”A key requirement for the success of any such strategy [IPPC] is to ensure that people are still able to live a ‘decent’ life. … That requirement includes people's capabilities not only to provide food and shelter for themselves and their families but also to participate effectively in the life of society.”
Druckman & Jackson 2010Ecological Economics (69), 1794-1804

• Half of the present average still ensures a decent life – but is still appr. factor 3 over sustainable level
• There is a connection between income and material footprint.
• Households cannot achieve sustainability alone. Governments and companies are needed to improve conditions and develop new innovations.

• Ongoing: calculation of the material footprint of 18 low-income households in real life, based on questionnaires and interviews.
• Preliminary results will be presented at the World Resources Forum in Davos in September 2011.
