This study investigates how our lifestyles can cause societal issue including a reduction in social equity due to the consumption of natural resources. Based on a range of household environmental footprints and their application to a quantitative social equity evaluation framework, a methodology is proposed which identifies the creation and origin of public bads within society. This research builds on the methodologies of energy policy sustainability evaluation incorporated with environmentally extended input output analysis in order to critically assess lifestyle-based consumption impacts, and to quantify the allocation of subsequent burdens across generations. Further, the proposed methodology is applied to a case study in Japan, an aging, shrinking population. Analysis identifies the increasing burden originating with elderly generations, and due to the resolution offered by the methodology, specifically identifies commodities and services which underpin these future burdens, allowing for policy implications to be drawn. The public bads and consumption burden indicator established through the described methodology is proposed as a footprint harmonizing tool to assess sustainability and supplement the footprint family.
