Mumbai: Entrepreneur Bryan Johnson, known for his pioneering work in longevity and bio hacking, made headlines last year with his concerns about Mumbai’s air quality. His remarks highlighted a growing global issue—the stark disparities in air quality and the profound impact of pollution on public health. While cities like Delhi regularly grapple with hazardous air pollution, some countries have successfully maintained some of the cleanest air on the planet. By examining these nations, we can uncover the policies, practices, and natural factors that contribute to their superior air quality.
Countries With the Cleanest Air
Several nations worldwide stand out for their exceptional air quality, thanks to a blend of low population density, stringent environmental regulations, and abundant natural resources. 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 showcase how sustainable practices, coupled with rich natural landscapes, can protect and enhance environmental health.
Low Population Density and Pristine Environments
Regions with fewer people often enjoy cleaner air. For instance, parts of Canada, like British Columbia and Newfoundland, benefit from proactive environmental policies and minimal industrial activity, leading to fresh, pure air. Similarly, Australia enjoys high air quality levels due to its vast territories and relatively small population, although natural events like bush fires can occasionally cause temporary pollution spikes.
Leading Nations in Environmental Sustainability
Some countries have taken bold steps to maintain exceptional air quality through strong environmental regulations and sustainability initiatives:
– Finland consistently ranks as one of the cleanest nations, thanks to its low population density, comprehensive environmental policies, and extensive green spaces.
– Iceland benefits from its small population and reliance on geothermal energy, significantly reducing pollution levels.
– New Zealand maintains pristine air through rigorous environmental laws and its remote location, minimising external pollution sources.
– Switzerland enforces strict emission controls and promotes electric vehicles, keeping urban air pollution in check.
Renewable Energy and Electric Vehicles: Key to Cleaner Air
Countries like Sweden and Norway illustrate how renewable energy and electric vehicles play pivotal roles in preserving air quality:
– Sweden prioritises renewable energy, ensuring cities like Stockholm consistently experience low AQI levels.
– Norway leads the world in electric vehicle adoption and relies heavily on hydro power, significantly reducing urban air pollution.
– Estonia, one of Europe’s greenest nations, maintains good air quality by minimising industrial emissions and preserving its forested landscapes.
– Bhutan stands out with its carbon-negative status, thanks to extensive forest cover and limited industrial activity, making it one of the cleanest-air countries globally.
A Global Call for Clean Air
The success stories of these nations prove that clean air is attainable through a combination of renewable energy, robust environmental regulations, and sustainable urban planning. Their achievements set a global benchmark, offering hope for countries struggling with pollution.
In contrast, India faces severe air quality challenges, with 13 of the world’s 20 most polluted cities located within its borders. Fine particulate matter (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. This target has since been revised to a 40% reduction or achieving national standards (60 µg/m³) by 2025-26.
While these initiatives mark progress, addressing India’s air pollution crisis requires continuous and comprehensive efforts. Stricter emission regulations, accelerated renewable energy adoption, and heightened public awareness are essential for long-term improvement. The $1.3 billion incentive scheme to promote electric vehicles, introduced last year, exemplifies India’s commitment to cleaner air.
For individuals living in heavily polluted areas, the contrast can be overwhelming. However, small actions—advocating for clean energy, reducing personal carbon footprints, and supporting environmental policies—can contribute significantly to long-term improvements.
Bryan Johnson’s concerns about Mumbai’s air quality may have sparked debate, but they also underscore a critical global issue: the urgent need for cleaner air. It’s a challenge that transcends borders, affecting everyone, everywhere.
