be based on an increased consumption of energy and raw materials but instead must stress greater efficiency and reduced inputs. It should take into account a profound interdependence of North and South in using the earth's resources so as to establish our common future. 47. In order to assure that future generations are provided with natural resources, knowledge, skills and man-made physical capital enabling them to fulfil their needs, it proposed that: Environmental policies, including economic instruments, should be co-ordinated in order to avoid competitive distortions. International agreements should pay special attention · to the environmental impact of trade practices while multilateral banks should integrate sustainable development principles in all their policies. Pricing systems, taxes and incentives for those exploiting natural resources, as well as consumers, should result in care for the environment and be consistent with the "users pay and polluters pay princip les". The accounting of wealth should include the preservation or replacement of natural capital such as forests, water and fertile soil, Furthermore, national accounts should reflect the depreciation of natural assets that accompanies their exploitation and which in some instances deprives future generations of options for development. Countries possessing rich biological diversity need to receive the economic benefits from that diversity so as to provide stronger incentives for their conservation; and Governments and all organizations concerned with environmental awareness must become and act as Green Consumers in their purchasing of environmentally friendly products and recyclable materials. 48, The Joint Agenda emphasized that energy efficiency and conservation must lie at the heart of sustainable energy strategies. It stressed the necessity: To use energy efficiency targets to reduce the consumption of fossil fuels in residential and commerical sectors, and financial means which would result in best available practice and energy standards in ECE countries.
