ITU Blog: Inviting contributions to ITU reports on Smart Sustainable Cities
Although cities account for only two per cent of global land area, they are responsible for more than 70 per cent of global greenhouse gas (GHG) emissions and 60-80 per cent of global energy consumption. Recognizing the sustainability challenges that cities are facing and the consequent need to revolutionize the way that they function, the emergence of the concept of a ‘smart city’ envisages the integration of ‘smart’ technologies into cities so as to increase efficiency while protecting the wellbeing of the environment and inhabitants.
It is estimated that 70 per cent of the world’s population will live in cities by 2050, making it essential that cities innovate to meet the challenges of the 21st century. And, with challenges increasing in line with population growth, achieving sustainable development remains atop the list of priorities.
