Because of large economic and environmental asymmetries among world regions and the incentive to free ride, an international climate Regime with broad participation is hard to reach. Most of the so far proposed Regimes base on an allocation of emission rights that is to be perceived as fair. Yet, there are also some arguments to focus more on the actual welfare implications of different Regimes and to aim for a "fair" Distribution of resulting costs. Using the Cpmputable General Equilibrium model DART, we analyze the driving Forces of welfare implications in different Scenarios where a global Emission target derived from the 2 degree target is reached. These include two Regimes that are often presumed to be "fair", namely a harmonized international carbon tax and a cap and trade System based on the convergence of per capita Emission rights, and additionally an "equal loss" Scenario where welfare losses relative to a Business as usual Scenario are equal for all Major world regions.
We show that "eqaual losses" would mean in particular to compensate for the effects of climate policy on energy markets and e.g. to compensate for the loss of oil revenues as the Organization of Petroleum Exporting Countries (OPEC) argues for.
