I spend most of my time in South Korea but at least one-third of my time is spent traveling around the world, meeting people, speaking about climate change and sustainable development and trying to foster global citizenship especially for young people. What I observe is there clearly is a need for global citizenship. That is exactly right. We are having troubles around the world. We need global vision.

Saving our planet, lifting people out of poverty, advancing economic growth – these are one and the same fight.

Let us acknowledge and celebrate what youth can do to build a safer, more just world. Let us strengthen our efforts to include young people in policies, programmes and decision-making processes that benefit their futures and ours.

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.

The power of the leader is given to him by the people, so he has a duty to engage and listen more attentively and carefully to the aspirations of the people.

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.

The basic building block of peace and security for all peoples is economic and social security, anchored in sustainable development. It is a key to all problems. Why? Because it allows us to address all the great issues-poverty, climate, environment and political stability-as parts of the whole.
