Abstract
This study investigates the relationship between different types of within-country inequality reduction and CO2 emissions using panel data in 156 countries from 1995 to 2020. Using fixed effects panel and quantile regression techniques, we report estimates that indicate that predistribution (pre-tax inequality reduction) increases carbon emissions less than redistribution (post-tax inequality reduction measured as the difference between pre and post-tax inequality). Moreover, we differentiate between the effect of predistribution and redistribution on production-based and consumption-based emissions. Countries that produce more carbon-intensive products than they consume and low emitting countries face the highest trade-off between predistribution and decarbonization. By contrast, reduction in inequality through predistribution does not affect per capita consumption-based CO2 emissions among the highest emitting countries. These findings call for international cooperation and public policies aimed at a more equitable primary income distribution to achieve joint inequality and reduction of carbon emissions.
Le conflit au Moyen-Orient a rappelé le besoin d’accélérer la transition énergétique, mais le besoin d’investissements massifs concerne bien autres domaines. Comment les financer, alors que la pression sur les finances publiques s’accroît et que de nombreux projets ne sont pas assez rentables pour attirer spontanément les investisseurs privés ?
