The economic assessment of low-carbon energy options is the primary step towards the design of policy portfolios to foster the green energy economy. However, today these assessments often fall short of including important determinants of the overall cost-benefit balance of such options by not including indirect costs and benefits, even though these can be game-changing. This is often due to the lack of adequate methodologies.
The purpose of this paper is to provide a comprehensive account of the key methodological challenges to the assessment of the multiple impacts of energy options, and an initial menu of potential solutions to address these challenges.
The paper first provides evidence for the importance of the multiple impacts of energy actions in the assessment of low-carbon options.
The paper identifies a few key challenges to the evaluation of the co-impacts of low-carbon options and demonstrates that these are more complex for co-impacts than for the direct ones. Such challenges include several layers of additionality, high context dependency, and accounting for distributional effects.
The paper continues by identifying the key challenges to the aggregation of multiple impacts including the risks of overcounting while taking into account the multitude of interactions among the various co-impacts. The paper proposes an analytical framework that can help address these and frame a systematic assessment of the multiple impacts.
The paper presents the results of an ex-ante evaluation of the economy-wide benefits that may be achieved through the implementation of the 20-year Energy Efficiency Action Plan (EEAP) in Thailand. The objective of the EEAP is to reduce energy intensity by 25 % in 2030 compared to 2010. This is to be reached by reducing the projected energy consumption by 20 % or 38 Mtoe until 2030. We have specified an analytical framework, which allows for a calculation of the overall energy cost savings, energy import cost reductions and reduced CO2 emissions. Moreover, we calculated the induced energy efficiency investments, employment effects and impacts on governmental budget. The evaluation shows that an effective implementation of the plan may lead to a reduction in energy expenditure of 37.7 billion EUR by 2030. Moreover, the EEAP-induced energy savings will significantly reduce the greenhouse gas emissions as well as Thailand’s energy import costs and generate private investment in energy efficiency of about 5 billion EUR annually in 2030, which in turn may lead to about 300,000 new jobs. The size of the net impact of the plan on Thailand’s governmental budget is uncertain due to positive and negative effects on corporate and income tax revenues, expenses for unemployment benefits, governmental energy consumption, expenses for energy subsidies and energy tax income.
Cleaner vehicles
(2016)
This review of sources has assessed existing evidence for economic benefits arising from innovations or interventions that aim to improve the environmental performance of vehicles - such as enhancements to engine and vehicle technologies or improved fuels. It is designed to support cities in their decision making and measure selection process. The article is one of 22 reviews published in this volume.
Marketing and rewarding

This review of sources has assessed existing evidence for economic benefits arising from marketing / social marketing and rewards-based schemes encouraging greater use of more sustainable modes and travel behaviours. It is designed to support cities in their decision making and measure selection process. The article is one of 22 reviews published in this volume.
Stockholm, Hamburg, Vitoria-Gasteiz, Nantes, Kopenhagen, Bristol, Ljubljana, Essen - das sind die Europäischen Umwelthauptstädte der Jahre 2010 bis 2017. Sie wurden in einem jährlichen europaweiten Wettbewerb von der Europäischen Kommission als Vorbildstädte ausgewählt. Sie zeigen aus Sicht der Europäischen Kommission, wie eine zukunftsfähige, umweltorientierte Stadtentwicklung im 21. Jahrhundert aussehen kann. Welchen EU-Benchmark markieren diese acht Städte für die Gestaltung eines klimaschonenden Personenverkehrs in der Stadt?
Global climate
(2016)
This article summarises the main outcomes of the Lima UN Climate Conference (COP20 / CMP10). It starts with the discussions under the Durban Platform on developing a new comprehensive climate agreement and increasing short-term ambition and subsequently covers the issues relating to near-term implementation of previous decisions in the areas of transparency, reducing emissions from deforestation and forest degradation, loss and damage, adaptation, finance, and carbon markets.
On 12 December 2015, the Parties to the UNFCCC adopted the "Paris Agreement". With this step, the world community has agreed on a collective and cooperative path to fight human-induced climate change: After 25 years of UN climate diplomacy, the world's governments have for the first time in history negotiated a treaty which envisages climate action by all nations. The Agreement sets the world on a path that might lead to a decarbonised economy in the second half of the century. Researchers from the Wuppertal Institute have observed COP 21 and elaborated a detailed analysis of the results. The assessment provides an overview of the most important negotiation outcomes, assesses their results as well as shortfalls and provides an outlook of the next steps needed to implement the Paris Agreement's goals and to set the world firmly on a non-fossil based development path.
The so-called "Semesterticket" is a special tariff for university students in Germany which enables them to use public transport in the area of their university. Semester tickets are financed in solidarity by the students: If a university runs a semester ticket, all students automatically have to buy a ticket for one semester (6 months), regardless of whether they want to use public transport or not. In return, the students can use public transport in the area of their university for a very low semester contribution as much as they want without purchasing any extra tickets. In Germany, the first semester ticket was introduced 25 years ago in Darmstadt (1991) as a result of student initiatives. Today, most German universities run a semester ticket.
This article describes the concept of semester tickets in Germany, their development over the time and presents empirical research data on student acceptance and the effects of semester tickets on mode shift to public transport and the reduction of car ownership.
Energiearmut gezielt lindern
(2016)
Die Öl- und Gaspreise sinken seit einigen Jahren wieder. Kann die aufkeimende deutsche Debatte um Energiearmut damit ad acta gelegt werden? Nein, die derzeitige Niedrigpreisphase sollte vielmehr genutzt werden, um sich auf wieder steigende Energiepreise vorzubereiten. Daher gilt es, alternative Ansätze zu diskutieren, um energiearme Haushalte besser als bislang zu identifizieren und zu adressieren. Energiearmut ist ein vielschichtiges Phänomen, das insbesondere im Bereich der Heizkosten noch viel Forschungs- und Handlungspotenzial hat.
Die Entwicklung Wolfsburgs ist eng mit dem Unternehmenserfolg der Volkswagen AG verbunden. Die strategische Allianz war lange Zeit für beide Seiten vorteilhaft, führte jedoch zu Abhängigkeiten. Zum einen trug die Verkehrs- und Stadtplanung zu einer autogerechten Stadtentwicklung bei. Zum anderen ist die kommunale Haushaltslage vom unternehmerischen Erfolg VWs abhängig. Dieser Beitrag zeichnet die Verbindung zwischen Kommunalplanung und Unternehmensinteressen nach und zeigt wie ein möglicher Paradigmenwechsel im Bereich der Stadt- und Verkehrsentwicklung aussehen könnte.
