“Reason doesn’t mean very much in a country like North Korea.”

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

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 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.

Planet Earth is our shared island, let us join forces to protect it

On this International Day, let us promise to make peace not just a priority, but a passion. Let us pledge to do more, wherever we are in whatever way we can, to make every day a day of peace.

I am not a national leader. If I am a national leader I can speak out all that I want.

Saving our planet, lifting people out of poverty, advancing economic growth… these are one and the same fight. We must connect the dots between climate change, water scarcity, energy shortages, global health, food security and women’s empowerment. Solutions to one problem must be solutions for all.

We must follow the wisdom of the Brundtland Report. We must pursue development that meets the needs of the present generation without compromising the ability of future generations to meet their needs.

On this International Day for the Abolition of Slavery let us reaffirm the inherent dignity of all men, women and children. And let us redouble our efforts to build societies in which slavery truly is a term for the history books.

Extreme weather events continue to grow more frequent and intense in rich and poor countries alike, not only devastating lives, but also infrastructure, institutions, and budgets – an unholy brew which can create dangerous security vacuums.

The clear and present danger of climate change means we cannot burn our way to prosperity. We already rely too heavily on fossil fuels. We need to find a new, sustainable path to the future we want. We need a clean industrial revolution.

One of my earliest memories is walking up a muddy road into the mountains. It was raining. Behind me, my village was burning. When there was school, it was under a tree. Then the United Nations came. They fed me, my family, my community.

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.

It has been said that knowledge is power. We need to strengthen education systems so that young people can benefit from cultural diversity, and not be victimized by those who exploit differences.

Sustainable development and climate change are two sides of the same coin

I call on men and boys everywhere to join us. Violence against women and girls will not be eradicated until all of us – men and boys – refuse to tolerate it.
