Sechs Punkte für eine effiziente grüne Transformation
Reint E. Gropp, Oliver Holtemöller
IWH Policy Notes,
No. 2,
2024
Abstract
Die grüne Transformation, verstanden als ein Prozess, Energie zunehmend treibhausgasneutral zu erzeugen, kann mit marktwirtschaftlichen Instrumenten und dafür erforderlichen Rahmenbedingungen kostengünstiger umgesetzt werden als mit staatlicher Steuerung des Energieverbrauchs und der Energieerzeugung. Kosteneffizienz ist von entscheidender Bedeutung für die Bereitschaft und Fähigkeit der Bevölkerung, die Lasten der Transformation zu tragen, und für eine gerechte Verteilung der Lasten.

Production bottlenecks delay recovery
The German recovery made good progress over the summer 2021. However, bottlenecks in sea transport and the production of intermediate goods are weighing on world trade. The rise in raw material prices has prompted inflation rates to spike, and an increase in new infections is clouding the outlook again. A weak final quarter is therefore to be expected. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 2.2% in 2021 and 3.6% in 2022 (East Germany: 1.8% and 2.8%).

Regulation, Innovation and Technology Diffusion - Evidence from Building Energy Efficiency Standards in Germany
Makram El-Shagi, Claus Michelsen, Sebastian Rosenschon
Discussionpapers des DIW Berlin,
No. 1371,
2014
Abstract
The impact of environmental regulation on technology diffusion and innovations is studied using a unique data set of German residential buildings. We analyze how energy efficiency regulations, in terms of minimum standards, affects energy-use in newly constructed buildings and how it induces innovation in the residential-building industry. The data used consists of a large sample of German apartment houses built between 1950 and 2005. Based on this information, we determine their real energy requirements from energy performance certificates and energy billing information. We develop a new measure for regulation intensity and apply a panel-error-correction regression model to energy requirements of low and high quality housing. Our findings suggest that regulation significantly impacts technology adoption in low quality housing. This, in turn, induces improvements in the high quality segment where innovators respond to market signals.

Towards a Theory of Climate Innovation - A Model Framework for Analyzing Drivers and Determinants
Wilfried Ehrenfeld
Journal of Evolutionary Economics,
2013
Abstract
In this article, we describe the results of a multiple case study on the indirect corporate innovation impact of climate change in the Central German chemical industry. We investigate the demands imposed on enterprises in this context as well as the sources, outcomes and determining factors in the innovative process at the corporate level. We argue that climate change drives corporate innovations through various channels. A main finding is that rising energy prices were a key driver for incremental energy efficiency innovations in the enterprises’ production processes. For product innovation, customer requests were a main driver, though often these requests are not directly related to climate issues. The introduction or extension of environmental and energy management systems as well as the certification of these are the most common forms of organizational innovations. For marketing purposes, the topic of climate change was hardly utilized so far. As the most important determinants for corporate climate innovations, corporate structure and flexibility of the product portfolio, political asymmetry regarding environmental regulation and governmental funding were identified.

The Effects of Building Energy Codes in Rental Housing: The German Experience
Claus Michelsen, Sebastian Rosenschon
Economics Bulletin,
No. 4,
2012
Abstract
This paper investigates the effect of building energy codes on housings' real energy consumption. We argue that building codes should have a twofold effect: lower levels of energy consumption after its implementation and decreasing energy requirements over time, because tighter building codes induce technical progress in the construction sector. We find evidence for both aspects. Based on a large and unique sample of energy certificates from Germany, this study is the first that deals with the empirical effects of energy efficiency standards in apartment/rental housing. Moreover, it is the first, which includes different stages of regulation.

A Model for the Valuation of Carbon Price Risk
Henry Dannenberg, Wilfried Ehrenfeld
Antes, R.; Hansjürgen, B.; Letmathe, P.; Pickl, S. (Hrsg.), Emissions Trading - Institutional Design, Decision Making and Corporate Strategies (Second Edition),
2011
Abstract
Die Modellierung des CO2-Zertifikatepreisrisikos ist ein wichtiger Teilaspekt eines ganzheitlichen Managements von mit dem Emissionshandel verbundenen Unternehmensrisiken. Das Papier diskutiert ein Preisbildungsmodell, auf dessen Grundlage das Zertifikatepreisrisiko bewertet werden kann. Es wird davon ausgegangen, dass der Zertifikatepreis durch die erwarteten Grenzvermeidungskosten der Handelsperiode determiniert wird und stochastisch um dieses Niveau schwankt. Dieses Verhalten wird mit einem Mean-Reversion-Prozess modelliert. Aufgrund von Unsicherheiten bezüglich künftiger Umweltzustände ist jedoch zu vermuten, dass innerhalb einer Handelsperiode durch das Bekanntwerden neuer Informationen sprunghafte Veränderungen der erwarteten Grenzvermeidungskosten auftreten können, womit sprunghafte Verschiebungen des erwarteten Preisniveaus einhergehen. Neben der ParameterSchätzung ist es daher auch ein Ziel der Arbeit, den Mean-Reversion-Prozess so zu modifizieren, dass solche sprunghaften Veränderungen des erwarteten Reversion-Niveaus abgebildet werden können.
