Description: This paper draws upon an extensive transdisciplinary scenario development in the context of the stakeholder oriented preparation of the climate protection plan of the German federal state North Rhine-Westphalia, which is home to the most important heavy industry cluster in Europe. In that context we developed differentiated bottom up climate change mitigation strategies and scenarios for the major energy intensive industries aluminium, iron and steel, cement, lime, paper and steam cracker for olefin production together with representatives of industry as well as society.

Description: Climate change and thus low-carbon transitions are global challenges, which require commitment and effort on all political levels. As international climate politics has approached its limits over the last two decades, the role of cities has simultaneously gained in importance. Many cities1 worldwide have committed to ambitious climate protection targets, which often exceed national targets. However, cities cannot act in isolation. Their opportunities for action are embedded in an (inter)national policy framework, which may either support or hinder local actions. This gives rise to the question: which opportunities for climate protection do cities really have in a political system of multi-level governance? This question can be illustrated using the city of Hamburg as an example for the German climate policy regime. The city aims to reduce its annual CO2 emissions by 2 million metric tons and attempts to quantify the impact of local and national policies and actions using a bottom-up monitoring approach. We therefore analyse more than 400 local actions with respect to the induced CO2 emission reductions. We also take a closer look at national and European policies and their impacts on local energy use and emissions. In total, 15 policies and instruments - broadly ranging from instruments to foster energy efficiencyin residential and non-residential buildings, in appliances and in the transport sector, to support renewable energy sources (including biofuels) and to uptake CHP - are considered. Our approach consists in measuring separately the impact of local and national policies and actions on urban CO2 emissions. While the city of Hamburg has implemented many policies and actions, our results show that, a significant proportion of its CO2 reduction is due to national policies, in the context of the German "Energiewende", which cannot or can only indirectly be influenced by the city. The results imply that local commitment and effort is essential in addressing the global challenge, yet ambitious targets can only be met in the presence of a supportive national policy framework. The analysis shows that many policies and measures implemented at national level require supportive structures and activities at local level in order to bridge information and implementation gaps of these measures.

Description: Many European city governments have voluntarily committed to ambitious CO2-emission reduction targets until 2020 and 2050. Supported by dedicated structures and networks (e.g. Covenant of Mayors), local governments have already developed, or are currently developing, ambitious climate action plans, all pursuing the aim of radical CO2-emission reduction in the long term. Though, the development of climate action plans is only a first step, as the actual crucial and more challenging part its implementation. Besides financial investments also additional capacities, improved institutional structures and innovative strategies are necessary to successfully implement ambitious policies within existing national and regional framework conditions. There is often more competition than co-operation between cities. However, exchanging on common challenges in order to find new solutions provides potential for innovative ideas and new views on own structures. In particular, methods and formats for self-assessment and mutual learning can support cities' stakeholders to overcome their implementation gap in local energy and climate policies. This paper will present results from the first phase of the three year project "CASCADE", which was initiated by 19 European cities in co-operation with EUROCITIES. Within the project, implementation challenges are being addressed in an intensive process of self-assessment and mutual learning. The methodological "backbone" of this process is a qualitative benchmarking framework in the thematic fields of "Renewable energy sources and distributed energy generation", "Energy efficient buildings and districts" and “Energy in urban transport”. Up to a certain degree, existing local climate policy benchmarks provide a common exchange platform, but mainly for the comparison between cities. The CASCADE benchmarking framework goes beyond competitive comparisons. As a qualitative criteria-based assessment procedure it identifies key challenges and factors for a successful implementation of established local climate policy plans. These factors have been developed from a qualitative survey including interviews and workshops with representatives of the participating cities. Six cities serve as examples. Self-assessment reports were provided based on the CASCADE benchmarking framework focussing on the implementation status of their local climate policies. These reports were reevaluated by four or five project partners from different cities in a desk-review process. During subsequent four-days peer learning visits, the CASCADE benchmarking framework was used again as a tool for an in-depth assessment of the local climate and energy action plans and the local activities towards implementation of these strategic documents. Finally, the visitors drafted a feedback report with recommendations and improvements for the hosts. The paper describes the methodology of the CASCADE benchmarking framework for integrated learning, its applicability for peer learning processes, as well as first experiences and results from the peer learning visits.

