At the COP 21 United Nations climate change conference in Paris, governments agreed that mobilizing stronger and more ambitious climate action is urgently required to achieve the goals of the Paris Agreement. To connect the work of governments with the many voluntary and collaborative actions taken by cities, regions, businesses and investors, nations decided to appoint two Climate Change High-Level Champions. The champions work focuses on two crucial areas: 1. Engage with interested Parties and non-Party stakeholders: This work builds on existing initiatives and supports new and more geographically diverse initiatives. Focus is placed on connecting initiatives and coalitions with national action plans such as nationally determined contributions (NDCs) to the Paris Agreement. This helps bringing more transparency, with result tracking and lends demonstrable credibility to climate action. 2. Input from the champions efforts to mobilize action helps the secretariat organize technical expert meetings and, in collaboration with the Executive Secretary and the current and incoming Presidents of the Conference of the Parties, coordinate annual high-level events to spur even greater ambition and action.
