In March Cisco announced that it has signed a Memorandum of Understanding (MoU) with Metropolis, an association comprised of 106 of the world's largest cities, to develop its "Vision 2030" for sustainable cities around the world. As part of this MoU, Cisco will advise Metropolis on how to build a collaborative operating model between Metropolis member cities and establish an Urban Leadership Academy to demonstrate how future cities can effectively use technology to advance clean public transportation, decrease pollution through intelligent urban development, offer pervasive access to citizen-centric services and support sustainable economic growth.
