The event's opening ceremony will feature speakers including the U.K.'s former Prime Minister Tony Blair, Dr. Jim Yong Kim, president of the World Bank, and Sir Richard Branson of the Virgin Group. This year's theme, "Our Low Carbon Future - Leadership. Opportunity. Security." comes on the heels of President Obama's plans to curb U.S. greenhouse gas emissions and address global climate change.
