The cleanest countries in the world also rank, not surprisingly, among the most beautiful countries in the world. Keeping any country with major cities clean is no small task, but the world's cleanest countries have figured out a balance between population and sanitation and work tirelessly to be the cleanest and most efficient countries. For some countries, like Singapore, this means enforcing strict laws to keep the streets clean. Others have a national culture that tends towards tidiness and find that cleanliness is enforced through societal pressure and expectations.

These clean countries are the places on earth with best air quality, the countries with the best outdoor spaces, and the countries with the cleanest cities. From the snow capped mountains of Canada to the sparkling waters of Costa Rica, there is no shortage of beauty to behold when visiting the most spotless countries on the planet.

This ranking of the cleanest countries in the world should get you on the right path to countries with the cleanest air, countries with the least litter, and the overall cleanest countries on the planet.
