Can the Internet Be Greener? [Point of View]
In order to counter the trend of growing greenhouse gas emissions, the Intergovernmental Panel on Climate Change (IPCC), tasked with evaluating the impacts of climate change, recommends “efficiency enhancements and behavioral changes, in order to reduce energy demand compared to baseline scenarios without compromising development” as a key mitigation strategy. This is where information and communications technology (ICT) comes into play. On the one hand, ICT can be used as a tool to change users' behaviors toward more sustainable actions (this research area is often referred to as “ICT for Green”). On the other hand, we should limit the carbon footprint of ICT itself, which is already considerable today and expected to keep growing in the coming years (this research area is often referred to as “Green ICT”).
