The future of Connected and Sustainable Cities. A short video highlighting how ICT can deliver the Smart and Green environmental agenda, and meet stakeholder objectives for economic growth whilst delivering a sustainable urban future. Connected Urban Development (CUD) demonstrates how to reduce carbon emissions by introducing fundamental improvements in the efficiency of urban infrastructure through information and communications technology (ICT). CUD was born from Cisco’s commitment to the Clinton Global Initiative to participate in helping reduce carbon emissions. The founding CUD cities are: San Francisco, Amsterdam, and Seoul. In 2008 four new cities joined the program - Birmingham, Hamburg, Lisbon, and Madrid - beginning a new phase for CUD and opening new avenues for collaboration in promoting smart urban environments globally.
