Critical Analysis of Emergency Plans for Critical Air Pollution Episodes: A Global Perspective

Air pollution is a critical environmental issue affecting cities across all continents, compromising public health and the quality of life for millions of people. It is driven by factors such as uncontrolled urban growth, accelerated industrialization, and increasing vehicle emissions, which together contribute to deteriorating air quality. The frequency and severity of critical air pollution episodes (CAPE) have risen, underscoring the need for emergency plans to mitigate health impacts. This article aims to analyze key emergency plans adopted globally, focusing on countries and cities considered references in addressing CAPE across the Northern, Central, and Southern Hemispheres. The findings reveal significant diversity in emergency plan approaches, shaped by each region’s legislative, technological, and socioeconomic contexts. Countries in the Northern Hemisphere employ robust strategies supported by advanced technologies and integrated policies. In the Central Hemisphere, efforts focus on adapting plans to challenging urban environments, while the Southern Hemisphere faces the ongoing challenge of implementing comprehensive policies. Developing effective emergency plans requires not only adapting successful practices but also continuous commitment to innovation, evaluation, and integration. This synthesis contributes to identifying best practices and strategies, enabling other regions to create coordinated and effective CAPE plans to mitigate health impacts associated with these events.