Description: The project "bigEE - Bridging the Information Gap on Energy Efficiency in Buildings" presents comprehensive information for energy efficiency in buildings and the related policy on the international internet-based knowledge platform bigee.net. To develop the evidence-based information required for bigee.net, we addressed in a different and more systematic way than usual the question of how policy can support improved building energy efficiency most effectively: We combined (1) a theoretical, actor-centred analysis of market-inherent barriers and incentives for all actors in the supply and use chain of (energy-efficient) buildings to derive a recommended package combining the types of policies and measures the actors need to overcome all these barriers, with (2) empirical evidence on model examples of good practice policy packages to check if advanced countries have indeed used the combination of policies we derived from the actor-centred analysis. In this way, we found that the recommendable policy package for new buildings is similar to the well-known one for appliances, but with the objective to mainstream nearly zero energy buildings. By contrast, the task for existing buildings is two-dimensional - increasing the depth of renovation first, to savings of 50 to 80%, and then the rate of energy-efficient renovation to 2% or more p.a. - and so the policy package needs more emphasis on individual advice, incentives, and financing. The paper presents the recommended packages as well as a comparison of existing national policy packages from California (USA), China, Denmark, Germany, and Tunisia and what we learned from it for effective packages and implementation.

Description: The role of cities in mitigating GHG emissions and thus tackling global warming has gained importance over the last years.Many cities have developed climate action plans, primarily to achieve long-term "low-carbon" mitigation goals set by national governments or (inter)national agreements. A mere adoption of high level targets, however, raises the question whether these targets are applicable for cities with very different framework conditions. We argue that it is crucial to understand the socio-economic, geophysical, spatial, infrastructural and political framework of a city - a broad approach, which is generally missing in climate action plans. Thus, determining drivers and barriers for future development paths is neglected by local policies, which leads to a gap between ambition (target) and reality (implementation). We exemplarily examine this hypothesis for the shrinking city of Oberhausen (Germany). Oberhausen, located in the Ruhr area,is a typical old industrial region, which has seen a decline of its industrial basis over the last decades. We analysed historical data and developed scenarios until 2030. Both show a significant decrease in CO2 emissions. A closer look, however, reveals that the reduction is primarily due to the economic transformation (less manufacturing, more service industry, accompanied by a decrease in population) and general energy efficiency developments following the implementation of national and EU policies. Although the city has implemented–and will further implement - many instruments and policies to reduce CO2 emissions, local barriers such as unemployment, low rents, low income, high per capita debts, etc. dramatically reduce the city's capacity for action. The results show that Oberhausen's emission reductions do not reflect active energy policies but are mainly driven by an economic decline. To reach ambitious reduction targets, however, the city needs to be enabled to take action in achieving appropriate and reasonable targets.

Description: Conventional new buildings in OECD countries with a history of building codes save about 50 % of energy compared to average buildings in the building stock. This improvement, however, is not enough to create a building standard with low lifetime costs nor to reach long-term climate protection targets. Much higher energy savings can already be achieved through proven high-efficiency building concepts bringing net economic benefits among other advantages. A strategic approach to integrated building design is the key to achieving these high-energy savings at low or no extra cost in residential buildings. In our paper we describe the "Easy Efficiency Approach", which can reduce primary energy consumption by 40 to 60 % compared to conventional new building standards, or by 70% to 80% when compared to the primary energy consumption of the existing building stock, and should be regarded as the minimum. This strategy focuses on low-cost options, mainly passive options. Although it can already significantly reduce energy consumption, this first step will not be sufficient to reach long-term climate protection goals. It is thus necessary to implement and support what we call an "Advanced Efficiency Approach", with savings up to 90% , as compared to new building standards, as soon as possible to avoid lock-in effects. Further improvements, especially through the active use of renewable energies, reduce the net primary energy demand to 0 % and beyond. According to the chosen strategy clearly defined energy performance ranges, with reference to possible savings, for different climate zones worldwide are given. In verifying this approach simulations with BAT (Best Available Technologies) buildings of different types (single family, multi family, high rise) were carried out in close cooperation with project partners. This data has also been verified through an empirical database of built examples both for energy consumption as well their economic soundness.

