Description:
In the negotiations of the Kyoto Protocol, the Brazilian government suggested a method to share emission reductions amongst countries. It was proposed to attribute responsibilities to countries according to the impact of their historical emissions on the surface temperature change and to share emission reduction efforts proportional to their historical contribution.
The approach requires a complex analysis to identify historic emissions and attribute country's contributions to temperature change, which is subject to further research (see MATCH). In general, countries with a longer process of industrialization and thus a longer record of greenhouse gas emissions will have a greater share of responsibility for emission reductions than countries where industrialization started later.
The proposal was originally designed for covering Annex I countries. However, it could theoretically be applied to other countries as well.
