As I travel to new destinations, one of my top priorities is finding a place with clean air and water. With pollution levels rising globally, it’s more important than ever to choose cities that prioritize their residents’ health and well-being. In this article, we’ll explore the top 10 cleanest cities in the world, as ranked by Numbeo, a society that has been monitoring and classifying pollution indices for years.
What Makes a City Clean?
When evaluating cities, Numbeo considers several key factors, including:
- Air quality index: This measures the concentration of pollutants in the air and their potential impact on human health.
- Access to clean water: Cities with reliable access to clean water are considered healthier for residents.
- Water pollution: The presence of harmful chemicals or waste in waterways can have serious consequences for public health.
- Waste management: Effective waste management systems help prevent pollution and maintain a healthy environment.
- Public perception of cleanliness and order: This refers to the overall sense of well-being and quality of life among residents.
- Noise and light pollution during nighttime: Cities with minimal noise and light pollution can provide better rest for their citizens.
- Presence of public green spaces: Green spaces are essential for mental and physical health, as they promote a connection with nature and provide opportunities for recreation.
- Degree of dissatisfaction with living in the city due to pollution: This measures the negative impact of pollution on residents’ quality of life.
These factors are weighted differently, with voice-related pollution (air and water) receiving greater priority.