Description: Several low-carbon energy roadmaps and scenarios have recently been published by the European Commission and the International Energy Agency (IEA) as well as by various stakeholders such as Eurelectric, ECF and Greenpeace. Discussions of these studies mainly focus on technology options available on the electricity supply side and mostly omit the significant challenges that all of the scenarios impose on the energy demand side. A comparison of 5 decarbonisation scenarios from 4 of the most relevant recent scenario studies for the EU shows that all of them imply significant efficiency improvements in traditional appliances, usually well above levels historically observed over longer periods of time. At the same time they assume substantial electrification of transportation and heating. The scenarios suggest that both of these challenges need to be tackled successfully for decarbonising the energy system. With shares of renewable electricity reaching at least 60 % of supply in 2050 in almost all of the decarbonisation scenarios, the adaptation of demand to variable supply becomes increasingly important. This aspect of demand side management should therefore be part of any policy mix aiming for a low-carbon power system. Based on a quantitative analysis of 5 decarbonisation scenarios and a comparison with historical evidence we derive the (implicit) new challenges posed by the current low-carbon roadmaps and develop recommendations for energy policy on the electricity demand side.

Description: Which factors are crucial to successfully design and implement a "good practice" policy to increase the energy efficiency of buildings and appliances? This is one of the main challenges for the new web platform bigee.net that provides guidance on good practice policies. In this paper we examine the question what "good practice" is by presenting a multi-criteria assessment scheme to analyse different policies worldwide. The assessment scheme contains a set of criteria addressing key factors leading to the success of a policy as well as its outcomes: a good policy addresses all market players and barriers, avoids lost opportunities and lock-in effects, has ambitious and regularly updated energy efficiency levels, and spill-over effects. Other criteria are high energy savings and the calculated cost-effectiveness. The assessment scheme provides a standardised data collection approach, which paves the way for both qualitative and quantitative evaluation. Furthermore, it can help policy-makers to transfer a successful policy. The development of the scheme is based on a literature review of worldwide implemented policies and measures that promote energy-efficiency of buildings and appliances. Criteria were operationalized, including a ranking between 0 and 10. The ranking is a decisive factor whether the policy qualifies as good practice. To demonstrate the practicability of this scheme, the paper analyses a good practice example according to the assessment scheme: Energy-Efficient Refurbishment and Energy Efficient Construction programmes of the German public bank KfW.

Description: Refrigerators and freezers (subsumed under the term "cold appliances") are among the most widely used electrical appliances in the residential sector all around the world. Currently, about 1.4 billion domestic cold appliances worldwide use about 650 TWh electricity, which is 1.2 times Germany’s total electricity consumption, and cause CO2 emissions of 450 million tons of CO2eq. Although the specific electricity consumption per volume of cold appliances has decreased during recent years due to technical progress and policy instruments like labelling and eco-design requirements, total worldwide energy consumption of these appliances is on the increase. Scenario calculations were carried out for 10 world regions by the Wuppertal Institute. Results show that about half of the energy consumption could be saved with the most energy-efficient appliances available today, and even higher savings will be possible with next generation technologies by 2030. According to the analysis, these savings are usually very cost-effective. All these aspects are part of the new website "bigEE.net - Your guide to energy efficiency in buildings" which aims to provide information about technical options but also about policies to support the development of energy-efficient appliances. To initiate and foster market transformation of energy-efficient appliances it is highly advisable for policymakers to generate appliances-specific policy packages. Since each regional market has its specificity (e.g. energy prices, typical appliance affecting the cost effectiveness of efficient appliances), the barriers for the market transformation of single product groups are also specific and need to be addressed by appropriate policies and measures. Elements of measures to build appropriate specific policy packages for refrigerators will be presented in the paper, and the refrigerator package from California (USA) demonstrates the successful implementation of a sector-specific package.

