The World's Cleanest Air
Clean-Air Credentials: “Air passing through Canada and Greenland is scrubbed free of particles by rain and clouds before it reaches Iceland,” says the NOAA’s Russell Schnell, explaining that, unfortunately, what gaseous pollution was there to start with is sure to remain. What makes Iceland unique (and worthy of inclusion) is the fact that the pristine air extends well beyond the measuring station. Iceland’s power and heat are generated almost entirely from clean, renewable hydroelectric and geothermal sources.
Take a Breather: Maintain the purity of this unspoiled land by exploring by horseback rather than horsepower. Purebred Icelandic horses are direct descendants of Viking livestock and renowned for their friendly nature—just ask Hróðmar Bjarnason. He cofounded Eldhestar riding tours and, rather appropriately, is also a direct Viking descendant.
