Transformative Innovationen : die Suche nach den wichtigsten Hebeln der Großen Transformation
(2021)
Der hier vorliegende Zukunftsimpuls soll den Grundgedanken der Transformativen Innovationen und ihre Notwendigkeit beschreiben sowie erste Kandidaten für solche Transformativen Innovationen aus diversen Arbeitsbereichen des Wuppertal Instituts vorstellen. Er dient vor allem als Einladung, gemeinsam mit dem Wuppertal Institut über solche Innovationen zu diskutieren, die irgendwo zwischen den großen Utopien und kleinen Nischenaktivitäten liegen. Denn es braucht nicht immer den ganz großen Wurf, um Veränderungen in Gang zu setzen.
The Digital Product Passport (DPP) is a concept of a policy instrument particularly pushed by policy circles to contribute to a circular economy. The preliminary design of the DPP is supposed to have product-related information compiled mainly by manufactures and, thus, to provide the basis for more circular products. Given the lack of scientific debate on the DPP, this study seeks to work out design options of the DPP and how these options might benefit stakeholders in a product's value chain. In so doing, we introduce the concept of the DPP and, then, describe the existing regime of regulated and voluntary product information tools focusing on the role of stakeholders. These initial results are reflected in an actor-centered analysis on potential advantages gained through the DPP. Data is generated through desk research and a stakeholder workshop. In particular, by having explored the role the DPP for different actors, we find substantial demand for further research on a variety of issues, for instance, on how to reduce red tape and increase incentives for manufacturers to deliver certain information and on how or through what data collection tool (e.g., database) relevant data can be compiled and how such data is provided to which stakeholder group. We call upon other researchers to close the research gaps explored in this paper also to provide better policy direction on the DPP.
The South African government started the development of a basic energy efficiency policy framework in 2005, including a voluntary label for refrigerators. This initial label was the intended precursor to a mandatory standards and labelling (S&L) programme, but the impacts achieved were only very limited. Based on this first experience, the South African Bureau of Standards (SABS) formed in 2008 a working group for the development of the new and more specific South African National Standard SANS 941. This standard identifies energy efficiency requirements, labelling and measurement methods as well as the maximum allowable standby power for a set of appliances as reliable basis for introducing a mandatory regulation. Nevertheless, due to many existing barriers, such as lack of funding and low priority assigned to the initiative, a very long period passed by between the S&L planning and final policy implementation. Finally, in November 2014, the South African government published mandatory performance standards coming into force in 2015/2016 for a first set of appliances consisting of refrigerators, washing machines, dryers, dishwashers, electric water heaters, ovens, A/C and heat pumps. To analyse the effectiveness of the new S&L programme and the potential influence of delays in the implementing process, the authors performed an immediate first-hand evaluation of the new policy.
As analytical reference base for available energy efficiency potentials, results from bottom-up scenario calculations will be presented exemplarily as case study for cold appliances covered by the S&L programme. A retrospective market study will show market trends before policy implementation and compare results with the new mandatory requirements. For the further policy analysis, a programme theory approach will be applied, in order to better understand why, how and under what conditions the policy works. Relationships with other energy efficiency policies and measures as well as positive or negative effects will be described. Furthermore, cause-impact relationships will be analysed to explain the functioning of the policy. Finally, success and failure factors will illustrate what needs to be done to achieve the desired energy efficiency targets. Henceforth, even though this study does not assess the direct transferability of the South African S&L programme to other regions, its findings could be relevant and useful for countries planning the implementation of similar policies.
Washing laundry is one of the most widespread housework tasks in the world. Washing machines, performing this task already in many private households, are now responsible for about 2% of the global electricity consumption. Worldwide, more than 840 million domestic washing machines are in use, with an annual consumption exceeding 92 TWh of electricity and 19 billion m3 of water as well as causing emissions of more than 62 megatons CO2eq. In North America, Western Europe and Pacific OECD countries, most households own a washing machine. In these economies standard and label policy programs already addressed and reduced the specific electricity and water consumption of washing machines per wash cycle. Nevertheless, in other world regions, the level of ownership for washing machines is still well below saturation and high growth rates can be observed in developing and newly industrialising countries. As washing machines use water, electricity, chemical substances and process time as resources, also the absolute worldwide resource consumption and emissions of these appliances are still on the rise. Due to different washing habits and practices as well as types of washing machines in different world regions, the specific consumption of resources for doing the laundry is varying to a large extent. On that score, this paper presents an overview of the current situation worldwide as well as respective saving potentials. Bottom-up scenario calculations, carried out for the 11 world regions according to the Intergovernmental Panel on Climate Change classification, show that large energy, water and greenhouse gas savings are possible with the "Best Available Technologies" today, and even higher savings will be possible with next generation "Best Not yet Available Technologies". According to model results, these savings are usually also very cost-effective. Following these calculations, it is highly advisable for policymakers world-wide to pay even more attention to improvement options in order to implement ambitious and product-specific policy packages, including minimum performance standards and labelling schemes.
Small-scale residential biomass combustion for space heating and warm water production already holds a considerable share on overall energy production from biomass in Europe. In the existing regulative framework of EU air quality and climate protection targets, an extended usage of renewable biomass heating without an increase of harmful emissions is urgently needed. In this context, the FP7 project "EU-UltraLowDust" (ULD) aimed at the demonstration of highly efficient and ultra-low emission small-scale biomass combustion technologies and the development of supporting policy recommendations.
New combustion technology operating at almost zero particulate matter (PM) emissions has been demonstrated, rivalling even the performance of state-of-the-art natural gas fuelled systems. In this context, the authors analysed EU policy options for a faster diffusion of these new innovative technologies. The analysis presented in this paper is based on results from an original impact assessment with special focus on energy efficiency and emission scenarios, including the potential effects of a broad deployment of the new ULD technologies as well as the early replacement of poor performing existing installations.
As the derived results show that major shares of energy consumption and emissions from residential biomass combustion in the EU are caused by old heating systems, specific policy measures for new and existing installations have been analysed. Following this, a recommended and harmonized policy package for new Small Combustion Installations (SCI) to be put on the market as well as for existing SCI in the stock has been developed, which will be presented in this paper. The basic policy package addresses new installations and consists of a two-step approach, aiming at enhancing the current and forthcoming policies addressing the SCI market in Europe. A complementary second policy package for existing installations aims specifically at the early replacement of SCI already installed in the stock, which are characterized by low efficiency and high emissions.
The widely recognised Energiewende, ("energy transition") in Germany has lost its original momentum. We therefore address the question of how the transition process to a new energy system can be reignited. To do so, we developed the "5Ds approach", which lays the groundwork for a process analysis and the identification of important catalysts and barriers. Focusing on the five major fields required for the energy transition, we analyse the effects of: (1) Decarbonisation: How can efficiency and renewable energies be expanded successfully? (2) Digitalisation: Which digital solutions facilitate this conversion and would be suitable as sustainable business models? (3) Decentralisation: How can potential decentralised energy and efficiency opportunities be developed? (4) Democratisation: How can participation be strengthened in order to foster acceptance (and prevent "yellow vest" protests, etc.)? (5) Diversification of service: Which services can make significant contributions in the context of flexible power generation, demand-side management, storage and grids? Our paper comes to the conclusion that German policy efforts in the "5D" fields have been implemented very differently. Particularly with regard to democratisation, the opportunities for genuine participation among the different social actors must be further strengthened to get the Energiewende back on track. New market models are needed to meet the challenges of the energy transition and to increase the performance of "5D" through economic incentives.
