Entrepreneur Bryan Johnson, known for his focus on longevity and biohacking, had made headlines last year for expressing concerns about Mumbai's air quality. His remarks underscore the stark differences in air quality across the world and the significant impact pollution has on health. While cities like Delhi frequently experience hazardous air pollution levels, several countries have managed to maintain some of the cleanest air on the planet. By examining these nations, we can gain valuable insights into the policies and natural advantages that contribute to superior air quality.

Countries With The Cleanest Air

Several nations around the globe boast exceptionally high air quality levels due to a combination of factors such as sparse populations, stringent environmental regulations, and vast natural landscapes. Countries like Finland, Iceland, and New Zealand consistently rank among the best in air quality, as measured by the Air Quality Index (AQI). These nations serve as examples of how sustainable practices and an abundance of natural resources can help preserve environmental health.

Low Population Density And Pristine Environments

Regions with lower population densities often experience cleaner air. Certain provinces in Canada, such as British Columbia and Newfoundland, are noted for their pure air, thanks to proactive environmental policies and fewer industrial emissions. Similarly, Australia benefits from its vast territories and relatively small population, leading to generally high air quality levels. However, natural events like bushfires occasionally cause air pollution spikes, emphasizing the impact of climate-related incidents on air purity.

Leading Nations In Environmental Sustainability

Some countries have taken proactive steps to maintain high air quality through strict environmental regulations and sustainability initiatives:

• Finland consistently ranks among the cleanest nations, benefiting from a low population density, strong environmental policies, and abundant green spaces.
• Iceland enjoys pure air due to its small population and widespread use of geothermal energy, which significantly reduces pollution.
• New Zealand maintains clean air through strict environmental regulations and its remote location, ensuring minimal pollution.
• Switzerland enforces strict emission controls and promotes electric vehicles, keeping pollution levels low even in urban areas.

Renewable Energy And Electric Vehicles : The Key To Cleaner Air

Countries such as Sweden and Norway demonstrate how renewable energy sources and the adoption of electric vehicles contribute to maintaining excellent air quality:

• Sweden prioritizes renewable energy, ensuring even urban centers like Stockholm enjoy consistently low AQI levels.
• Norway leads in electric vehicle adoption and relies heavily on hydropower, significantly reducing air pollution.
• Estonia, one of Europe's greenest countries, maintains good air quality by minimizing industrial pollution and preserving its forested landscapes.
• Bhutan has achieved carbon negativity, thanks to its extensive forest cover and low industrial activity, making it one of the cleanest-air nations in the world.

A Global Call For Clean Air

Countries with high air quality levels demonstrate that clean air is achievable through a combination of renewable energy, stringent environmental policies, and sustainable urban planning. Their success sets a global standard for nations struggling with pollution, showing that with the right strategies, air quality can be improved.​

India faces significant challenges in air quality, with 13 of the world's 20 most polluted cities located within its borders. Fine particulate air pollution (PM2.5) reduces the average Indian's life expectancy by 5.3 years. In response, the Indian government launched the National Clean Air Programme (NCAP) in 2019, aiming to reduce particulate matter concentrations by 20-30% by 2024. The NCAP has since revised its target to a 40% reduction or achieving national standards (60 µg/m³) by 2025-26. ​

While these initiatives are steps in the right direction, continuous efforts are necessary to address the severity of air pollution in India. Implementing stricter emission regulations, promoting renewable energy adoption, and enhancing public awareness are crucial components of a comprehensive strategy to improve air quality. The approval of a $1.3 billion incentive scheme to promote electric vehicles last year is a notable example of India's commitment to reducing pollution. ​

For individuals living in highly polluted areas, the contrast can feel overwhelming. However, small steps such as advocating for cleaner energy sources, reducing personal carbon footprints, and supporting environmental policies can contribute to long-term improvements. While Bryan Johnson's concerns about Mumbai's air quality may have sparked debate, they also highlight the urgent need for cleaner air worldwide, an issue that affects us all.
