Options and potentials for energy end-use efficiency and energy services : summary ; final report
(2006)
Combining environmental with employment objectives, ecological tax reform (ETR) envisages a double dividend. While research has mainly focused on the socio-economic and environmental impacts of ETR, there is less literature on the social responses. This paper gives an overview and history of German ETR as well as investigating the understanding of perceptions and attitudes towards ETR of those being "subject to tax". The research is based on qualitative social research methods. As with the other PETRAS papers, interviews were conducted with policy-makers and business leaders and focus groups were formed with lay persons. The results show that responses of policy-makers and business leaders are modest. Although some criticisms about the specific design of the German ETR remain, complaints towards ETR are settled. Attitudes appear influenced by more fundamental convictions such as economic interest or altruistic views. In contrast, ETR appears to politicise common people. Attitudes are influenced by the overall comprehension of the ETR concept, the expected impacts, perceived information deficits, as well as a general distrust in politics. Our data show that the linking of environmental and employment objectives is not understood and not welcomed. In order to increase social acceptance, the paper discusses refocusing ETR on environmental objectives, modestly increasing the share of ETR revenue spent for environmental purposes, removing inconsistencies in the ETR design, and improving information policy.
This article presents the findings of a European study on energy efficiency in the public sector, entitled "Public procurement of Energy Saving Technologies in Europe" (PROST), completed in 2003. Energy efficiency in the public sector goes far beyond energy savings and climate protection. Energy efficiency must be seen as a strategy, which deals both with scarce public funds and with profound energy and climate challenges. The gains to be made are substantial. The study assessed the potential for energy and cost savings and the greenhouse gas reductions that are linked to energy efficiency in the European public sector. To the knowledge of the authors, this is the first time such an analysis has been carried out. The study concluded that there are no fundamental legal obstacles that would a priori disable the public sector from procuring energy efficient technologies or applying energy efficiency considerations in its daily building management routines. However, at the level of implementation obstacles can occur. It is therefore of paramount importance that there is sufficient political will and adequate incentive systems at all relevant levels. It appeared to be particularly effective when public procurement is energy-efficiency minded in all its operations and life cycle costing is applied for investments instead of conventional public budgeting procedures. The study demonstrates that consistent and EU-wide application of these principles and instruments can result in rather substantial savings both in terms of energy and in terms of money. With additional annual investments in energy efficiency of 80 million Euro, energy savings in the (EU15) Member States' public sector worth up to 12 billion Euro per year can be achieved. A supplementary analysis was performed for a selection of the new Member States, which indicated that the potential for energy and fiscal savings is substantial in those countries as well.
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 concept of corporate resource efficiency accounting : a case study in the electronic industry
(2006)
Holiday travel behavior, individual characteristics of holiday travelers and strategies to change holiday travel behavior are the subjects of this article. From the environmental perspective, the journey to the destinations is the most critical aspect of traveling. Based on a 2003 survey of 1991 German inhabitants, the kilometers traveled and the choice of transportation mode for holiday purposes have been quantified. According to the number of trips and kilometers traveled, four travel groups have been identified. The groups vary according to socio-demographics, psychological factors, number of holiday trips, and travel mode choice. Persons who traveled to more distant destinations also traveled more often and used air travel for more than 60% of their trips. For the other groups, car travel was more important. Correlating the four travel groups with greenhouse gas emissions reveals that the smallest group - the long-haul travelers - was responsible for 80% of the emissions of the whole sample. Income, education, and openness to change were main indicators of individual greenhouse gas emissions. Target group oriented strategies to reduce the environmental impact of holiday mobility are discussed against the background of 84 in-depth interviews conducted with selected representatives of the first survey.
This paper introduces the special issue on the Policies for Ecological Tax Reform: Assessment of Social Responses (PETRAS) project about responses to ecological tax reform (ETR) in Europe. Although ETR is widely accepted to be a policy with desirable effects, its implementation has been limited by problems of political acceptability. The project aimed to address the question of how to make such a policy more acceptable. It is the first study to examine in depth the thinking of members of the general public about the ETR policies and is also the first international comparative study of the thinking of ordinary business people about ETR policies. The PETRAS project methodology was based around the use of interviews and focus groups to inform the assessment of social responses to ETR policies and the development of improved designs for them. A number of issues emerged relating to awareness, trust, understanding of the purpose, visibility, incentives, regressivity, levels of taxation, terminology, communication about ETR and the use of alternative instruments. Together with these similarities, a pattern of differences between the countries can also be seen. The final section of this paper introduces the national studies described in the following papers.
