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...

Das Ziel der Bundesregierung ist es laut Koalitionsvertrag, "die Erderwärmung auf maximal zwei Grad Celsius zu begrenzen und Deutschlands Vorreiterrolle beim Klimaschutz beizubehalten". Zum Erreichen dieses Ziels sollen die deutschen Treibhausgasemissionen bis zum Jahr 2020 um 40 Prozent...

A world of unequal carbon prices requires measures aimed at preventing carbon leakage. Climate policy imperatives demand that such measures must be compatible with the goal of sending a carbon price signal down the value chain. For carbon intensive materials, the combination of dynamic free...

After the Paris Climate Agreement, it is anticipated that carbon prices will differ across regions for some time. If countries use free allowance allocation as carbon leakage protection, only a fraction of carbon prices are passed through to consumers particularly by carbon intensive materials...

This paper explores whether governments can ban carbon-intensive materials through product carbon requirements. By setting near-zero emission limits for the production of materials to be sold within a jurisdiction, governments would accelerate the phase out of carbon-intensive production...

Nearly every carbon price regulates the production of carbon emissions, typically at midstream points of compliance, such as a power plant. Over the last six years, however, policymakers in Australia, California, China, Japan, and Korea implemented carbon prices that regulate the consumption of...

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...
