In the European Union (EU), a second emissions trading system (EU ETS2) covering buildings, road transport and small energy and industrial installations is expected to be introduced from 2027. Until 2030, however, EU ETS2 will not be a separate pillar of EU climate policy, but will support...

Since 2005, the EU ETS has provided a market-based price signal for European carbon emissions, accompanied by increasing economic research related to this policy instrument. In this paper, we carry out a review of the empirical literature examining allowance price formation. A consensus has...

In this paper we empirically investigate potential determinants of allowance (EUA) price dynamics in the European Union Emission Trading Scheme (EU ETS) during Phase II. In contrast to previous papers, we analyze a significantly longer time series, place particular emphasis on the importance of...

In this paper we examine the influence of foreign direct investment inflows on energy intensities of developing countries empirically. We first show that a simple OLS estimation, as it is found in the literature, suggests energy intensity reductions from FDI inflows, which is consistent with the...

To limit global warming to 1.5°C, vast amounts of CO2 will have to be removed from the atmosphere via Carbon Dioxide Removal (CDR). Enhancing the CO2 sequestration of ecosystems will require not just one approach but a portfolio of CDR options, including so‐called nature‐based approaches...

Any integration of extra carbon dioxide removal (CDR) via terrestrial or marine sink enhancement into climate policies requires accounting for their effectiveness in reducing atmospheric carbon concentration. Different accounting methods have been introduced to quantify the impacts of sink...

Oceans regulate our climate, provide us with natural resources such as food, materials, substances, and energy and are essential for international trade, recreational, and cultural activities. Free access to and availability of ocean resources and services, together with human development, have...

Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as...

Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From...

To stay within the 2êC temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement...