Accounting for the social dimension of sustainability : experiences from the biotechnology industry
(2006)
Accounting for the social dimension of sustainability proves to be a challenge for corporate practitioners, due to its intangible, qualitative nature and lack of consensus on relevant criteria. We suggest a semi-quantitative approach based on stakeholder involvement to identify relevant aspects for a sector specific assessment of the social dimension. Our case study on biotechnology illustrates that the dialogue with internal and external stakeholders enabled the creation of a key performance indicator (KPI) set to account for social sustainability in the early design stages of biotechnological processes and product development. Indicators for eight aspects are identified for the social assessment: health and safety, quality of working conditions, impact on employment, education and training, knowledge management, innovation potential, customer acceptance and societal product benefit, and social dialogue. We describe the integration of the KPI set in a software application, tailor made for practitioners of the sector, and highlight first user experiences.
Assessing social aspects
(2006)
In this paper Justus von Geibler, Kora Kristof and Jan Walter highlight how sustainability demands can be integrated in early innovation phases and how new markets for sustainable products can be explored. The paper describes related experiences from a research project on future market development for timber in the building sector, conducted for the German Ministry for Research and Education.
The role of hydrogen in long run sustainable energy scenarios for the world and for the case of Germany is analysed, based on key criteria for sustainable energy systems. The possible range of hydrogen within long-term energy scenarios is broad and uncertain depending on assumptions on used primary energy, technology mix, rate of energy efficiency increase and costs degression ("learning effects"). In any case, sustainable energy strategies must give energy efficiency highest priority combined with an accelerated market introduction of renewables ("integrated strategy"). Under these conditions hydrogen will play a major role not before 2030 using natural gas as a bridge to renewable hydrogen. Against the background of an ambitious CO2-reduction goal which is under discussion in Germany the potentials for efficiency increase, the necessary structural change of the power plant system (corresponding to the decision to phase out nuclear energy, the transformation of the transportation sector and the market implementation order of renewable energies ("following efficiency guidelines first for electricity generation purposes, than for heat generation and than for the transportation sector")) are analysed based on latest sustainable energy scenarios.
Because of high efficiency, low environmental impacts and a potential role in transforming our energy system into a hydrogen economy, fuel cells are often considered as a key technology for a sustainable energy supply. However, the future framing conditions under which stationary fuel cells have to prove their technical and economic competitiveness are most likely characterised by a reduced demand for space heating, and a growing contribution of renewable energy sources to heat and electricity supply, which both directly limit the potential for combined heat and power generation, and thus also for fuelcells. Taking Germany as a case study, this paper explores the market potential of stationaryfuelcells under the structural changes of the energy demand and supply system required to achieve asustainable energy supply. Results indicate that among the scenarios analysed it is in particular a strategy oriented towards ambitious CO2-reduction targets, which due to its changes in the supply structure is in a position to mobilise a market potential that might be large enough for a successful fuel cell commercialisation. However, under the conditions of a business-as-usual trajectory the sales targets of fuel cell manufacturers cannot be met.
Many concepts are able to initiate an increase in resource productivity in enterprises and supply chains – although some of these approaches do not directly address resource efficiency. From these instruments, we derived seven important set-screws, pointing at the most important starting points for resource productivity. Considering the differences of the examined set-screws in general and of the approaches lying in the background in particular, the existing portfolio of instruments seems broad enough to successfully implement instruments aiming at an increase of resource efficiency in the enterprises. However, it is necessary to adapt the selection of instruments to the conditions of the specific enterprise.
COMPASS to sustainability
(2006)
Information and communiction technologies (ICTs), as a crosscutting evolving technology, can contribute to the achievement of the Millennium Development Goals (MDGs). This opinion is not only voiced by business, but also expressed in specific MDG targets as well as from a range of stakeholders, e.g. NGOs, intergovernmental organisations and financial institutions. However, ICT implications are not only beneficial, a range of stakeholders raises critical issues. Quantified information on ICT contribution to the MDGs available today on both micro and macro level does not meet the expectations. Business actors thus need solid and balanced sustainability information to accurately get the implications of ICT and to promote and assess their voluntary activities. In this context the project "A Comprehensive Approach for Assessing Risks and Opportunities of the ICT sector and ICT applications" addressed the contributions of the ICT sector to the achievement of the MDGs. The project's core objective has been to develop a discussion paper on the assessment of risks and opportunities of ICT. The scope of the paper is to raise awareness for a balanced approach of sustainability information (regarding the contribution to the MDGs, at micro and macro level, risks and opportunities) and to provide best practice examples for a comprehensive approach in the ICT sector. Therefore, research questions have been addressed such as: How can ICT contributions to the MDGs be quantified? What are the demands on sustainability information for the ICT sector? What are the business implications from this?
