"To reduce humanity's environmental footprint toward a sustainable level, it is necessary to reach consensus on footprint caps at different scales, from global to national or river-basin scale. Footprint caps need to be related to both production and consumption (32<http://www.sciencemag.org/content/344/6188/1114.full#ref-32>, 55<http://www.sciencemag.org/content/344/6188/1114.full#ref-55>). The various components of the environmental footprint of humanity must be reduced to remain within planetary boundaries. Improved technologies (eco-efficiency) alone will not be sufficient to reach this goal; consumption patterns will need to alter as well (39<http://www.sciencemag.org/content/344/6188/1114.full#ref-39>). How such cultural shift and transformative change in the global economy could take place remains an open question. It is clear, however, that such change will profoundly affect all sectors of the economy. There are always several entities playing a role in causing a footprint: the investors, the suppliers, the recipients, and the regulators. Hence, the responsibility for moving toward a sustainable footprint is to be shared among them (32<http://www.sciencemag.org/content/344/6188/1114.full#ref-32>, 56<http://www.sciencemag.org/content/344/6188/1114.full#ref-56>). The way societies and economies have institutionalized responsibility is clearly insufficient to warrant environmental sustainability, eco-efficiency, fair sharing, and long-term resource security. Exploring how we can better institutionalize full supply-chain responsibility is one of humanity's major research challenges toward achieving a sustainable future." Good luck!
