Do Environmental Tax Revenues Reduce Co₂ Emissions? Evidence From Oecd Countries Using Two-way Fixed Effects

Auteurs : Abderrahim Nadia .

Résumé

This study seeks to measure the impact of environmental tax revenues on reducing CO₂ emissions within OECD countries , highlighting the role of renewable energy consumption as a mediating variable and the quality of governance as a moderating variable. Panel data covering 38 OECD countries over the 2010-2023 period were analyzed to estimate a moderated mediation model in the first stage within a two-way fixed-effects framework, the data were processed using Python . The results showed that environmental tax revenues are inversely related to renewable energy consumption whilst renewable energy consumption leads to a reduction in CO₂ emissions. High levels of governance significantly moderate the relationship between environmental tax revenue and renewable energy and unlike expectations, this effect was positive. These findings suggest that the environmental effectiveness of tax revenue depends as much on the quality of institutions as it does on the design of the tax policy itself
