Abstract: By using methods of carbon footprint, and impacts of population, affluence and technology (IPAT), the article analyzed the carbon footprints of residential livings and travel and their influential factors under different urban residential incomes, on the basis of conducting 1500 household questionnaires in Shijiazhuang City, Hebei Province. The results show that the process in which urban residents improve their living standards is also the one to push carbon footprints growing; at the same time, the progress in technology has a positive impact on reducing the carbon footprints of urban residential livings. Thus, the article suggests that some measures, such as promoting energy-saving buildings and central heating supply, and establishing the convenient and comfortable public transport system, should be taken to cut down the carbon footprints of residential livings and travel.
