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.

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: The unprecedented challenge of reaching carbon neutrality before mid-century and a large share of it within 2030 in order to keep under the 1.5 or 2 °C carbon budgets, requires broad and deep changes in production and consumption patterns which, together with a shift to renewables and reinforced efficiency, need to be addressed through energy sufficiency. However, inadequate representations and obstacles to characterising and identifying sufficiency potentials often lead to an underrepresentation of sufficiency in models, scenarios and policies. One way to tackle this issue is to work on the development of sufficiency assumptions at a concrete level where various implications such as social consequences, environmental co-benefits, conditions for implementation can be discussed. This approach has been developed as the backbone of a collaborative project, gathering partners in 20 European countries at present, aiming for the integration of harmonised national scenarios into an ambitious net-zero European vision. The approach combines a qualitative discussion on the role of energy sufficiency in a "systemic" merit order for global sustainability, and a quantitative discussion of the level of sufficiency to be set to contribute to meeting 100 % renewables supply and net-zero emissions goals by 2050 at the latest. The latter is based on the use of a dashboard, which serves as a common descriptive framework for all national scenario trajectories and their comparison, with a view to harmonising and strengthening them through an iterative process. A set of key sufficiency-related indicators have been selected to be included in the dashboard, while various interrelated infrastructural, economic, environmental, social or legal factors or drivers have been identified and mapped. This paves the way for strengthening assumptions through the elaboration of "sufficiency corridors" defining a convergent, acceptable and sustainable level of energy services in Europe. The process will eventually inform the potential for sufficiency policies through a better identification of leverages, impacts and co-benefits.

Description: The concept of sufficiency - reducing energy uses beyond technical efficiency - is far-reaching and requires a reflection on human needs, energy services, urban structures, social norms, and the role of policies to support the shift towards lower-energy societies. In recent years, a growing body of literature has been published on energy sufficiency in various disciplines. However, there has been limited exchanges and cooperation among researchers so far, hindering the visibility and impact of this research. This paper presents an assessment of where sufficiency research stands, especially in the perspective of policy-making. It is the first overview paper issued in the context of the newly-founded ENOUGH network - International network for sufficiency research & policy, established in 2017. In the first part, we provide a condensed literature review on energy sufficiency, based on dozens of recent references collected through the network. Through four main themes (the nature of sufficiency, the challenges of modelling it, the barriers to its diffusion, and the approaches to foster it), we summarise the key issues and approaches. We then present what the scholars themselves see as the priorities for future research, promising sufficiency policy options, and key barriers that research should help overcome. We collected their views through a questionnaire completed by more than 40 knowledgeable authors and experts from various disciplines. We finally build on the previous parts to draw some recommendations on how sufficiency research could increase its impact, notably in relation to policy-making.

Description: The Fit for 55 package stipulates a fair, competitive and green transition by 2030 and beyond. As part of this, increasing attention is given to the decarbonisation of the building stock: only 1 % of buildings in Europe are retrofitted each year, a number which must double if the EU is to meet its 2050 targets. Significant energy efficiency investments are needed, whilst the planned expansion of the EU-ETS to the building sector in 2026 will likely pass the carbon cost onto the consumer. This will increase the cost burden placed on low-income households, exacerbating energy poverty, if these two strategies are not counterbalanced by adequate policies and support mechanisms. The European Private Rented Sector (PRS) is often side-lined by policymakers when implementing energy efficiency policies to tackle energy poverty. As many as 1 in 10 Europeans spend 40 % or more of their income on housing costs, with those in the PRS struggling with energy-related problems, such as poor energy efficiency and maintenance, to a much greater degree than the general population. Understanding these challenges and creating targeted policies is of critical scientific and policy importance. To date, a pan-European policy on how to address energy poverty and energy efficiency improvements in the PRS is lacking; current European Union instruments to address such issues (including the Fit for 55, and the Clean Energy Package that preceded it) lack a dedicated approach towards the complex structural issues embedded in the European PRS. What is more, there is a limited understanding of the character of energy poverty in such residential dwellings, as well as policies to address energy injustices. We therefore examine current and historical disparities in energy poverty between the EU's PRS tenants and the general population by analysing a variety of quantitative indicators which reflect different dimensions of energy poverty. We then take stock of the policy landscape, identifying energy efficiency policies tailored to alleviate energy poverty in the PRS and common challenges. We subsequently interrogate possible solutions, drawing on existing good practice policies. In so doing, we aim to reduce the sector's political invisibility by addressing the lack of disaggregated, targeted data and dismantling barriers that currently lead to the PRS being disproportionately affected by energy poverty.

