In a German case study, environmental input-output analyses (eIOA) combined with NAMEA-type tables were conducted for eleven selected environmental pressure variables. (NAMEA is an acronym for national accounts matrix including environmental accounts.) The analyses were conducted to derive the production-cycle-wide resource use and environmental impact potentials of final-demand product groups. The methodology permits identification and preliminary ranking of 10 product chains along which about two-thirds of German production-born environmental pressures arise. The most relevant product groups are construction work, food, motor vehicles, basic metals, and electricity. The ten product groups are characterized by both high resource requirements and high residual outputs (air emissions, wastes). The EU policy areas of integrated product policy and sustainable use of natural resources may address these product chains as a priority in order to identify and explore the possibility of reducing the environmental impacts from products throughout their life cycles and to decouple environmental impacts from resource use.
Policies for Sustainable Use and economy-wide Management of natural Resources (SUMR) throughout the production and consumption system are faced with environmental and socio-economic requirements and regulatory constraints. Based on empirical findings of ongoing trends of resource use, decoupling from economic growth, and transregional problem shifting, the paper outlines a potentially sustainable biophysical basis for production and consumption in the EU. It discusses the main challenges for the major resource groups, describing the specific and the common tasks with regard to biomass, fossil fuels, metals, non-metallic minerals. Adopting a medical metaphor, it suggests that policies for SUMR should follow a dual approach reflecting the long-term need for a main cure of the socio-industrial metabolism in form of a "conditioning" towards a more mature, resource efficient, and renewables based constitution on the one hand, and a fine tuning of selected material flows (e.g. for optimized recycling and control of hazardous compounds) on the other hand. Both strategies are deemed complementary and necessary to reduce environmental impacts and increase the utility of material use. Action required is exemplified with regard to the three pillars of SUMR, i.e. improved orientation, information and incentives.
The book contains the proceedings of INFER annual conference 2004, organized at the Wuppertal Institute in Germany. Within the area of environmental economics, methodological issues now seem at stake. This is because recent methods and fields of economics, like institutional economics, competition (industrial) economics, and cognitive economics, should be applied and become more established within environmental economics. The different papers address this challenge via different case studies in areas such as agriculture, biodiversity, eco-taxes, subsidies, wind energy, environmental corruption, governance, contracts, international trade, human behavior, and many others.
