Assessment of the Effectiveness of Air Quality Regulations and Policies in Mitigating Climate Change Impacts in Nigeria

Abstract

The integration of air quality management and climate change mitigation has emerged as a 
critical component of Nigeria’s sustainable development agenda. This study evaluates the 
effectiveness of existing air quality regulations and policies in addressing atmospheric 
pollution and climate-related challenges within the country. A mixed-methods research design 
was adopted, combining quantitative and qualitative approaches to provide a comprehensive 
assessment of regulatory performance, stakeholder perceptions, and environmental 
outcomes. Primary data were obtained through structured questionnaires administered to 
staff of the National Environmental Standards and Regulations Enforcement Agency 
(NESREA). Quantitative data were analyzed using Microsoft Excel to generate descriptive 
statistics, while qualitative responses were subjected to thematic analysis to identify 
recurring themes, patterns, and key issues influencing regulatory implementation. The 
findings reveal significant concerns regarding ambient air quality, with 46% of respondents 
rating current air quality conditions as either poor or very poor. Major constraints affecting 
the effectiveness of air quality regulations include weak enforcement mechanisms (69.8%), 
inadequate funding (61.9%), and corruption (50%). Industrial emissions (28.2%) and vehicular 
exhaust emissions (25.8%) were identified as the principal contributors to air pollution. 
Although respondents demonstrated a moderate level of awareness of existing air quality 
regulations (Mean = 3.29), the perceived effectiveness of these policies in mitigating climate 
change impacts was relatively low (Mean = 2.65). Qualitative findings further underscore 
systemic institutional challenges, including insufficient technical capacity, governance 
deficiencies, and inadequate environmental infrastructure. The study concludes that Nigeria’s 
air quality management framework is constrained by persistent structural and institutional 
barriers. Strengthening regulatory enforcement, enhancing institutional capacity, improving 
governance transparency, and increasing financial investment are imperative for achieving 
effective air quality management, climate change mitigation, and sustainable national 
development.
