Greenhouse gas emissions are a major global environmental problem. The majority of nations and independent scientists agree that this must change; the problem comes in the discussion of how this should be done and who should bear the costs. This report aims to analyze the most frequent basic principles of equitable distribution entered in global environmental negotiations. Subsequently an investigation is made about the outcomes these principles would result in if they were applied in 2005, on the member countries of the European Union that joined before 2004. The study is further limited to only analyzing the allocation of emission allowances and carbon emissions. The report is based on the categorization of the basic principles presented by Mattoo and Subramanian (2010) and the model that they generate. By applying emissions data from the selected countries some interesting results are obtained. Although the different principles give rise to highly variable percentage changes, they nevertheless agree on the general direction of the needed change of individual countries.
