This report demonstrates that changes in consump tion patterns and dominant lifestyles are a crit ical and integral part of the solutions package to addressing climate change. However, so far, limit ed efforts have been made in the scientific literature and policy approaches to show the potential contribution that changes in lifestyles could make in keeping global warming within the limit of 1.5 °C as in the aspirational target of the Paris Agreement.
The study conducted for this report is one attempt to fill that gap, and to begin to propose clear targets and quantifiable benefits to climate change solutions by making changes in our lifestyles. The results of the analysis are striking, showing in some cases the need for reductions of over 80% in greenhouse gas emissions (GHG) by 2050 from today’s intensity of lifestyles. Reductions will be necessary not only for industrialised countries; several industrialising countries will also need to reduce average per capita emissions from current levels – a significant challenge where basic needs of large parts of their populations are often not met yet. However, as also identified in the report, there are clear opportunities for much needed changes, and these would require that actions start as soon as possible.
