摘要
The Glasgow Declaration on Forests signed at the recent UN Climate Change Conference(COP 26)committed to halting forest loss by 2030.141 countries and regions,collectively covering over 90%of global forest,endorsed this declaration.Avoiding forest loss can generally contribute to climate change mitigation;however,the impacts of the declaration on global carbon dioxide(CO_(2))emission reduction are still unclear.Here we show that the Glasgow Declaration,if implemented fully and in a timely fashion,could reduce 123 Gt CO_(2) of emission from 2021 to 2050.This study also highlights that any delays in implementing the declaration would decrease the avoided emission.Although the Glasgow Declaration is a milestone for mitigating climate change,the more ambitious afforestation plan is urgently needed to keep the global temperature rise to below 1.5C relative to pre-industrial levels.