Description: The cement industry is one of the major energy consuming and CO2 emitting sectors in China. In 2010, 1,868 million tons of cement has been produced, which accounted for 56.1% of the world's total cement production. The 11th Five-Year Plan (FYP) (2006-2010) included policy measures for CO2 emission abatement in cement production. Based on the main governmental framework of CO2 mitigation policies at national level in the cement sector, key policies and technologies used during this period are identified and their effects on CO2 reduction are assessed. This paper calculates the reduction of CO2 emissions related to four main policies and technologies for efficient cement production in the 11th and the 12th FYP (2011-2015) with 2005 as a reference year. These are waste heat recovery, closing outdated facilities, substitution for clinker production and other technologies aiming to increase energy efficiency. Due to these measures, we estimate that a total CO2 emission reduction during the 11th FYP of 397 million tonnes could be saved, which is considerably different to 185.75 million tonnes estimated by Zeng (2008) and 303 million tonnes by the NDRC by using different calculation methods. Of the four technologies, the 4th group of energy efficiency increasing techniques was the most important policy and avoided the largest amount of CO2 emissions. Previous energy intensity reduction was mainly due to the outdated production closing and energy efficiency improving. Based on the assessment of technology performance, it appears that there is still a large emission reduction potential in cement production processes. The paper calculates this potential for the 12th FYP period (2011-2015) based on these four identified policy measures. The result is compared to the Chinese government targets in the 12th FYP and promising future CO2 mitigation policies and technologies are proposed, such as the use of alternative energy.

Description: What are the best policies and measures to stimulate energy efficiency in buildings? The debate around this is at least as diverse as the markets and concepts for energy efficiency in buildings, and often quite controversial. However, no magic formula seems to have been found so far. It is, therefore, time to address the question in a new way - by combining both theoretical evidence on what policy support markets need, and empirical evidence on which combinations or packages of policies have worked. In the context of its new four-year project bigEE - "Bridging the Information Gap on Energy Efficiency in Buildings", the Wuppertal Institute is implementing this new approach. The bigEE project aims at developing an international internet-based knowledge platform for energy efficiency in buildings. Hence, it must provide evidence-based information. On the theoretical side, the analysis starts with value chains in the building sector and the barriers but also actor-inherent incentives that the different types of market participants face. This enables to identify, which policies and measures need to be combined to jointly overcome the barriers and strengthen the incentives. On the empirical side, model examples of good practice are collected and compared. The search for these is guided by the results of the theoretical analysis, international expert opinion, and existing databases and platforms. In order to identify what is "good practice", the project uses a newly developed multi-criteria assessment scheme. Finally, the impacts achieved with the model examples, lessons learned, and their transferability will be used to validate the model policy package identified in the theoretical analysis. The public launch of the bigEE platform is planned for autumn of 2011; eceee Summer Study participants will get a first glance at its content through this paper. The paper presents the methods and tools used and showcases their application for the case of new buildings

Description: The general conditions for local authorities in Germany have changed fundamentally during the last decades. Not only do municipalities compete with each other for employment, prestige and competitive advantages, they also face increasingly higher demands by their citizens, for instance in the area of climate protection. Therefore, every municipality has to consider various economic, social and ecological determinants in its decision-making processes. With respect to public buildings, an economically-oriented cost-benefit-analysis alone is not adequate due to a municipality's role as "consumer and role model". To identify measures with a broader benefit, a multicriteria analysis (MCA) has been used to analyze energy efficiency measures in public buildings for the city of Dortmund. For several years Dortmund has committed itself to implement energy efficiency measures and improve the energy performance of its building stock. Nevertheless, a benchmark analysis still shows a high energy saving potential that cannot be tapped with the existing measures and instruments. Therefore, a package of measures has been developed in close cooperation with the city of Dortmund, ranging broadly from measures of energetic retrofitting and green IT to behavioral change of building occupants. In the MCA these measures have been assessed according to ten different criteria such as innovativeness, cost effectiveness, external costs, CO2 reduction potential, local value or effort of implementation. Three different scenarios ("City as Role Model", "City as Homo Oeconomicus", "City as Climate Protector") show different municipal perspectives. The analysis has shown that the greatest benefit for municipalities, regardless of the municipal perspective, is yielded by measures such as voluntarily enhanced minimum standards for new or for energetic retrofitting of public buildings, the procurement of energy-efficient office equipment, the expansion of heat generation from renewable energies and the usage of private capital in participatory projects like "Solar&Save".