Description: Wie gestalten wir Wohlstand zukunftsfähig - obwohl es immer weniger Erwerbsarbeit für alle gibt? Wie müssen Wettbewerb und Kooperation zusammenwirken? Wie verbessern wir die Balance zwischen den Marktgütern und den marktfreien Gütern, die heute so stark gefährdet erscheint? Marktfreie Güter wie menschliche Zuwendung, selbstbestimmte Lebensführung, gesellschaftliche Integration und soziale Verantwortlichkeit sind nicht zu kaufen. Sie werden in Familie und Gruppe, in Nachbarschaft und bürgerschaftlichem Engagement hervorgebracht. Und sie sind nötiger denn je - zumal in den städtischen Räumen. Ausgehend von empirischen Untersuchungen, zeichnen die Autoren die Ansätze und Perspektiven einer Tätigkeitsgesellschaft, in der sich Erwerbs- und Subsistenzwirtschaft produktiv ergänzen.

Description: Europa braucht eine neue Fortschrittsvision. Eine Energiewende hat dieses Potenzial. Sie kann der "Europäischen Idee" einen zukunftsorientierten Inhalt geben. Das Ziel für 2050 ist klar: ein Europa ohne fossile und nukleare Energie! Das ist keine Utopie. Studien, Beschlüsse der EU und einiger Mitgliedsländer belegen, dass diese Vision machbar und mit vielen Vorteilen verbunden ist: mehr Jobs, mehr Versorgungssicherheit, weniger vorzeitige Todesfälle durch Luftverschmutzung, Abbau von Ressourcenkonflikten, sinkende Energiekosten. Neue grüne Leitmärkte für erneuerbare Energien und Ressourceneffizienz entstehen. Eine europäische Energiewende erfordert eine Allianz, idealerweise angefeuert durch die Nachbarn Frankreich und Deutschland. Viele hoffen auf Deutschland als Treiber von Atom- und Kohleausstieg. Aber "revolutionäre Ziele" zu beschließen ist nicht genug: Sie endlich umzusetzen - darauf warten Deutschland und Europa. Dieses Buch zeigt, welche konkreten Schritte diese Fortschrittsvision voranbringen werden.

Description: Die Grenzen des Verkehrswachstums sind erreicht. Klimaschutz und Lebensqualität sind wichtiger als hochgerüstete Autoflotten, die für Millionen Menschen ohne Auto Belastungen und Mobilitätsnachteile bedeuten. Notwendig ist eine radikale sozial-ökologische Transformation des Verkehrssystems: Ausbau und Förderung des Umweltverbundes aus ÖPNV, Schiene, Sharing-Systemen, Rad- und Fußverkehr - das sind bekannte Strategieelemente, die aber durch die herrschende Privilegierung des Autos ausgebremst werden. Dabei hat das Leitbild der autogerechten Stadt längst ausgedient. Entfesselte Automobilität frisst immer mehr Natur und Lebensqualität. Ziel muss es sein, nachhaltige Mobilität zu sichern, Verkehrsgerechtigkeit zu schaffen und die Hälfte der Autoflotte überflüssig zu machen. Und die Zukunft ist bereits unterwegs. Längst planen viele Städte eine menschengerechtere Mobilität: in Paris, Kopenhagen, Freiburg und anderswo. Unterstützt durch eine engagiertere Verkehrspolitik von Bund und EU, kann aus der kommunalen Verkehrsbewegung eine nachhaltige Mobilität für alle in Stadt und Land werden. Neue grüne Geschäftsfelder und gute Arbeit für moderne Mobilitätsdienstleistungen sind dabei Kernelemente. Mit den riesigen Maßnahmenprogrammen wegen der Corona-Pandemie und für den Klimaschutz kann ein gestaltender Staat die Chancen der Verkehrswende erschließen. Für dieses Gemeinschaftswerk können Wählermehrheiten gewonnen werden.

Description: Nie gab es mehr zu tun. Unsere Wirtschaft braucht nicht nur technische, sondern auch soziale und kulturelle Innovationen. Etablierte Wirtschaftsförderung beschränkt sich meist auf klassische gewerbliche Unternehmen und strebt nach Wettbewerbsfähigkeit und Wachstum. Das Konzept der Wirtschaftsförderung 4.0 geht darüber hinaus und betrachtet die gesamte Wirtschaft einer Stadt oder Region. Es ergänzt die klassischen Strategien und zielt darauf ab, lokale und regionale Wirtschaftsstrukturen zu stärken. Auch private und öffentliche Haushalte, Vereine und soziale Initiativen werden dabei berücksichtigt. Wirtschaftsförderung 4.0 initiiert so neue Wertschöpfung vor Ort, eröffnet lokale Investitionsmöglichkeiten, bindet regionale Kaufkraft, entfaltet neue Wirtschaftsideen, fördert Kooperationen und stärkt lokale Vielfalt. Zudem fördert sie Ressourcengerechtigkeit und Klimaschutz. Das Buch stellt diese innovative Wirtschaftsförderung vor, die die regionale und lokale Wirtschaft stabilisiert und Regionen dadurch widerstandsfähiger gegen globale Krisen macht.

Description: Dieses Buch macht Schluss mit umweltmoralischen Appellen! Es zeigt: Wir können verantwortungsvoll leben, ohne uns tagtäglich mit Klimawandel oder Massentierhaltung befassen zu müssen.
