The effects of climate change pose serious threats to sustainable development in the Economic Community of Central African States (CEMAC). In this paper, we argue that for the countries in the CEMAC region to improve their climate resilience, they must simultaneously grow their human capital and reduce their waste-based N2O emissions. Efforts are ongoing in the CEMAC region to ensure plausible adaptation and resilient measures, but the hazardous consequences of climate change keep threatening peaceful coexistence. From a utilitarian perspective, human action towards the environment will be morally right when it maximizes happiness and reduces suffering for the greatest number of people. Humans are expected to take eco-friendly actions -reafforestation, appropriate waste management and environmental education; that are beneficial for inert nature and humanity This study examines the complex relationships between human capital development, climate resilience, and N2O waste emissions in CEMAC countries and the ethical implications of these relationships. The study employs quantitative analysis of primary and secondary data sources to examine these links among CEMAC nations, using Panel data from 1974 to 2023. We propose that to increase their climate resilience, CEMAC countries should prioritise the development of human capital in addition to lowering waste N2O emissions.
