This summit examines opportunities where information and communications technology (ICT) is used as a tool to improve environmental and societal functions, and improving the energy efficiency, carbon footprint and lifecycle management of ICT itself. ICTs are currently transforming all spheres of human activity and creating a paradigm shift similar or even greater in scope and impact to the industrial revolution. ICTs are a key driver of sustainable development, with the potential to reconcile socioeconomic benefits with positive environmental impacts. The summit’s objective is to identify the combination of key technological, commercial, and public policy challenges that must be overcome to achieve sustainability in our connected world. As such, it seeks to build a broad dialogue among the research community, ICT practitioners and its vertical application sectors, equipment and technology providers, the ICT standardization community, and with public policymakers.
