National net zero emission targets could, if fully implemented, reduce best estimates of projected global average temperature increase to 2.0–2.4 °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.
Currently implemented policies will increase warming by 2.9–3.2 °C, and pledges submitted to the Paris Agreement will increase warming by 2.4–2.9 °C.
