The change of people’s lifestyle is the key to mitigating climate change. This report focuses on the low carbon consumption of urban residents. Based on the questionnaire data，survey experimental data and big data，it analyzes the current situation，existing problems and impact mechanism of low carbon consumption. In terms of attitude，urban residents generally have a positive attitude towards low-carbon consumption，strong recognition of low-carbon culture，and strong sense of individual responsibility. However，they are also concerned that low-carbon consumption will affect their quality of life，and also worried that low carbon economy will affect employment and income. In terms of behavior，low carbon purchase is more common，while the proportion of low carbon use and disposal is lower. Two key areas of low carbon consumption，i.e.，second-hand consumption and traffic consumption，are also investigated. The analysis of consumption behavior in different fields all points to the important role of the external material and cultural environment in promoting low-carbon consumption. The improvement of the market supply system，the standardization of the market，the diversified consumption structure，and the green accessibility of daily consumption are the key factors for residents to practice low-carbon consumption. The analysis also points out that we should pay attention to middle-income groups and young people，who play an important role in shaping social and cultural environment. Based on empirical analysis，this report proposes measures and suggestions to promote low-carbon lifestyle from the framework of social governance，social innovation and social culture.
