This article addresses informational barriers to energy efficiency. It is a widely acknowledged result that an energy efficiency gap exists implying that the level of energy efficiency is at an inefficiently low level. Several barriers to energy efficiency create this gap and the presence of asymmetric information is likely to be one such barrier. The article finds that problems of moral hazard and adverse selection indeed can help explain the seemingly low levels of energy efficiency. The theory reveals two implications to policies on energy efficiency. First, the development of measures to enable contractual parties to base remuneration on energy performance must be enhanced, and second, the information on technologies and the education of consumers and installers on energy efficiency must be increased. Finally, it is found that the preferred EU policy instrument on energy efficiency, so far, seems to be the use of minimum requirements. Less used in EU legislation is the use of measuring and verification as well as the use of certifications. Therefore, it is concluded that the EU should consider an increased use of these instruments.
The paper aims to shed light on the methodological challenges of GHG monitoring at local level and to give an overview on current practices. Questions addressed are as follows: How do the methodologies which underlie different GHG inventory tools differ? What are the critical variables explaining differences between inventories? Can different GHG inventory tools be compatible - and/or interoperable - and under which conditions? The first section discusses methodological challenges related to the formation of local GHG inventories. Rather than giving a comprehensive overview on methodological problems, this section mainly highlights some of the central methodological challenges posed by local GHG inventories. This overview identifies critical variables and clarifies concepts that are necessary for the understanding of the subsequent analysis. In section two, some of the most advanced GHG inventory tools are analysed and the most important differences between these tools are highlighted. The paper concludes that the methodologies are not consistent. Local GHG inventories can thus hardly be compared. The paper gives research and policy recommendations towards greater comparability and sketches the requirements of an international protocol on urban GHG inventories.
The Wuppertal Institute for Climate, Environment and Energy and the UNEP/Wuppertal Institute Collaborating Centre on Sustainable Consumption and Production (CSCP) set out to analyse Japanese dematerialisation and resource efficiency strategies within the 3R scope and searched for options of enhancing resource effi ciency strategies, commissioned by the German Federal Environment Agency. A further task of the project was to initiate a policy dialogue including stakeholders, academia, politics and Japanese and European environmental experts. The following paper summarises findings from the analyses, the results of the policy dialogues (Experts Workshop, 6 June 2007 and International Conference, 6 November 2007) and draws conclusions for a potential Japanese-European cooperation on the resource efficiency issue.
This paper focuses on market incentives by the introduction of a construction minerals tax as an example of a resource tax. Currently, various European countries levy taxes or duties on primary construction materials, but a harmonisation of the taxation is not planned. Provided the tax rate has a perceptible price effect, the taxation of a resource can foster a demand management or the reduction of the raw material consumption and the governance of side and secondary effects. A construction minerals tax can target the stimulation of demand for secondary raw materials and recycled products, and - because the reuse of construction and demolition waste has technical limits - a stronger emphasis on the conservation of buildings and infrastructures. This has positive effects on the environment and the innovation efforts and it helps to internalise externalities. Germany, used as a case study in this paper, does not raise any taxes on other raw materials than energy sources at the federal level. For this reason, potential impacts of the introduction of a construction minerals tax will be explored and the results of a simulation will be provided.
This article proposes a policy framework for analysing corporate governance toward sustainable development. The aim is to set up a framework for analysing market evolution toward sustainability. In the first section, the paper briefly refers to recent theories about both market and government failures that express scepticism about the way that framework conditions for market actors are set. For this reason, multi-layered governance structures seem advantageous if new solutions are to be developed in policy areas concerned with long-term change and stepwise internalisation of externalities. The paper introduces the principle of regulated self-regulation. With regard to corporate actors| interests, it presents recent insights from theories about the knowledge-based firm, where the creation of new knowledge is based on the absorption of societal views. The result is greater scope for the endogenous internalisation of externalities, which leads to a variety of new and different corporate strategies. Because governance has to set incentives for quite a diverse set of actors in their daily operations, the paper finally discusses innovation-inducing regulation. In both areas, regulated self-regulation and innovation-inducing regulation, corporate and political governance co-evolve. The paper concludes that these co-evolutionary mechanisms may assume some of the stabilising and orientating functions previously exercised by framing activities of the state. In such a view, the government's main function is to facilitate learning processes, thus departing from the state's function as known from welfare economics.

