The circle is a ubiquitous metaphor in the current scientific and political debate on possible strategies for coping with the changes brought by the so-called "Anthropocene". Terms such as "recycling", "upcycling", "downcycling", "life cycle" or "circular economy" all refer to the same geometric shape, which in turn can be found in numerous diagrams illustrating the respective design approaches and political strategies. But how does the circle shape the way we think and act as designers? Is it an appropriate metaphor to guide us to feasible actions, or is its degree of simplification too far removed from reality? In this article we look at the circular economy as a designed model, and question the circle as a communication tool for the cultural project of sustainability. As the circle may carry the risk of an oversimplified, unattainable, even disillusioning ideal, we discuss various alternative images and forms for their potential to become metaphors of alternative models. The hole, the plate, the pasture, the wheel, the mill wheel, the hamster wheel, the vortex, the double helix, the spider web and the rhizome - as metaphors, they each open up different perspectives and approaches to reality, they each construct different relationships and dependencies between nature and culture. The aim of this article is less about postulating the end of the circle as a metaphor in the sustainability debate, as it is about to fathom the circle's ends as a metaphorical tool. In other words, when does the metaphor of the circle become too abstract? As designers we can say that falling in love with a form right at the beginning of a design process can be rather limiting, as hardly any alternatives will be considered, and all further decisions are subordinated to achieving the desired shape. Therefore, we would like to emphasise the contingency of the circular economy as a model. We would like to welcome the thought that the circle has an "end".
The ultimate goal of German Resource Efficiency Programme (ProgRess) is to make the extraction and use of natural resources more sustainable and reduce associated environmental pollution as much as possible. By doing this - also with responsibility towards future generations - the programme should create a prerequisite for securing a long-term high quality of life. To bring the policy approaches formulated in ProgRess to reality, efforts to implement resource efficiency measures have to be increased at all levels - from international to regional to local.
The chapter intends to provide an impetus for the current debate on ProgRess policy development. The chapter identifies, analyses and describes deficits and possibilities of vertical integration of the German programme in particular and derives recommendations for action which may also serve as indications for other strategies. The following sections are based on results of the advisory report "Vertical integration of the national resource efficiency programme ProgRess (VertRess)", conducted by the German Institute of Urban Affairs (Difu) and the Wuppertal Institute for Climate, Environment and Energy on behalf of the German Environmental Agency (UBA) and the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (BMU).
This article presents an account of how deeply entrenched the neoclassical economic paradigm with its homo economicus and unlimited growth ideals has become in our societies and why this inhibits solutions for sustainable futures. Drawing on political economists like Karl Polanyi and Antonio Gramsci it also highlights how the current questioning of this paradigm and thus informed mindsets provides a renewed window of opportunity for a Great Transformation towards more sustainable futures. It reviews Transition Towns, Beyond GDP and Common Good Economies as examples of movements that lead the way in putting a new paradigm into practice.
Reforming the EU VAT system to support the transition to a low-carbon and resource efficient economy
(2015)
This chapter discusses the question of ecologically differentiated value added taxes (VAT) as a tool to overcome tax-related cognitive barriers by connecting to an existing tax system. This is elaborated along several aspects: (a) The role indirect of consumption taxes for the economy, (b) the legal issues of the VAT system, (c) the EU harmonization efforts in this context, (d) the distributional implications of value added taxes. Following this, the chapter develops a proposal for a VAT reform (e). To this end, it looks at potential and existing differentiations between sectors, products and services, and product and service groups and turns to those consumption areas that are widely identified as particularly resource and carbon intensive and sets out how a harmonization of the overall system and an ecological differentiation in single consumption areas could be brought together. Potential impacts and effects are briefly discussed (f) and some conclusions are drawn (g). The subject addressed in the chapter is relevant from a policy perspective but mainly descriptive: It does not use innovative qualitative and quantitative tools.
The Ernst Strüngmann Forum seeks to link justice, sustainability, and diversity agendas. In support, this chapter discusses how linkages between these three concepts have formed and changed in the climate change discourse, particularly in light of the recent Paris Agreement. As the latest addition to the portfolio of international climate change agreements, the Paris Agreement establishes a landscape in which nation-states, subnational actors, and transnational networks will be able to reconfigure existing linkages between sustainability, diversity, and justice, and perhaps improve upon them.
Here, three possible developments are identified which may substantially influence the reconfiguration process. Recognition is given to the sustainability and justice deficits that have plagued the "top-down" character of the international climate change discourse, and it is hypothesized that the Paris Agreement opens the door for "bottom-up" movements to claim a larger segment of climate change policy decision making and design. In turn, the "polycentric" landscape created by such "movement from below" appears to emphasize concepts such as inclusivity and transparency perhaps allowing for explicit climate justice commitments. Finally, to advance societal transformation and embrace diversity, it is hypothesized that the scientific endeavor needs to be transformed from a purely analytical pursuit to an effort that makes use of the wide range of scientific competences and provides support for transformative innovations to change unsustainable sociotechnical systems.
The energy sector today accounts for about 10% to 15% of global freshwater withdrawal. Most water in the energy sector is used for generating electricity, especially for cooling processes in thermal power plants. At the same time the demand for electricity is expected to increase significantly due to population growth and economic development in emerging and developing economies. Growing demand is also driven by electrification strategies pursued by industrialized countries to decarbonize their economies. With the global demand for electricity expected to increase significantly in the coming decades also the water demand in the power sector is expected to rise. However, due to the on-going global energy transition, the future structure of the power supply - and hence future water demand for power generation - is subject to high levels of uncertainty because the volume of water required for electricity generation varies significantly depending on both the generation technology and cooling system. In light of these challenges the objective of this analysis is to provide more systematic and robust answers in terms of the impacts of different decarbonization strategies in the electricity sector on water demand at global and regional level. The focus is on operational water use for electricity generation.
This chapter turns to the measurement of performance in delivering corporate and ecosystem purposes. The metrics are designed to capture the pain points in the ecosystem that need to be addressed and the success of the intervention in addressing them. This requires measures of non-financial as well as financial performance. The chapter provides an overview of measurements of non-financial forms of capital: natural, human, and social. In examining natural capital, it contrasts input measures that record the amount of natural resources that are used in the production process and output measures that examine the impact of the inputs on products, emissions, waste, etc. It notes that measuring inputs is in general more straightforward than outputs and it therefore argues that natural capital metrics should be constructed around inputs rather than outputs.
This chapter reconstructs the main actors, objectives and the pertinent contextual factors that co-determined the German coal phase-out. The German decision to phase out coal no later than 2038 was prepared by intense negotiations under the German "coal commission". It was tasked with finding an end date for coal-fired electricity generation and proposing ways and means to support coal workers and the affected regions. This latter objective was the dominant one, supported by a coalition of trade unions, industry, state-level governments as well as major political parties fearing a surge of far-right populism. Meanwhile, meeting the German climate targets was a key condition in the mandate of the coal commission. Yet, the German targets date back to 2010 and are not aligned with the more ambitious objectives enshrined in the Paris Agreement. This explains why the German coal phase-out schedule is so late and so expensive.
