Ban Ki-Moon will address heads of state and international delegates at WFES, a forum that promotes collaboration, innovation and investment opportunities in renewable energy, environment and clean technology.

The visit by the top UN official underscores the growing role Abu Dhabi and the rest of the UAE are playing in driving the global adoption of renewable energy and clean technology innovation. Through Masdar, a multi-faceted initiative advancing the development and deployment of renewable and alternative energy technologies, which is hosting the WFES, Abu Dhabi has demonstrated its long-term commitment to discovering a viable roadmap for sustainability.

"The UAE is making considerable efforts to find solutions to the world's energy challenges, in particular through the Masdar initiative and the World Future Energy Summit, which provides a platform for global cooperation in renewable energy and sustainability," Ban Ki-Moon. "Climate change is one of the defining challenges of our times," he added.
