Equity in international greenhouse gases abatement scenarios: A multicriteria approach

The climate change problem involves long-term global efforts through sustainable development. The international burden sharing of greenhouse gases (GHG) abatement constitutes a controversial debate. Equity is an important issue to be considered in the mitigation policies to insure the participation of as many developing countries as possible. The main purpose of this research is to allocate equitable international GHG emission entitlements using several criteria. There are many equity definitions and some are conflicting. A dynamical multicriterion method is proposed to compare various alternatives and to find a compromise solution. If the decision-making process can take into account interests and preoccupations of every country, significant progress could be made to achieve a world concensus. Several burden sharing schemes are proposed. Then, modelling abatement scenarios using the TIMES world energy model will allow us to determine the cost-effectiveness opportunities.
