In recent years，governments，states and provinces，cities，investors，companies，and the public have all taken vigorous actions to reduce emissions，and the global response to climate change has made positive progress. The outbreak of the epidemic crisis in 2020 is an early warning of how climate crises and natural disasters will threaten the global economy and society. It has also tested the governance capabilities and climate determination of governments. Historical experience has shown that with technological progress and the cost increase in reducing greenhouse gas emissions，adopting a strong climate policy can better achieve economic recovery and strengthen economic resilience. The current round of the epidemic crisis provides an opportunity for the world to accelerate the transition to an energy-friendly future. The European Union，China，South Korea，etc. are all staunch supporters of green development，providing support for the green recovery of the economy after the epidemic in terms of policy design and financial investment. Whether the world can take more ambitious actions in the future is not only affected by short-term factors such as the duration of the epidemic，economic recovery patterns，and whether countries adopt green stimulus plans，but also by long-term factors such as whether sufficient resources can be mobilized to slove the climate financing bottleneck，whether key clean technologies such as battery storage carbon capture and storage and hydrogen energy can make a breakthrough，and whether the emission reduction potential of local governments，the private sector and other non-governmental actors can be fully stimulated.
