Low-carbon consumption culture provides correct guidance for the development of low-carbon consumption，serves as the driving force for promoting supply-side structural reforms，and guides people’s high-quality life. The construction of a high-quality living circle in the Guangdong-Hong Kong-Macao Greater Bay Area inevitably requires taking the path of low-carbon economy，and low-carbon consumption is the most direct manifestation. To promote the development of low-carbon consumption，the most important aspect is the change of people’s consumption concept，and the core lies in strengthening the construction of consumption culture，leading the practice of low-carbon consumption with consumption culture. The low-carbon consumption in the Guangdong-Hong Kong-Macao Greater Bay Area is still on the left side of the inverted U-shaped curve，and it is necessary to further deepen understanding，improve laws and regulations，strengthen technological innovation，enhance the supply capacity of low-carbon products，form a carbon footprint standard in the Greater Bay Area，and improve low-carbon consumption incentive and constraint mechanisms to promote low-carbon consumption practice.
