Abstract

This paper focuses on the equity aspects of international burden sharing for global CO2 emission stabilization. It first summarizes and classifies equity principles proposed in the published literature of the field. Of these, the authors selected three major equity principles, i.e., "egalitarian equity", "horizontal equity", and "proportional equality" (often referred to also as "sovereign equity") to carry out a detailed examination of two sets of quantitative emission entitlements, which are based on two burden-sharing rules, i.e., the "equal emissions per capita" approach and the "carbon intensity" approach. The two burden-sharing rules were chosen as not only particularly popular, but also because their application results in distinctly different burden sharing among countries.

To make the two rules comparable, we used a global carbon-emission path until the year 2050 that leads to an atmospheric CO2 concentration of 550 ppm. We then used the two rules for allocating the global emissions described by that path to allocate carbon emission entitlements to 67 countries and 9 world regions. In general, developing countries receive relatively higher entitlements under the equal emissions per capita approach whereas industrialized countries are relatively better off under the carbon intensity approach.

In some countries and regions, emission entitlements as calculated by any of the two burden-sharing rules are so low that it would be unrealistic to assume that actual emissions can be limited to the emission entitlements assigned to them without using flexibility mechanisms such as those defined in the Kyoto Protocol. In this sense, the calculated entitlements can be also interpreted as the initial allocation of tradable emission allowances of countries or regions. Nonetheless, we considered any numerical determination of resulting carbon trade flows to be outside the scope of our paper.
