said. Eriksson’s presentation is available here.

GreenITJaak Vlasveld, director at green IT Amsterdam, presented a series of case studies and projects that use or develop green IT tools and solutions. According to Vlasveld, power management should be enabled at hardware level (computing resources) whenever possible. The other layers to be considered in green cloud models are software applications, virtualisation platforms, and data centre infrastructure, he said, stressing that beyond performance, the impact of energy efficiency improvements should also be explicitly assessed. Vlasveld’s presentation is available here.

ICTfootprint.euSilvana Muscella, founder and CEO of Trust-IT Services, presented the project, which aims to become the consolidated effort that, at European level, raises awareness of metrics, methodologies, and best practices in measuring the ICT sector’s energy and environmental efficiency, and that facilitates their broad deployment and uptake. The project has developed a range of tools and services, which you can consult at One such tool is the map of ICT standards. Whether you work for a public administration, an ICT-intensive SME, or an ICT supplier, we strongly encourage you to join the community to benefit from these services. Muscella’s presentation is available here.
