The project that was unveiled in 2007, aims to be the world’s first carbon-free city by relying entirely on solar and other renewable energy sources. It also aims to be completely zero-carbon and zero-waste by banning cars within the city, allowing its residents to rely on the public transport system and personal rapid transit systems. It is an ambitious plan, but Abu Dhabi isn’t skimping on money for the project investing over US$15 billion in it thus far. It is expected to cost US$22 billion when it is finally finished. Currently, the development is on track with Khaled Awad, director at Masdar’s property uni, telling reporters that the city’s first phase will be operation by 2013, with the second phase designs ready to go immediately after.