Die Erstellung von Gemeinschaftsgütern gilt als Problemfall für Märkte und ökonomisch handelnde Individuen. Das vorliegende Buch entwickelt einen neuen Ansatz, in dem Individuen und Unternehmen eine stärkere Rolle einnehmen. Anlass zur Markteuphorie ist jedoch nicht gegeben. Vielmehr ist es Aufgabe der Wirtschaftspolitik, solche Institutionen hervorzubringen, die das Handeln der Akteure auf direkte und indirekte Weise steuern. Dies wird im vorliegenden Buch als wissensbasierter Ansatz bezeichnet. Als Anwendungsbeispiel wird die Kreislaufwirtschaft analysiert. Ein Überblick, der die wesentlichen Thesen und Begründungsstränge enthält, führt in das Buch ein. Im folgenden Teil wird der wissensbasierte Ansatz modellhaft dargelegt. Erörtert werden die Bausteine Lernen, Kognition, Rationalität, deliberative Institutionenentwicklung und Wissen schaffender Wettbewerb. Für die Erstellung von Gemeinschaftsgütern wird ein Eigeninteresse abgeleitet, wenn der technologische und institutionelle Wandel entsprechende Signale generieren. Da beide Größen dem Einfluss von Individuen und Unternehmen unterliegen, entstehen Wechselwirkungen. Die folgenden Kapitel untersuchen den technologischen und institutionellen Wandel im Hinblick auf Potenziale zur Erstellung von Gemeinschaftsgütern. Dabei werden insbesondere neuere Unternehmenstheorien erörtert. Abgeleitet wird eine stufenförmige Grenzkostenfunktion für Institutionen und Organisationen. Ausführlich diskutiert das Buch Implikationen für die Wirtschaftspolitik. Es begründet und operationalisiert die Formulierung offener Ziele. Wirtschaftspolitik wird als Reform und Design von Institutionen konzipiert. Zu diesem Zweck werden zwölf Prüfkriterien formuliert. Dieses Konzept wird anschließend auf die Kreislaufwirtschaftspolitik übertragen. Defizite des Kreislaufwirtschaftsgesetzes (KrW-/AbfG) werden herausgearbeitet. Als Reformen präsentiert das Buch neue Ziele, Wissen generierende Institutionen und ökonomische Anreize. Insgesamt ist das Buch als theorieorientierte Analyse praktischer Probleme geschrieben. Es folgt Ansätzen der Neuen Institutionenökonomik und der evolutorischen Ökonomik. Diese Ansätze werden auf die Analyse der Erstellung von Gemeinschaftsgütern und die Erarbeitung von Lösungsoptionen angewendet.
This paper undertakes a step to explaining the international economics of resource productivity. It argues that natural resources are back on the agenda for four reasons: the demand on world markets continues to increase, the environmental constraints to using resources are relevant throughout their whole life cycle, the access to critical metals could become a barrier to the low carbon economy, and uneven patterns of use will probably become a source of resource conflicts. Thus, the issue is also of relevance for the transition to a low carbon economy. "Material Flow Analysis" is introduced as a tool to measure the use of natural resources within economies and internationally; such measurement methodology now is being harmonized under OECD auspices. For these reasons, the paper argues that resource productivity - that is the efficiency of using natural resources to produce goods and services in the economy - will become one of the key determinants of economic success and human well-being. An empirical chapter gives evidence on time series of resource productivity increases across a number of economies. Introducing the notion of "material flow innovation", the paper also discusses the innovation dynamics and issues of competitiveness. However, as the paper concludes, market barriers make a case for effective resource policies that should provide incentives for knowledge generation and get the prices right.
