Brazilian Proposal
Brazilian proposal
The Brazilian proposal is an approach for effort sharing, based on the historical responsibility principle. The approach assigns emission targets to countries based on their responsibility to the current temperature increase, due to their historical emissions. The original approach was proposed by Brazil as an effort sharing mechanism for the developed countries during the negotiations for the Kyoto protocol. The approach has been also analyzed in the global scale in long term emission scenarios, e.g. in den Elzen et al., 2005,[1] who assumed an increasing participation from to the emission reductions.
The approach
In the approach, a global emission pathway is agreed upon, and only countries that pass certain criteria, e.g. Annex I countries or those passing a given threshold in GDP/capita, commit to emission limitations. For these countries the total emissions will be the global target minus the emissions of non-participating countries. The total emissions of participating counties will then be distributed to individual countries in proportion to the effect of their cumulative historical emissions from 1840 on the global average surface temperature.
