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.
Apart from the much-debated question of what legal form the 2015 climate agreement is supposed to have, another core issue is the substantive content of countries' commitments. While the climate regime has so far mostly been based on emission targets, literature has identified a broad range of other possible types of mitigation commitments, such as technology targets, emission price commitments, or commitments to specific policies and measures (PAMs). The nationally appropriate mitigation actions (NAMAs) submitted by developing countries under the Cancún Agreements also show a broad range of different forms of participation. This article surveys the possible commitment types that have so far been discussed in literature and in the UNFCCC negotiations and assesses their respective advantages and disadvantages against a set of criteria: environmental effectiveness, cost effectiveness, distributional aspects and institutional feasibility. The article finds that no commitment option provides a silver bullet. All options have several advantages but also disadvantages. The environmentally most effective way forward may lie in pursuing a multi-dimensional approach, combining emission targets with other commitment types to compensate for the drawbacks of the emission-based approach. However, such an approach would also increase complexity, both in terms of the negotiations and in terms of implementation and administration.
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.
Global climate
(2013)
The eighteenth Conference of the Parties (COP 18) to the United Nations Framework Convention on Climate Change (UNFCCC) and the ninth Conference of Parties serving as the Meeting of the Parties to the Kyoto Protocol (CMP 8) came to a close in the evening of 8 December 2012. This report lays out the main developments in Doha and assesses the main outcomes. The first chapter outlines the overall situation coming into Doha. The subsequent chapters cover the negotiations on the future of the Kyoto Protocol, the discussions under the Durban Platform on developing a new comprehensive climate agreement by 2015 and increasing short-term ambition, and further near-term action under the UNFCCC.
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.
Calculating MIPS 2.0
(2013)
The Wuppertal Institute developed, in the early 1990s, an input-oriented lifecycle-wide resource accounting method, the "Material Input per Service-Unit" concept (MIPS), today also referred to as "Material Footprint". The official handbook applicable to products, services, and processes describes a MS Excel-based sequential approach for calculating MIPS. Today's computing power, available to every researcher, and access to software and databases dedicated to lifecycle analysis make calculating MIPS using matrix inversion possible. This also opens up possibilities for enhancing MIPS-models programmatically: parameterizing the foreground and background systems, batch modeling for producing time series, and computational algorithms enhancing interpretation. The article provides (1) an overview of the methods and tools used for calculating MIPS from its origins to today, and (2) demonstrates some of the programmatically enhanced capabilities offered to MIPS-practitioners.
Several studies in Germany aimed at the development of a sound database on existing waste prevention measures by public bodies at the local, regional and federal levels. These results are the starting point for the creation of a national prevention program, which has to be presented by all European Member States until the end of 2013 - due to the revised European Waste Framework Directive. Based on this empirical foundation, this paper draws conclusions with regard to drivers and barriers for eco-innovations in the field of waste prevention. The analysis shows that an optimized adaptation of information on waste prevention to the needs of specific target groups is still missing but could be a relevant driver. With regard to barriers the results of the study show that waste prevention is by no means always a win–win-situation. Institutional frameworks are missing to coordinate the different interests and for the exchange of experiences that could help to realize learning effects regarding innovation approaches.
Resource use of wind farms in the German North Sea : the example of Alpha Ventus and Bard Offshore I
(2013)
The German government aims to obtain at least 40 percent of its electricity from renewable sources by 2030. One of the central steps to reach this target is the construction of deep sea offshore wind farms. The paper presents a material intensity analysis of the offshore wind farms "Alpha Ventus" and "Bard Offshore I" under consideration of the grid connection. An additional onshore scenario is considered for comparison. The results show that offshore wind farms have higher resource consumption than onshore farms. In general, and in respect to the resource use of other energy systems, both can be tagged as resource efficient.
The article argues for a need to overcome a conventional notion of product design. In this regard, the article offers an integrative and systemic approach to sustainable design. Instead of focusing on objects, a user-centred perspective is adopted. A sustainable design of products and services requires the integration of production-orientated (efficiency and consistency) and consumption-orientated (sufficiency) strategies. The article introduces the concept of an indicator that is capable of comprehending a lifecycle-wide analysis of products and that favours the integration of existing sustainability strategies. The goal is not to design sustainable products but rather to design systems that manage to foster sustainable lifestyles. The article illustrates the usability of the introduced concept by showing examples of strategic integrative thinking in sustainable design from the Sustainable Summer Schools.
The Durban Climate Conference agreed on the creation of a new market-based mechanism under the United Nations Framework Convention on Climate Change (UNFCCC) and to consider the establishment of an overall framework for various mitigation approaches, including opportunities for using markets ("Framework"). The creation of such a Framework is therefore of high political significance, as it should ensure on the one hand that new market-based mechanisms contribute to global climate change mitigation and to achievement of targets, and on the other hand, that different market-based approaches can be integrated in a global carbon market. As yet, there is little clarity as to the roles and design of such a framework. This paper contributes to the debate by discussing and evaluating inter alia several design options, and explores how the various options could be implemented and how they interrelate. It concludes that a strong central oversight at the level of the UNFCCC is probably the only option that could reassure the vast majority of UNFCCC Parties that the environmental integrity of new market-based mechanisms is in fact ensured. This does, however, not exclude that some reasonable balance may be struck between centralization and flexibility.
