Smart ICT services and The New Way of Living and Working can make a significant contribution to energy saving. We can save a lot of energy by reducing servers and data storage area. Working from home eliminates travel time and fuel consumption and flexible working reduces the need for office buildings. In 2011 we developed the “KPN Bespaarmeter”, an online tool for calculating potential energy, time and cost savings. This enables us to give current and potential customers an understanding of the financial benefits of Green ICT and The New Way of Living and Working. In 2012 we made this tool available on the internet (www.kpnbespaarmeter.nl). We drew attention to this savings tool at congresses and symposia such as the National Sustainability Congress. In 2013 we aim to intensify the use of the KPN Reduction meter and further refine the tool. In addition, we want to examine in conjunction with customers how we can measure the actual savings.