After considerable improvements of wastewater treatment, the loads of nutrients and plant protection agents, deriving from agriculture and heavy metals from urban drainages effluents as well as from erosion of agricultural soils are the main sources of nutrients and harmful substances in the loads of water bodies. The targets of the project were on the one hand the analysis of the political and legislative framework of both policy fields and on the other hand the evaluation of several, selected water protection measures with regard to their contribution to reduce water pollution, their economical effects as well as their political enforceability. The focus was laid on diffuse water pollution caused by agriculture. As main reasons for the diffuse water pollution stagnating at high level, the analysis of the political framework identified a lack of implementation discipline of water law, followed by the fragmented and insufficient water protection legislation itself and the previous design of the common agricultural policy slanted towards increasing productivity. For the future co-operation of agricultural and water authorities in implementation of their reforms and better definition of "Good Farming Practice" are recommended. The second investigation level focuses on the analysis and assessment of selected measures to reduce the input of nutrients and plant protection agents. This part was done with help of calculation models focussing on the specific cost/benefit ratios for water protection. In detail the following measures have been analysed: decoupling of direct payments, coupling of livestock farming to areas, tax on mineral nitrogen, pesticide levy, buffer stripes alongside of watercourses, all season crop cover on arable land, soil cultivation procedures, changing the use of arable land, optimisation of animal nutrition, optimisation of manure storage and application, co-operative agreements, education and training. Co-operations and water protection related education and training can be highly recommended, since they improve knowledge and freedom of action. As the results on county level show, the measure "Decoupling of direct payments" would not lead to appreciable changes as far as the nutrient surpluses on farmland is concerned. "Coupling livestock farming to areas" would decrease the surpluses substantially. For this measure and Tax on mineral nitrogen, varying adaptation reactions could be expected depending on the regional specialisation in cropping or livestock farming areas. On single farm level the measures, protein adapted feeding, optimisation of manure storage and application showed the best cost-efficiency to reduce nutrient surpluses. All season crop cover on arable land and conservation tillage are highly efficient, too, and should be included in farming practice. A stronger limitation of livestock density could mean a reduction of manure, but the implementation of this measure would lead to high losses of income for farmers specialised in animal production. For reduction of diffuse water pollution caused by urban drainage political approaches as well as detailed technical measures are examined. In the area of urban drainage storm water management (especially infiltration and constructed wetlands), unsealing of paved areas and small wastewater treatment structures (for phosphorus reduction) showed best cost-effectiveness.
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.
Global climate
(2006)
Considering the enormous ecological and economic importance of the transport sector the introduction of alternative fuels - together with drastic energy efficiency gains - will be a key to sustainable mobility, nationally as well as globally. However, the future role of alternative fuels cannot be examined from the isolated perspective of the transport sector. Interactions with the energysystem as a whole have to be taken into account. This holds both for the issue of availability of energy sources as well as for allocation effects, resulting from the shift of renewable energy from the stationary sector to mobile applications. With emphasis on hydrogen as a transport fuel for private passenger cars, this paper discusses the energy systems impacts of various scenarios introducing hydrogen fueled vehicles in Germany. It identifies clear restrictions to an enhanced growth of clean hydrogen production from renewable energy sources (RES). Furthermore, it points at systems interdependencies that call for a priority use of RES electricity in stationary applications. Whereas hydrogen can play an increasing role in transport after 2030 the most important challenge is to exploit short–mid-term potentials of boosting car efficiency.
At the time of the Rio Conference, it had already become clear that climate change is far from being just an ecological issue; it is also an issue of equity. In particular, climate change was identified as an issue of intergenerational equity. It became ominously clear to observers that global warming, since it modifies important parameters of the ecology of the planet, such as sea levels or weather patterns, will affect the relations between present and future generations. Today's generation, by filling up the absorptive capacity of the atmosphere, lives at the expense of tomorrow's generation. At the same time, it came to the fore that the use of fossil fuels not only affects inter-generational equity, but also intra-generational equity, i.e., the relations between nations and social groups within a generation. Who will be allowed to reap the benefits from fossil fuel combustion? Who will have to carry the burden of emission abatement? Equity within a generation has at least two dimensions (Wuppertal Institute, 2005). First, it implies the fair distribution of burdens and benefits of fossil fuel use among nations. Secondly, however, it also implies the universal protection of human dignity by securing the fundamental rights of every human person to water, food, housing, and health. The article will focus on the latter dimension; it will explore the links between human rights and climate change, without, however, losing sight of the broader framework of equity in climate politics.
