Adopted at the spring 2016 session of the UN System Chief Executives Board,  the "Common Core Principles for a UN System-wide Approach to Climate Action" draw on successful examples of previous and current UN system-wide approaches to climate change, as well as identified gaps and opportunities for system-wide action for more effective support to Member States. The principles have been designed to guide a system-wide approach and inform and strengthen the system’s collective support to climate change action under the 2030 Agenda for Sustainable Development, the UNFCCC process, and the implementation of the Paris Agreement at the global, regional and national and sub-national level.
