Households significantly influence the sustainability of our planet. ?The decisions individuals and families make in their daily lives can ?have a substantial impact on the environment and society. Traditional ?economic models typically focus on maximizing benefits within one unit ?and one lifecycle, often overlooking the needs of other units and ?future generations. Household sustainability is a new research field ?that seeks to understand how households make choices that affect the ?environment, social well-being, and financial stability, as well as ?how households respond to interventions from these three perspectives. ?This field acknowledges the complex interactions between these three ?dimensions and aims to help households maximize their current utility ?without jeopardizing the utility of future generations. Within ?existing economic frameworks, household sustainability considers two ?additional fundamental issues: concerns for long-term growth (for ?descendants), and constraints placed on human societies.