Description: International consensus is growing that a transition towards a low carbon society (LCS) is needed over the next 40 years. The G8, the Major Economies Forum on Energy and Climate, as well as the Ad Hoc Working Group on Long-term Cooperative Action under the United Nations Framework Convention on Climate Change, have concluded that states should prepare their own Low-emission Plans or Low-emission Development Plans and such plans are in development in an increasing number of countries. An analysis of recent long-term low emission scenarios for Germany shows that all scenarios rely heavily on a massive scale up of energy efficiency improvements based on past trends. However, in spite of the high potential that scenario developers assign to this strategy, huge uncertainty still exists in respect of where the efficiency potentials really lie, how and if they can be achieved and how much their successful implementation depends on more fundamental changes towards a more sustainable society (e.g. behavioural changes). In order to come to a better understanding of this issue we specifically examine the potential for energy efficiency in relation to particular demand sectors. Our comparative analysis shows that despite general agreement about the high importance of energy efficiency (EE), the perception on where and how to achieve it differ between the analysed scenarios. It also shows that the close nexus between energy efficiency and non-technical behavioural aspects is still little understood. This leads us to the conclusion that in order to support energy policy decisions more research should be done on energy efficiency potential. A better understanding of its potential would help energy efficiency to fulfil its role in the transition towards a LCS.

Description: The German contribution to limiting global warming to two degrees has to be - as in other developed countries, too - a reduction of 80 to 95 percent of CO2 emissions by 2050 compared to 1990. The project "Low Carbon City Wuppertal 2050" has analysed how such a drastic reduction of CO2 could be achieved on a municipal level in the transportation and residential sector by also working on the land use and material flows dimension. The focus of this paper lies on the space heating in the residential sector. Wuppertal is a city with about 350,000 inhabitants in the West of Germany. According to the CO2 balance (2007) of the city that was adjusted to the year 2010, the emissions that were caused by space heating in the residential sector remained almost the same since 1990. They decreased slightly from 693,000 tons CO2 in 1990 to 691,000 tons in 2010, although final energy use for space heating increased by about 15 percent. But the shift of energy sources especially from coal to gas avoided an increase of emissions. However, the reduction target of 95 percent means that CO2 emissions have to be reduced to 35,000 tons per year until 2050. A reference scenario shows that the city could achieve about 30 percent of the reduction required with the current trend of renewable energy development and energy efficiency measures such as retrofitting the building stock. But looking at the difficult financial conditions of the municipality as well as at the socio-economic situation of the inhabitants it becomes clear that the remaining 65 percent of the target to a 95 percent reduction will be difficult to reach and that innovative measures of energy efficiency and sufficiency1 need to be developed. But which social-ecological effects does the implementation of comprehensive climate protection measures have on the inhabitants of a city? How do people live in a "Low Carbon City"? In this paper qualitative and quantitative scenarios will be developed since the combination of both is promising to show both effects: what share could renewable energies, energy efficiency and sufficiency measures have in reaching the target of 95 percent, and how could life look like in an almost CO2 free city in Germany in 2050.

Description: In 2008, transport accounted for 27% of the world’s total final energy consumption. Currently, we are facing a rapidly expanding transport sector with continually increasing energy consumption. In the future, emerging and developing countries especially will experience an accelerated growth in transport energy demand due to rapid population growth, urbanisation and rising per capita income. The transport sector’s inefficiency and its dependency on oil will become an economic burden for these countries. They will have to face increasing crude oil prices and uncertainties regarding energy security. Thus, there is a need for an efficient transport system and particularly for decision makers in developing and emerging countries to have access to planning advice in order to identify suitable and effective measures for low-energy urban transport. To meet this demand, existing knowledge and measures about energy efficiency in urban passenger transport was compiled and a structured introduction to energy efficiency in transport is provided. The main determinates of an energy-efficient transport system are explained and strategic approaches to increase energy efficiency are outlined. Success factors and barriers for energy efficiency policies are described. The main element of the paper is an overview of different energy efficiency policies and measures for the key actors in energy-efficient transport on local and national levels. A set of measures is assigned to each actor identified. The compilation was adapted to the circumstances in developing and emerging countries and includes examples for successful implementation of several measures. Thus, the document satisfies the need for a comprehensive introduction to energy efficiency in urban transport in developing and emerging countries.
