Masdar City (Arabic: مصدر, maṣdar, literally the source) is a planned city in Abu Dhabi, in the United Arab Emirates. It is being built by the Abu Dhabi Future Energy Company, a subsidiary of Mubadala Development Company, with the majority of seed capital provided by the government of Abu Dhabi. Designed by the British architectural firm Foster + Partners, the city will rely entirely on solar energy and other renewable energy sources, with a sustainable, zero-carbon, zero-waste ecology. The city is being constructed 17 kilometres (11 mi) east-south-east of the city of Abu Dhabi, beside Abu Dhabi International Airport.
It will host the headquarters of the International Renewable Energy Agency (IRENA).
