This year marks the 80th anniversary of the founding of the United Nations, a time to reflect on eight decades of peace, development and human rights. Yet the world also faces urgent challenges, with climate change at the top of the agenda and stronger international cooperation needed more than ever. In this edition of The Hub, Wang Guan sat down with Selwin Charles Hart, special adviser to the UN secretary-general on Climate Action and Just Transition. The discussion looks at the meaning of "Better Together" for the UN at 80, the UN's achievements and future role in global climate governance, and how the Global Governance Initiative can align with the UN Sustainable Development Goals.
