This report focuses on the contribution of ICT to improvements in resource efficiency and transport intensity at the macro, meso and micro levels. It presents the research on environmental effects of e-business and e-work. The research strand explored the implication of ICT and its applications from the micro- (case study), meso- (different e-business types) and macro-level (macro-economic and policy level). The "macro-analysis-module" aimed at quantifying the potential contribution of e-business and ICT to dematerialisation and resource productivity. The analysis followed a top-down approach complementary to the case study based microanalyses. It compromised the analysis of energy-use and selected material flows (CO(2)) of three EU Member States to determine whether there is any macro-level evidence of dematerialization and increased resource productivity resulting from e-business and ICT. From a micro and meso level perspective, the research object has been the provision of new IT based applications instead of "traditional" products, services and customs (e-commerce and telework). The research quantified the resource- and transport efficiency of e-business in different case studies and identified key factors determining the impact on resource- and transport efficiency.

Resource flows constitute the materials basis of the economy. At the same time, they carry and induce an environmental burden associated with resource extraction and the subsequent material flows and stocks, which finally end up as waste and emissions. A reduction of this material throughput and the related impacts would require a reduction of resource inputs. And breaking the link between resource consumption and economicgrowth would require an increase in resource productivity. Material flow analysis (MFA) can be used to quantify resource flows and indicate resource productivity. In this article, we study the available empirical evidence on the actual (de-)linkage of material resource use and economic growth. We compare resource use with respect to total material requirement (TMR) and direct material input (DMI) for 11 and 26 countries, respectively, and the European Union (EU-15). The dynamics of TMR, as well as of the main components are analysed in relation to economic growth in order to show whether there is a decoupling (relative or absolute) from GDP and a change of the metabolic structure in the course of economicdevelopment. DMI/cap so far only decoupled from GDP/cap in relative terms; that is, in most countries, it reached a rather constant level but - with the exception of Czech Republic - showed no absolute decline yet. TMR/cap was reduced in two high-income countries and one low-income country due to political influence. Changes in TMR were more influenced by hidden flows (HF) than by DMI. We analyse the dynamics of the structure and composition of TMR in the course of economic development. In general, the economic development of industrial countries was accompanied by a shift from domestic to foreign resource extraction. Different relations can be discovered for the share of biomass, fossil fuel resources, construction resources and metals and industrial minerals.

Angesichts der hohen Kostenrelevanz sollte es selbstverständlich sein, die Ressourcenproduktivität zu erhöhen. Eine europaweite Studie zeigt, dass ein effizienterer Einsatz von natürlichen Ressourcen und Material auch Wettbewerbsvorteile bringt.
