12 August 2015 – Marking International Day of Youth， United Nations Secretary-General Ban Ki-moon stressed that no one knows better than young people the issues at stake in today's rapidly changing world or the best way to respond， and declared： “That is why I am calling on young people to speak out – and I am urging leaders to listen.”

As the world changes with unprecedented speed， young people are proving to be invaluable partners who can advance meaningful solutions， the Secretary-General stated in a message issued for the Day， observed each year on 12 August.

“Youth movements and student groups are challenging traditional power structures and advocating a new social contract between States and societies. Young leaders have contributed fresh ideas， taken proactive measures， and mobilized through social media as never before，” said Mr. Ban.

This year's theme – 'Youth Civic Engagement' – emphasizes the involvement and inclusion of young people in building social cohesion and collective well-being， underlined Irina Bokova， Director-General of the UN Educational， Scientific and Cultural Organization （UNESCO）， in her message on the Day.

“From social entrepreneurs to journalists， from voluntary workers to members of community organizations， young people contribute to shaping society to lead it towards political， cultural and economic renewal，” she stressed.

As world leaders prepare to adopt a bold new vision for sustainable development next September， the engagement of youth is more valuable than ever， assured the Secretary-General. “At this critical moment in history， I call on young people to demand and foster the dramatic progress so urgently needed in our world.”
