Based on the political support function model by Hillman (1982), we consider the choice of policy instruments in environmental regulation. More specifically, we extend the Hillman model so that it can incorporate the connection between the relative strength of lobby groups, the chosen level of...

Sechs Jahre nach der Verabschiedung des Kyoto-Protokolls im Dezember 1997 sind die meisten Länder der internationalen Staatengemeinschaft noch weit von den damals verabredeten Klimaschutzzielen entfernt. Im Jahre 2001 lagen die Treibhausgas-Emissionen in den OECD-Ländern, die im...

In this paper, we use the two region CETA-M model to explore some related issues raised by the current interest in CO2 concentration targets as a possible climate change policy objective. First, we identify possible cost and benefit assumptions that would make particular concentration ceilings...

Stabilization of greenhouse gases at sustainable levels is the objective of the FCCC. Strategies to achieve this aim have been the object of intense debate. This paper focuses on one emissions trading system under scrutiny, Joint Implementation (JI). The basic premise of JI is that one nation...

When dealing with multiple greenhouse gases, we need some way to establish equivalence among gases. The Intergovernmental Panel on Climate Change (IPCC) has suggested the use of global warming potentials (GWPs) for making such trade-offs. We begin by examining the implications of such an...

Sachzwänge im internationalen Klimaschutz: 1. Weltweit wirksame Begrenzung von Emissionen, 2. Nutzung der Ressource muss einen Preis haben, um Anreiz für sparsamen Umgang zu geben, 3. Pro-Kopf-Lösung (auch von Bundeskanzlerin Merkel gefordert), damit Indien und China mitmachen....

Die internationale Klimakonferenz von Paris stellt einen weiteren Versuch dar, für die Bereitstellung des globalen öffentlichen Guts Klimaschutz die notwendige Kooperation zwischen den verhandelnden Staaten zu organisieren. Dabei geht es im Wesentlichen um die Verteilung der damit verbundenen...

We propose a global refunding scheme as a new international approach to addressing climate change. A global refunding system allows each country to set its carbon emission tax, while aggregate tax revenues are partially refunded to member countries in proportion to the relative emissions...

We propose a blueprint for an international emission permit market such as the EU trading scheme. Each country decides on the amount of permits it wants to offer. A fraction of these permits is grandfathered, the remainder is auctioned. Revenues from the auction are collected in a global fund...
