  ABSTRACT: The aviation industry is a relevant part of the sizable tourism industry. The aviation industry has been growing significantly and become a source of concern for skewing the GHGs policies. The commercial aviation industry is international by its interconnected nature, and it is regulated in an international forum of the UN, the ICAO. The ICAO is taking the climate change problem into consideration but not acting in a specific manner. These factors prompted the EU to incorporate the aviation industry to its ETS. There was a significant international dispute about the matter and currently the situation is on hold. One has to consider the wider ramifications for the global tourism industry.
