Abstract
The introduction of the European emissions trading system means that those enterprises taking part have a new planning risk factor to consider – emissions allowance prices. In this article, we analyse how risk emerging from emissions trading can be considered in the stochastic income statement planning of corporations. Therefore, we explore which planned figures are affected by emissions trading. Moreover, we show an approach that models these positions in a planned profit and loss account, taking into account uncertainties and dependencies. Consequently, this model provides a basis for risk assessment and investment decisions in the uncertain environment of emissions trading.

Klimarisikomanagement mit dem CO2-Navigator
Edeltraud Günther, C. Manthey, G. Weber, M. Nowack, Wilfried Ehrenfeld, Henry Dannenberg
HMD - Praxis der Wirtschaftsinformatik,
2010
Abstract
Die Software CO2-Navigator wendet den Realoptionsansatz und den Risikomanagementprozess auf den unternehmerischen Umgang mit dem Klimawandel an. Er richtet sich in erster Linie an emissionsintensive, kleine und mittlere Unternehmen ist jedoch auch in größeren Unternehmen, die beispielsweise eine eigene „Sustainability“-Abteilung unterhalten, anwendbar. Der Wertbeitrag des Softwaretools besteht darin, dass es die Aspekte Klimastrategie, quantitative Bewertung von Klimaschutzinvestitionen sowie Emissionsrechtemanagement vereint. Es kann im Unternehmen in Bereichen strategisches Management, regulatorisches Management, Energie- und Umweltmanagement, Technologiemanagement sowie Controlling Anwendung finden. Der spezielle Wertbeitrag dieses Artikels liegt in der Verknüpfung von Klimarisikomanagement und Realoptionsansatz sowie in der Darstellung des CO2-NAVIGATORs vor dem Hintergrund seiner Entwicklung im Sinne konstruktionsorientierter Forschung.

Stochastic Income Statement Planning and Emissions Trading
Henry Dannenberg, Wilfried Ehrenfeld
Abstract
Since the introduction of the European CO2 emissions trading system (EU ETS), the
development of CO2 allowance prices is a new risk factor for enterprises taking part in this system. In this paper, we analyze how risk emerging from emissions trading can be considered in the stochastic profit and loss planning of corporations. Therefore we explore which planned figures are affected by emissions trading. Moreover, we show a way to model these positions in a planned profit and loss account accounting for uncertainties and dependencies. Consequently, this model provides a basis for risk assessment and investment decisions in the uncertain environment of CO2 emissions trading.

Forecasting the CO2 certificate price risk
Henry Dannenberg, Wilfried Ehrenfeld
IWH Discussion Papers,
No. 5,
2008
Abstract
Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices. We assume that the certificate price is determined by the expected marginal CO2 abatement costs prevailing at the current trade period and stochastically fluctuates around the respective level as returned from the mean reversion process. Due to uncertainties about future environmental states we suppose that within one trade period, erratic changes in the expected marginal abatement costs may occur leading to shifts in the price level. The aim of the work is to model the erratic changes of the expected reversion level and to estimate the parameters of the mean reversion process.

The European Emissions Trading System: What Have We Learned so Far?

Wirtschaft im Wandel,
No. 3,

Abstract
The IWH occupies with the consequences of the emission trading for the effected companies. The first period of the European Emission Trading System was conceived as a learning phase during which two problems occurred: The first and most obvious one was the surplus of certificates. The incentives to invest in the mitigation of CO2 can therefore be considered to be low. The second problem resulted from the allocation which was entirely for free. While electricity customers had to bear the main financial burden, electricity producers profited as the certificate-prices were obviously added to the electricity-prices as opportunity costs. The analysis comes to the conclusion that it was right to shorten the amount of certificates on the EU-level for the second trade period and to establish the partly sales or auctioning of certificates in German legislation. Furthermore, the simplification of the allocation method in Germany can be considered to be a progress.
