As the young leaders of tomorrow, you have the passion and energy and commitment to make a difference. What I'd like to really urge you do is to have a global vision. Go beyond your country; go beyond your national boundaries

Since [violence against women] is rooted in discrimination, impunity and complacency, we need to change attitudes and behavior - and we need to change laws and make sure they are enforced just like you are doing in Cuba.

You have to work and think about how we can make this world a better place for all. This is what I'd really like to ask our young leaders. We will try as leaders of today to minimise the problems which we will hand over to you. But it is to you. You have to take ownership and leadership of tomorrow. For that to be possible, you have to strengthen your capacity and widen your vision as a global citizen.

Climate change has happened because of human behaviour, therefore it’s only natural it should be us, human beings, to address this issue. It may not be too late if we take decisive actions today.

Sustainable development is the pathway to the future we want for all. It offers a framework to generate economic growth, achieve social justice, exercise environmental stewardship and strengthen governance.

Climate change does not respect border; it does not respect who you are - rich and poor, small and big. Therefore, this is what we call global challenges, which require global solidarity.

Gender equality and women's empowerment have been a top priority for me from day one as Secretary-General. And I am committed to making sure that the U.N. leads by example.
