Abstract: Carbon emissions caused by urban residential sector have attracted increasing attention due to the rapid urbanisation. Choosing Tianjin as a typical example, this paper analysed the factors causing carbon emissions in urban residential sector. Based on the extended Kaya identity, a multivariate generalised Fisher index (GFI) decomposition model was built to measure the impacts of energy structure, energy intensity, per capita disposable income, household size and number of households on urban residential carbon emissions from 1995 to 2014 in Tianjin. The results show that sustained growth of per capita disposable income was the leading factor of the urban residential carbon emissions in Tianjin, with cumulative contributions of 639.1% in 2014 compared to that in 1995. The number of households had a stimulating effect on the growth of carbon emissions in the same period. The continuous optimisation of the energy structure over the past 20 years had no obvious inhibitory effect on carbon emissions. Energy intensity was the primary factor restraining carbon emissions with the cumulative contributions of 0.318. To a certain extent, household size reduced carbon emissions but only with a slight effect.
