ABSTRACT
Carbon reduction at the household level is an integral part of carbon mitigation. This study analyses the characteristics, effects, contributing factors and policies for urban household carbon emissions in the Yangtze River Delta of China. Primary data was collected through structured questionnaire surveys in three cities in the region--Nanjing, Ningbo, and Changzhou in 2011. The survey data was first used to estimate the magnitude of household carbon emissions in different urban contexts. It then examined how, and to what extent, each set of demographic, economic, behavioral/cognitive and spatial factors influence carbon emissions at the household level. The average of urban household carbon emissions in the region was estimated to be 5.96 tonnes CO2 in 2010. Energy consumption, daily commuting, garbage disposal and long-distance travel accounted for 51.2%, 21.3%, 16.0% and 11.5% of the total emission, respectively. Regulating rapidly growing car-holdings of urban households, stabilizing population growth, and transiting residents' low-carbon awareness to household behavior in energy saving and other spheres of consumption in the context of rapid population aging and the growing middle income class are suggested as critical measures for carbon mitigation among urban households in the Yangtze River Delta.

Mentions: The study conducted surveys in the three cities under study to collect specially tailored data related to the primary questions. A stratified random sampling method was used to select the residential communities in each surveyed city. Selection criteria considered different contexts of urban communities and households: urban land use, distribution and density of industrial sectors and population, geographical location, household income and the year housing was built (Table 1). As a result, four residential communities in Nanjing and Ningbo respectively, and six communities in Changzhou were selected as representative (Fig. 2). Due to the fact that the numbers of residential communities and residents in the central business district (CBD) of Nanjing are very small, residential communities there were not included in the survey.
