Carbon and inequality: From Kyoto to Paris Trends in the global inequality of carbon emissions (1998-2013) & prospects for an equitable adaptation fund World Inequality Lab

Abstract : This study presents evolutions in the global distribution of CO2e emissions (CO2 and other Green House Gases) between world individuals from 1998 and 2013 and examines different strategies to finance a global climate adaptation fund based on efforts shared among high world emitters rather than high-income countries. To this end, we combine data on historical trends in per capita country-level CO2e emissions, consumption-based CO2e emissions data, within-country income inequality and a simple income-CO2e elasticity model. We show that global CO2e emissions inequalities between individuals decreased from Kyoto to Paris, due to the rise of top and mid income groups in developing countries and the relative stagnation of incomes and emissions of the majority of the population in industrialized economies. Income and CO2e emissions inequalities however increased within countries over the period. Global CO2e emissions remain highly concentrated today: top 10% emitters contribute to about 45% of global emissions, while bottom 50% emitters contribute to 13% of global emissions. Top 10% emitters live on all continents, with one third of them from emerging countries.
