Since 2015，China’s sustainable development index has steadily improved，the economic development index has made stable progress，the social livelihood index has continued to improve，the consumption and emission index has further increased，and the resource and environmental index and governance and protection index have shown a trend of upward trend. However，the last two indexes have fallen back recently due to some complex factors such as the impact of the epidemic and climate change. In the critical period of China’s economic transformation and development，the problem of unbalanced and inadequate development among economy，society and environment has become increasingly prominent. It is increasingly difficult to coordinate environmental protection，low-carbon transformation，and sustainable growth. There are still many shortcomings and weaknesses in the field of people’s livelihood and it is difficult to achieve the carbon peaking and carbon neutrality goal as scheduled. There is still a long way to go for promoting China’s sustainable development. It is necessary to further comprehensively deepen reforms around the promotion of Chinese-style modernization，make greater efforts to promote carbon and pollution reduction，green expansion and development，reasonable economic growth，people’s livelihood improvement，as well as resources conservation，ecological governance，environment protection，and gradually reduce pollutant emissions and greenhouse gas emissions.
