How does material efficiency create value for businesses?

What do the following key material efficiency strategies mean concretely for business models: more intensive use, lifetime extension, material substitution, better recycling and efficient design?

How can the buildings and mobility sectors implement more intensive use strategies for existing housing and vehicles?

What are key policy incentives for “more intensive use” and other approaches to material efficiency?

On 2 February (2pm CET), join the GGKP, Ellen MacArthur Foundation, International Resource Panel (IRP), World Economic Forum (WEF) and the United Nations Environment Programme (UNEP) for a discussion on how to put "more intensive use" strategies into practice in the housing and mobility sectors. 

This webinar will also serve as the launch of "Implications for Business Leaders," an addition to the recent IRP report Resource Efficiency and Climate Change: Material Efficiency Strategies for a Low-Carbon Future.
