Many see Iceland as a country rich in wilderness and with little pollution (like what you see in the picture from Snæfellsjökull above). But Icelanders score high on CO2 emissions. In recent years, the increase is mainly due to all the air traffic stemming from tourism.
Iceland is a top polluter, but both Luxembourg and Denmark also have high per capita emissions. Luxembourg has the world’s largest cargo aircraft carrier, Cargolux. Denmark has the world’s largest shipping company. Tourism is Iceland’s largest industry.
