EXIOPOL (A New Environmental Accounting Framework Using Externality Data and Input–Output Tools for Policy Analysis) was a European Union (EU)-funded project creating a detailed, global, multiregional environmentally extended Supply and Use table (MR EE SUT) of 43 countries, 129 sectors, 80 resources, and 40 emissions. We sourced primary SUT and input–output tables from Eurostat and non-EU statistical offices. We harmonized and detailed them using auxiliary national accounts data and co-efficient matrices. Imports were allocated to countries of exports using United Nations Commodity Trade Statistics Database trade shares. Optimization procedures removed imbalances in these detailing and trade linking steps. Environmental extensions were added from various sources. We calculated the EU footprint of final consumption with resulting MR EE SUT. EU policies focus mainly on energy and carbon footprints. We show that the EU land, water, and material footprint abroad is much more relevant, and should be prioritized in the EU's environmental product and trade policies.
While strategic studies on natural resources usually focus on the criticality of certain single materials, our paper starts from the inter-linkages between and among resources (called "the resource nexus"). It examines the impact any food and water stress may have on extraction activities in fragile states and regions. According to our approach, conflicts are likely to increase and may escalate in a number of countries, many of which are of relevance for the global supply of strategic materials. Future criticality for European and other industries, thus, is more likely to result from particular regions surpassing their adaptive capacities, and not mainly from limited availability or bottlenecks in the supply chain. The paper first develops a heuristic model of drivers for stress in resource-rich regions. Applying this approach, our paper then develops a global three-layered map along the dimensions of (i) future regional food and water stress, (ii) fragility of countries, and (iii) resource-rich countries with relevant reserves of strategic materials. As a result our paper tentatively identifies 15 countries at high risk and some 30 other countries being at relevant risk of causing resource supply disruptions. The conclusions underline the need to analyse those global inter-linkages and institutional mechanisms for strategic futures studies at a regional scale. As this may go beyond the capacities of actors on commodity markets, our paper also draws conclusions towards the establishment of an international data hub on the global resource nexus and for futures research. The paper points to some of the long-term implications of these issues.
Improving material efficiency in the manufacturing industry is a sustainability imperative for companies due to economic and environmental advantages such as the reduction of material costs and resource use. Innovative solutions in terms of material efficiency measures are diverse and widespread. As a systematic assessment of efficiency approaches and their effects are likely to support dissemination and deployment, this paper aims to develop an approach that helps to classify material efficiency measures. The classification approach presents different dimensions and properties of material efficiency measures based on a literature analysis regarding existing classification approaches as well as on work that has been conducted for the Eco-Innovation Observatory. The classification has been designed as basis for an empirical impact assessment of material efficiency measures based on a data sample that stems from the German Material Efficiency Agency.
Based on the European Waste Framework Directive and the German Recycling Management Act of 01.06.2012 the objectives for a national waste prevention programme were defined. As main objective, according to art. 1 WFD, the "prevention or reduction of the disadvantageous impacts of waste generation and management on the human health and the environment" is recommended. Indicators for a quantitative and qualitative monitoring are derived for both, the individual measures as well as for a waste prevention programme.
Carbon recycling, in which organic waste is recycled into chemical feedstock for material production, may provide benefits in resource efficiency and a more cyclical economy - but may also create "trade-offs" in increased impacts elsewhere. We investigate the system-wide environmental burdens and cost associated with carbon recycling routes capable of converting municipal solid waste (MSW) by gasification and Fischer-Tropsch synthesis into ethylene. Results are compared to business-as-usual (BAU) cases in which ethylene is derived from fossil resources and waste is either landfilled with methane and energy recovery (BAU#1) or incinerated (BAU#2) with energy recovery. Monte Carlo and sensitivity analysis is used to assess uncertainties of the results. Results indicate that carbon recycling may lead to a reduction in cumulative energy demand (CED), total material requirement (TMR), and acidification, when compared to BAU#1. Global warming potential is found to be similar or slightly lower than BAU#1 and BAU#2. In comparison to BAU#2, carbon recycling results in higher CED, TMR, acidification, and smog potential, mainly as a result of larger (fossil-based) energy offsets from energy recovery. However, if a renewable power mix (envisioned for the future) is assumed to be offset, BAU#2 impacts may be similar or higher than carbon recycling routes. Production cost per kilogram (kg) MSW-derived ethylene range between US$1.85 and US$2.06 (Jan 2011 US$). This compares to US$1.17 per kg for fossil-based ethylene. Waste-derived ethylene breaks even with its fossil-based counterpart at a tipping fee of roughly US$42 per metric ton of waste feedstock.
