摘要
Since the adoption of the Paris Agreement, almost all countries have submitted their nationally determined contributions (NDCs) to the United Nations Framework Convention on Climate Change (UNFCCC) secretariat. Those submissions form the basis for the implementation of Paris Agreement. However, recent research [1] has shown that existing NDCs will not bring the world to the goal of limiting global temperature increase to below 2 °C above preindustrial levels, much less achieving the goal of limiting warming to 1.5 °C [2,3].
