In the packaging industry, where customer behaviours at the end of life are critical to the success of environmentally friendly plans, the incorporation of customer behavioural data is particularly pertinent. To improve the analysis and creation of environmentally friendly packaging, this research investigation investigates the integration of behavioural insights from customer behaviour sciences (such as psychology, sociology, and socio-technical techniques) into life cycle assessment (LCA). The findings show that research on LCA on packaging is typically predicated on theories about customer behaviour, which lessens the usefulness of these studies to assist with sustainable decisions. Nowadays, scenario and sensitivity analysis are the primary techniques used to incorporate behaviour variability. Two key areas in which customer behaviour sciences insights might benefit life cycle assessment (LCA) research are the definition of customer profiles and the modelling of socio-technical characteristics.
