The seventh Secretary-General of the United Nations and One Young World Counsellor, Kofi Annan, calls on world leaders to set an example and deliver a strong and inclusive climate agreement at COP21. Mr. Annan says that they must show the younger generation what we can achieve when we work together. Call On COP is the most global action on Climate Change in 2015. At the One Young World Summit 2015, young leaders from every country in the world addressed their Heads of Government on mainstream media two weeks before the Paris Climate Conference - COP21.Each Call On COP delegate delivered an impactful speech highlighting how climate change is endangering our future. Several One Young World Counsellors also participated in this global campaign, urging for a strong climate agreement in Paris.20 years of UN climate negotiations have been unable to produce a legally binding and universal agreement on Climate Change. The united voice of young leaders can help ensure that governments act to avoid catastrophic Climate Change.
