Cities account for roughly 80 percent of the energy consumed worldwide and generate roughly 75 percent of all carbon emissions. With more than two-thirds of the world’s population predicted to live in urban areas by 2050, cities are coming under increasing pressure. Digitally connected smart cities can help overcome some of the most pressing challenges of our time, including clean water, adequate waste removal as well as reduced pollution caused by buildings. The Expo 2020 Dubai site, with infrastructure connected by Siemens digital technology, provides a blueprint for smart cities globally. As the Premier Partner for Infrastructure Digitalization at Expo 2020 Dubai, Siemens has digitally linked more than 130 buildings at a purpose-built site twice the size of Monaco.
