There is some evidence to support these claims but this line of research should be deepened. Thus, to ensure that these benefits are realised, the design of resource efficiency policies should be guided by an assessment of their costs and benefits, particularly when establishing objectives and targets. The G7 can play an important role in this respect, including by supporting businesses in their supply chain management efforts, addressing trade and investment related obstacles, using official development assistance to support resource efficiency efforts, and improving environmental labelling and information schemes, as well as resource efficiency data and indicators more broadly.
