At the twenty-first session of the Conference of the Parties (COP 21) in Paris, it was agreed that mobilizing stronger and more ambitious climate action by all Parties and non-Party stakeholders is urgently required if the goals of the Paris Agreement are to be achieved. In decision 1/CP.21, the commitments from all actors are recognized, including those launched through the Lima–Paris Action Agenda, as well as the urgent need to scale up the global response to climate change and support greater ambition from governments. To ensure a durable connection between the Convention and the many voluntary and collaborative actions, Parties decided that two high-level champions shall be appointed. The above-mentioned decision details the tasks to be performed by these high-level champions.
