Connected Urban Development (CUD) demonstrates how to reduce carbon emissions by introducing fundamental improvements in the efficiency of the urban infrastructure through information and communications technology (ICT).
Connected Urban Development 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 have 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.
