It also discusses how the FD2018 could encourage further climate action and support for developing countries through both political and technical dialogues. The document outlines potential inputs, such as IPCC and UNFCCC reports, and expected outputs focused on increasing pre-2020 climate ambition and informing the 2020 round of updated NDCs.
