We must turn the greatest collective challenge facing humankind today – climate change – into the greatest opportunity for common progress towards a sustainable future.

As many micro-credit schemes across the world can testify, investment in women is the best investment for the future.

Climate change...is, simply, the greatest collective challenge we face as a human family.

Saving our planet requires you to be ambitious in what you aim, and, equally, in how hard you work to reach your goal.

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

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.

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.
