Dear Friends,

From Paris – the city of light – a new light now shines bright for the future of our planet and the future of the human family.

Despite their many differences, the nations of the world have ushered in a new era of global cooperation on climate change, one of the most complex issues ever to confront humanity.

We would not have achieved this victory without the leadership and vision of civil society. You have highlighted both the stakes and the solutions to the climate challenge. From young activists to artists, faith leaders to business leaders, mayors to mothers, all of society has come together under one banner and brought forth this moment of hope.

I wish to express a special thanks to the young people in every corner of the globe who have raised their voices, mobilized on social media, marched in the streets, and demanded change from their governments. I encourage you to continue your impassioned leadership. Make the climate a priority in your choices as a consumer, investor and citizen and urge others to do the same. Reconnect with nature. Reach out and bring others on board. And keep Governments accountable for their Paris pledges.

Our planet needs you now more than ever. With your help, we can create a safer, more peaceful and livable world for all.

United Nations Secretary-General Ban Ki-moon
