Nevertheless, most of the existing evidence focuses on developed regions. In this paper, we analyse the evolution of the ecological footprint for the African continent, during 1970–2018. The Phillips and Sul (2007, 2009) panel club convergence approach is carried out. This framework allows us to test the null hypothesis of absolute convergence for a pool of data and to identify groups of countries that converge to the same steady state. Our results offer important insights into the emissions catch-up exhibited by these countries, but do not support the hypothesis that all countries of the African region converge to a single equilibrium. The empirical results strongly support the existence of two convergence clubs. Our empirical findings have important implications for African policymakers in terms of mitigation policies, as the results suggest that a common environmental policy across the entire African continent is sub-optimal, since these regions have heterogeneous behaviours and move towards different equilibriums. info:eu-repo/grantAgreement/ES/DGA/S32-20R info:eu-repo/grantAgreement/ES/MCIU/FPU20-03564 info:eu-repo/grantAgreement/ES/MICINN/PID2019-108348RA-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.2 2023 ECONOMICS 341 / 600 = 0.568 2023 Q3 T2 0.376 2023 Economics and Econometrics 2023 Q3 2.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Molina, José Alberto Universidad de Zaragoza (orcid)0000-0002-9437-4606 4000 415 Universidad de Zaragoza Dpto.
