In terms of actions to address climate change,due to different development stages and industrial structures,countries generally should consider their own interests when they map out their emission reduction plans.The US and the EU,as the two of the most important economies in the world,have taken different emission reduction approaches,with the US forming an emission reduction model dominated by financial incentives,while the EU adopting an emission reduction mechanism centered on carbon pricing.Competition between the two countries in green industry has somewhat intensified Based on the analysis of the historical policies and current main measures of the US and the EU in response to climate change,this article points out the main differences and spillover effects in the climate governance paths between them.However,on issues such as the promotion of emission reduction targets,the governance of trade in steel and aluminum products,and the security of key mineral supply chains,the US and the EU have coordinated through policy dialogue and cooperation mechanisms,and a trend of policy convergence between the two economies is emerging.They have,through legislation,adopt green industrial policies to bind climate goals to industrial resilience,thus constraining China's industrial development.Against the backdrop of the US binding climate governance to industrial competition,trade and national security,China should take active measures to amend its climate policy and green industry development strategy,and respond through diversified global market layout,clean technology innovation and participation in multilateral climate governance.
