摘要：

National net zero emission targets could, if fully implemented, reduce best estimates of projected global average temperature increase to 2.0-2.4 degrees C by 2100, bringing the Paris Agreement temperature goal within reach. A total of 131 countries are discussing, have announced or have adopted net zero targets, covering 72% of global emissions. These targets could substantially lower projected warming as compared to currently implemented policies (2.9-3.2 degrees C) or pledges submitted to the Paris Agreement (2.4-2.9 degrees C). Current pledges for emissions cuts are insufficient to meet the Paris Agreement temperature goal. The wave of net zero targets being discussed and adopted could make the Paris goal possible if further countries follow suit.
