Despite globalization and environment degradation being recognized as factors of income inequality, studies on ECOWAS’s globalization, environmental sustainability and inequality are scarce and contradictory due to inappropriateness of carbon emissions and trade openness as indicators of environmental sustainability and globalization respectively. This study investigates the interrelationship among globalization, environmental sustainability, and income inequality in ECOWAS within the periods 1996-2019. The panel data set was sourced from the databank of World Bank and ICRG. The study found that globalization contributed to poor environmental sustainability in the region. It is consistent with the Pollution Haven hypothesis, which contends that globalization harms the environment, particularly in developing countries with lax environmental policies in comparison to developed countries with strict environmental policies. It was further discovered that income inequality is positively influenced by financial globalization but negatively affected by trade openness and KOF globalization index. This implies that the type of foreign direct investment coming into the region further exacerbated the disparity in income distribution. Thus, owing to the region’s inadequate capital stock and abundant labor force, multinationals' capital-intensive projects are unlikely to support many of the labor-intensive industries in terms of job creation and growth sustainability. Furthermore, income inequality is negatively influenced by poor environmental sustainability. It implies that growth inclusiveness and low level of pollutants move in the same direction with income inequality. Thus, environmental sustainability failed to curtail economic inequality. The study confirmed that globalization and environmental sustainability influenced income inequality more in the long-run than in the short-run. It is recommended that the government should enact environmental laws and regulations that abate pollution and carbon-trading activities, as well as to encourage the use of green manufacturing techniques.
