Organisers behind the Global Goals initiative are launching a worldwide campaign to combat poverty, inequality, injustice and climate change, and have enlisted the stars along with Robert Pattinson, Ashton Kutcher, Meryl Streep and others to spread the message through various media platforms.

A statement about the campaign reads, "If the goals are famous - if people care about what has been promised by the politicians, it greatly increases their chance of being implemented. So today the campaign along with the UN is calling on everyone to help make the goals famous and ensure they become a reality."

On 26 September (15), Beyonce, Ed Sheeran, Coldplay, and Pearl Jam, will perform in Central Park in New York on September 26 for the Global Citizen Festival to further boost awareness about the initiative.
