Evaluating Urban Air Quality Policy in Pakistan: A Transport Sector Perspective = 파키스탄의 도시 대기 질 정책 평가: 교통 부문 관점

다국어 초록 (Multilingual Abstract)

Air pollution represents one of the rising environmental and health challenge in Pakistan particularly within urban centers where transport emissions is the major source. This study assesses the efficiency of urban air quality policies in Pakistan’s transport sector over the period 2000 to 2020. Moreover, highlighting trends in greenhouse gas (GHG) emissions and enforcement practices. Using secondary datasets from national and international databases, correlation and linear regression analyses were conducted to evaluate how vehicle growth influences major air pollutants, including PM₁₀, PM₂.₅, NOₓ, SOₓ, and VOCs. The results show strong positive correlations between vehicular growth and pollutants such as NOₓ, SOₓ, and VOCs (r > 0.90), indicating persistent emissions despite policy interventions. The regression analysis shows that despite Pakistan’s air quality initiatives such as the Vehicle Emission Control Program (VECOP), Pakistan Clean Air Programme (PCAP), and National Electric Vehicle Policy (NEVP) designed to cut emissions. However, these initiatives remained less effective due to weak monitoring and implementation. South Korea is a good example of curbing emissions through modern monitoring systems, robust inter-institutional collaboration and proactive deployment of eco-friendly transport technologies. Pakistan still requires thorough implementation mechanisms, sustainable mobility initiatives and upgraded evidenced-based policy evaluation to align domestic and global environmental goals as its existing regulations have achieved only limited success in reducing emissions.
