Global Climate Action  

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.

At COP 22 in Marrakech, a High-Level Event on Accelerating Climate Action was held to highlight outcomes from the Action Events throughout the conference and culminated with the launching of the Marrakech Partnership for Global Climate Action; a new framework to catalyse and support climate action.

Emissions reduction


C40 Cities Clean Bus Declaration

Reduce emissions from the transportation sector and improve air quality through the introduction of low and ultimately zero emission buses in fleets


The C40 Clean Bus Declaration is led by the C40 Cities Climate Leadership Group (C40). It is aimed at influencing manufacturers, public transport operators, leasing companies, multilateral development banks and other funding agencies to support city ambitions to decarbonize urban mass transport.

Roadmap and work plan

The cities that are part of the initiative will incorporate over 160,000 buses in their fleet by 2020, of which they have committed to switching 42,000 buses to low emission.


In 2016, two new cities in the African region and three cities in the Latin America and Caribbean (LAC) region have expressed interest in signing up to the Declaration in 2016.
