The aim of the European Emissions Trading Scheme is to reduce environmentally harmful greenhouse gas emissions and incentivize investment in low-emission technologies. However, in recent years, a large surplus of emission allowances has accumulated, primarily as a result of an unexpected...

The heating market plays a key role in achieving the Federal Government's energy and climate policy objectives. In particular, major savings need to be made in heating residential buildings if the majority of buildings are to be climate-neutral by 2050. In light of this, DIW Berlin and ista...

To date, the European Union has been at the forefront of international climate protection. But there are now a number of other countries also pursuing a proactive energy and climate policy. They are increasingly investing in renewable energies, exploiting potential energy efficiencies in...

In the European Emission Trading scheme the supply of allowances exceeds emissions - cumulating, according to our estimates, in a surplus of 2.7 billion tonnes by 2013/2014. We find that initially the surplus was acquired by power companies so as to hedge future carbon costs. As the surplus...

In the European Emissions Trading System, power generators hold CO2 allowances to hedge for future power sales. First, we model their aggregate hedging demand in response to changes in expectations of future fuel, carbon and power prices from forward prices. This partial equilibrium analysis is...

Zwischen 2002 und 2007 verabschiedete die Bundesregierung die Nationale Nachhaltigkeitsstrategie und das Integrierte Energie- und Klimaprogramm. Beide Programme enthalten klare energie- und klimapolitische Zielsetzungen: So sollen die Treibhausgasemissionen bis zum Jahr 2020 um 40% gesenkt...

Between 2002 and 2007, Germany introduced its National Strategy for Sustainable Development and its Integrated Climate Protection Program, which both defined clear energy and climate-related objectives, setting an emissions reduction trajectory of 40% below the 1990 level by 2020. This spurred...

The energy transition will require considerable increases in energy efficiency, particularly in residential buildings. Financial support mechanisms, information and adviceprograms and dedicated training and certification of craftsmen are already in place to stimulate energy efficiency...

Die Energiewende erfordert erhebliche Steigerungen der Energieeffizienz vor allem in Wohngebäuden. Um die Investitionstätigkeit zu steigern, gibt es bereits zahlreiche Förderinstrumente, Kampagnen und in erheblichem Umfang öffentliche Fördermittel. Gleichwohl wird die notwendige jährliche...

We examine under which conditions a cap-and-trade mechanism can deliver a dynamically efficient abatement pathway and contribute to a robust investment framework. For this we develop a numerical dynamic partial-equilibrium model that includes differentiated objective functions of different...
