The Kyoto Protocol: Regional and Sectoral Contributions to the Carbon Leakage

Carbon dioxide emissions abatement in a grou p of countries can result in increased emissions in non-abatingcountries. This effect has been referred to as carbon leakage. The Kyoto Protocol calls for a number of industrialized countries to limit their emissions while other countries have no abatement commitments. This paper assesses the sectoral and regional determinants of the leakage in a static multi-sector, multi-regional computable general equilibrium model. In baseline estimates based on our model, the Kyoto Protocol leads to a carbon leakage rate of 10 percent. A decomposition technique is applied which attributes increases in CO2 emissions by non-participating countries to specific sectors in the abating countries. This information is important for the debate on the tax exemptions for certain industries in the participating countries as it provides information for the most- and least leakage contributing sectors of the economy. Additional calculations indicate the need for caution in the carbon tax design. Exemptions of any sector from a carbon tax are not justifled because they lower welfare in a region. The degree of sectoral and regional data disaggregation, and international capital mobility do not change the leakage rate significantly. Fossil-fuel supply elasticities and trade substitution elasticities are crucial determinants for projecting the total world emissions of CO2.
