Abstract The study investigated the developmental implications of environmental taxation in Nigeria. Specifically the study examined the relationship between environmental taxation and environmental quality in the country, its influence on cost effectiveness of Nigeria firms and its contribution to the improvement of standard of living of the citizenry. Using primary data sourced from a sample of 100 respondents with the use of questionnaire, and employing series of descriptive and inferential statistical analyses. The study found out that environmental taxation is coterminous with improved environmental quality, that environmental taxation has no significant influence on cost effectiveness of Nigerian firms and that environmental taxation has not culminated into improved standard of living in the country. Thus the study concluded that government should ensure that the structure and administration of environmental taxation in Nigeria should be void of loopholes that can permit tax evasion and avoidance and that the proceeds from environmental taxes should be channelled towards remediation of environmental degradation and infrastructural development in the country. Keywords: Environmental taxation, development, cost effectiveness, environmental quality, remediation, standard of living.
