Das Ziel eines klimaneutralen Gebäudebestandes bis zur Mitte des laufenden Jahrhunderts erfordert die energieeffiziente Modernisierung fast aller bestehenden Häuser und Wohnungen. Das derzeitige Volumen an privaten und öffentlichen Investitionen reicht jedoch nicht aus, um den Umbau in dieser...

In its 2012 edition of the World Energy Outlook, the International Energy Agency (IEA) produced an Efficient World Scenario (IEA, 2012) to assess how implementing only economically viable energy efficiency measures would affect energy markets, investment and greenhouse emissions (GHG). The IEA...

India has long been regarded as a deal-breaker in international climate negotiations; it was at the summit in Copenhagen that India first abandoned its old strategic line and made a commitment to reduce carbon emissions voluntarily. This shift was accompanied by a proliferation of domestic...

This paper uses a Ramsey model with two types of capital to analyze the optimal transition to clean capital when polluting investment is irreversible. The cost of climate mitigation decomposes as a technical cost of using clean instead of polluting capital and a transition cost from the...

This paper compares the temporal profile of efforts to curb greenhouse gas emissions induced by two mitigation strategies: a regulation of all emissions with a carbon price and a regulation of emissions embedded in new capital only, using capital-based instruments such as investment regulation,...

Improving energy efficiency is often considered to be one of the keys to reducing greenhouse gas emissions. However, efficiency gains also reduce the cost of energy services and may even reduce the price of energy, resulting in energy use rebounding and potential energy use savings being eaten...
