Pollution Rankings in Taiwan

The pollution ranking for Taiwan is based on a combination of visitor perceptions and data from institutions like the World Health Organization. The Pollution Index estimates overall pollution levels by considering air and water pollution, garbage disposal, and other factors, with air pollution given the highest weight, while the Pollution Exp Scale uses an exponential function to highlight extremely polluted cities.

Taichung

#1 in Pollution (#27 worldwide)

Despite Taichung's success in maintaining low crime rates, pollution remains a significant challenge for the city in 2024. Air quality issues, particularly high levels of particulate matter, are a major concern for residents. With moderate PM2.5 and PM10 levels, Taichung faces ongoing challenges in reducing air pollution to improve public health and environmental wellness.

Taipei

#2 in Pollution (#199 worldwide)

Taipei faces moderate air quality concerns primarily influenced by urban activity and traffic emissions. While the air quality index is manageable, continued monitoring is necessary. Residents are generally satisfied but remain aware of the need for improvement, especially concerning particulate levels.
