Résumé

Hydrofluorocarbons (HFCs), mainly produced and used in China, are potent greenhouse gases that contribute substantially to climate change, but the benefits of regulating them under the Kigali Amendment (KA) remain underexplored. Here, we report an integrated assessment of how China’s implementation of the KA could influence future HFC emissions and associated climate impacts. The results show that China’s compliance reverses the historical growth of HFC emissions, cutting 18.9 Gt CO2-equiv cumulatively by 2060. This reduction could lower the global mean surface temperature by over 0.03°C at its peak this century and avoid a cumulative US$7.93 trillion in global economic losses, including US$1.59 trillion in benefits for China. Health and agricultural sectors would receive over 90% of the climate benefits from reduced HFC emissions due to lower heat-related mortality and improved agricultural productivity, respectively. The findings emphasize the KA’s indispensable role in China’s climate strategy and global climate resilience.
