The issue of a fair distribution of the burden in the fight against climate change has been the major point of contention since the beginning of the climate negotiations in the 1990s.

Although a number of different approaches of effort distribution emerged in the meantime, many of them reflected the interests of the stakeholders developing them. As a result different weight has been given to different aspects, such as historic responsibility, current emission levels or the capability to reduce these emissions.

This report presents different approaches to the distribution of the mitigation efforts and compares their results to the contributions that some governments submitted to the UNFCCC ahead of the climate conference in Paris.
