Given the significant contribution of households in terms of energy use and greenhouse gas (GHG) emissions, in addition to the increasing rate of urbanization and growth in developing countries, urban dwellings need to be analyzed in greater depth in order to implement sound policy-making based on informed decisions. Thus, the aim of this study is to quantify the household-related energy use and associated GHG emissions in the city of Lima, Peru, between 2007 and 2015. In order to understand the emission patterns within the city, a further analysis on smaller spatial scales (i.e., districts) has been performed using multiple regression analyses. Results show that household-related energy consumption and emissions, excluding those related to private vehicles, ranged from 2.92 to 3.22 GJ/cap/year and 187 to 249 kg CO2eq/cap/year, respectively. Overall, there is a transition in the use of energy and emissions, sustained by an increase in population and a change in the economic status of part of the population. Moreover, liquefied petroleum gas, rather than electricity, was found to be the main energy source in lower-income households. This study aims to help integrate household energy behavior with strategies for sustainable cities and provide a starting point to connect with climate policies.
