5 countries that passed WHO’s Air Quality Test in 2024

At a time when air pollution is suffocating cities across the globe, a handful of countries have managed to keep their air clean and breathable.
So, what makes these countries different? Here’s a closer look at five of them—places where clean air isn’t just a luxury but a way of life.

If you've ever visited Australia, you've undoubtedly noticed the clear, pure air and deep blue skies. Its large open spaces and low population density assist, but it isn't the complete picture. Cities like Sydney and Melbourne have made large expenditures in environmentally friendly public transport, and Australia has stringent environmental laws that restrict industrial emissions. With significant efforts to control blaze smoke, which may be a significant source of air pollution, the nation also takes wildfires seriously.

In addition to being picture-perfect, New Zealand boasts some of the world's cleanest landscapes. The nation has traditionally placed a high priority on sustainability, which is reflected in its renewable energy regulations. The nation's exceptional air quality is a result of strict automobile emission regulations, a push for renewable energy, and sustainable farming methods. It's easy to understand why New Zealand made the cut when you consider that the sea winds that surround the nation aid in the removal of pollution.

When you imagine the Bahamas, you most likely picture pristine blue oceans and white sand beaches. You might be surprised to learn that the air there is equally pure. The Bahamas have naturally good air quality because they don't have any heavy businesses and their government aggressively preserves their coastal and marine surroundings. Another factor is the nation's dependence on tourism rather than manufacturing; in contrast to industrialised countries, there are just less sources of pollution.

Barbados has made large investments in renewable energy, particularly solar electricity, and is aggressively working to reduce its dependency on fossil fuels. Unlike many other developing nations, Barbados regulates its emissions by enforcing strict air pollution legislation. The result? A small island with beautiful beaches and some of the finest air in the world.

Estonia serves as evidence that environmental sustainability and technology innovation may coexist. This little European country has embraced green energy and tracks air pollution in real time with sophisticated AI-driven monitoring systems. More than half of the country is covered in forests, which naturally purify the air. Estonia is a leader in clean air projects thanks to its stringent pollution limits and significant investment in renewable energy.
Many other countries are struggling, while these five are enjoying their pristine air. Pollution levels in nations like Bangladesh, India, and Pakistan are often more than 15 times higher than WHO guidelines. Others are choking in poisonous air, while others are breathing easily.
