Abstract: Energy saving and carbon reduction are crucial to global climate change mitigation. As the economic developments of countries and regions are of great difference, energy and emission intensities, which have drawn wide public attention, become significant indexes to measure energy saving and carbon reduction. On the basis of production-side intensity control, how to fundamentally curb the aggregate embodied energy and emission intensities from the consumption side has attracted increasing attention. Thus, this study conducted a literature review on consumption-side intensities. It is found that: (1) Studies at national level are dominating, those at global level increase significantly, and those at provincial and city levels have begun to emerge. In particular, the studies at national, provincial, and city levels are chiefly about China. (2) Compared with aggregate embodied energy intensity, aggregate embodied emission intensity has received greater attention. (3) Existing studies on consumption-side intensities extend from indistinguishable final demands to distinguishable final demands, while those embodied in exports attract hot discussions. (4) Some scholars focus on local areas, such as economic sectors which heavily participate in global production networks, as well as the critical transmission layers of energy consumption and carbon emissions within the production network. (5) The temporal and spatial determinants of consumption-side intensities are measured by multiplicative structural decomposition analysis. The current framework can be extended to other indicators related to energy and environmental fields in the future.
