Since China pledged in September 2020 to peak carbon by 2030 and become carbon neutral by 2060，helping to achieve this target has become a must for Chinese companies to fulfil their environmental responsibilities and a new fulcrum for their green growth. In response to clear policy signals and market pressures，several leading companies have taken the lead in proposing carbon neutrality timetables and road maps，and have launched exploratory actions in key difficult areas. This article aims to systematically analyze the overall response of Chinese enterprises to carbon neutrality，summarize their phased characteristics in implementing targets，show typical actions and excellent business practices，and try to put forward future suggestions on the problems observed at the present stage.
