[Quantifying the Carbon Reduction Difference Based on Households' Willingness to Transform Their Lifestyles from the Micro Perspective].

Cities are gathering places for residents, industries, and energy consumption, and the carbon emissions generated by urban residents' consumption are becoming increasingly prominent. Under the "dual carbon" goal, how to effectively guide the transformation of urban households' lifestyles and achieve consumption side carbon reduction has become an important issue. Based on questionnaire surveys and face-to-face interviews in the main districts of Hangzhou, the total amount and component of household consumption carbon reduction potential in Hangzhou were calculated by adopting a carbon emission coefficient model, and the relevant factors influencing various types of household consumption behaviors and carbon reduction potential were analyzed through virtual regression models and binary logistic regression. Our results showed that the consumption carbon reduction potential of different groups of residents in the four dimensions of food, clothing, housing, and transportation was significantly different, and electricity consumption had significant direct and indirect impacts on household consumption behaviors and carbon reduction potentials. Age and income were the key factors leading to significant differences in the carbon reduction potential of household consumption. Economic interests and environmental emotional factors were the main factors that affected the transformation of residents' family lifestyle, and their strengths and weaknesses were different. Personal habits, demonstration effects of surrounding people, time costs, etc., were the main reasons affecting residents' willingness to transform their lifestyles. The findings therefore had important implications for climate change mitigation and policy measures associated with lifestyle. On the premise of ensuring stable economic development and improving the well-being of residents, differentiation guides the lifestyle choices of community residents providing reference for better realization of the "double carbon" goal.
