Innovation is considered an effective tool for fighting CO₂ emissions as it enhances energy efficiency and cleaner production. However, it has received limited attention in the context of Africa. Therefore, the study examines the nonlinear link between innovation and CO₂ emissions in nine (9) African nations from 1990-2016 at both panel and individual country level. The cross sectional augmented Dickey Fuller (CADF) panel unit root test affirmed the stationarity of the variables. Westerlund and Johansen cointegration tests established a long-run link amongst the variables. The study employed fixed effect model and generalized method of moments for the panel and ordinary least square for individual country. The results validated an inverted U-shape relationship between innovation and CO₂ emission at panel level and in Mauritius, Egypt, and South Africa. Renewable energy use lessens CO₂ emissions at the panel level. Human capital decreases CO₂ emissions at the panel and in some individual countries. Moreover, both pollution haven hypothesis and pollution halo effect were confirmed. Similarly, at the panel level Environmental Kuznets Curve was confirmed in 4 out of 9 countries. Our findings suggest that regional integration and assimilation of innovation into all stages of development for green growth should be pursued.

创新被认为是对抗CO ₂排放的有效工具，因为它可以提高能源效率和清洁生产。但是，它在非洲方面受到的关注有限。因此，本研究探讨了创新与CO ₂之间的非线性联系。从1990年至2016年，在面板和单个国家/地区中，有九（9）个非洲国家的温室气体排放量。横截面增强Dickey Fuller（CADF）面板单位根检验确认了变量的平稳性。Westerlund和Johansen协整检验在变量之间建立了长期的联系。该研究采用固定效应模型和广义矩量法用于面板，并使用单个国家的普通最小二乘法。结果验证了在毛里求斯，埃及和南非的面板层面上，创新与CO ₂排放之间呈倒U型关系。可再生能源的使用减少了面板层面的CO ₂排放。人力资本减少CO ₂小组和某些国家的排放量。此外，污染避风港假说和污染晕轮效应都得到了证实。同样，在小组一级，在9个国家中有4个国家确认了环境库兹涅茨曲线。我们的研究结果表明，应追求区域整合和将创新纳入绿色增长的所有发展阶段。
