ABSTRACT
Fuel subsidy removal is a controversial issue with various effects on the economy and the environment. The aim of this research is to assess the effect of the fuel subsidy removal policy on air quality using Nigeria's Federal Capital Territory (FCT) as a case study. By carrying out a geospatial assessment of the air quality in the FCT, data was gathered before and after the ratification of the fuel subsidy removal policy. The findings of this study elaborate on the relationship between air quality and the removal of fuel subsidies. Using the Sentinel-5 Precursor, this research showed that the levels of Carbon monoxide, Nitrogen dioxide, and Particulate matter (PM2.5) decreased despite the increment in fuel prices. The levels of PM2.5 showed a significant difference before and after the subsidy removal, with a high concentration of 0.332 mol/m2 before subsidy removal and a low concentration of -0.595 mol/m2 after subsidy removal. This study also brought forth suggestions to reduce the impact of fuel subsidy removal on air quality. Promoting alternative means of transportation, using cleaner energy sources, and imposing tariffs on vehicles that are no longer safe for the road are some of the suggestions provided by this research. The study offers important information about the effect that the fuel subsidy removal policy has on air quality while also offering suggestions that can help prevent further damage to the environment.
