The dynamics of green innovation, environmental policy and energy structure for environmental sustainability; Evidence from AfCFTA countries

Environmental pollution caused by many factors including energy use has been a major problem around the world. A sustainable energy structure can help improve environmental sustainability. The roles of green innovation and environmental policies in determining an effective energy structure and achieving environmental sustainability have gained attention in recent research, but there are gaps to fill. Given the rapid development and unification of Africa to boost economies, this article aims to establish whether or not green innovation and environmental policies have influenced energy structure and environmental sustainability. Thirty-one (31) countries out of the 55 African Continental Free Trade Area (AfCFTA) countries were used in the analysis. The study adopted the Fully modified ordinary least squares (FMOLS) and the Dynamic ordinary least squares (DOLS) models in its analysis. Major empirical results revealed that a 1% increase in green innovations reduces ecological footprints by 0.7% and 1% (DOLS and FMOLS). Also, a percentage increase in environmental policies can reduce ecological footprints by 10.12% (DOLS) and 21.87% (FMOLS). A 1% rise in renewable energy improves their environmental sustainability by 3.26% (DOLS) and 1.82% (FMOLS). A 1% consumption of nonrenewable energy reduces environmental sustainability by 4.59% (DOLS) and 1.55% (FMOLS). These results provide insights into the importance of green innovation, environmental policy, and renewable energy in improving environmental sustainability. Stringent measures and policies to boost green investment, sustainable energies, and environmental sustainability are necessary for the region.
