As a sustainable environmental management remains elusive in Nigeria, this paper examines the viability of using religious value as a potent strategy to combat the myriad of environmental problems that have bedeviled the country in recent years. In doing so, it investigates the environmental ethics and values as embedded in the three major religions in Nigeria -Christianity, Islamic and African Traditional religions. The study finds that those religions are entrenched with different but complimentary environmental ethics and values which can serve as paradigm upon which a viable and sustainable environmental management can be developed. It recommends, therefore that governments and all other environment stakeholders should embrace ecotheology as a potent instrument to achieving sustainable environmental management in Nigeria. I.
