Global warming is an important issue when it comes to the airline industry. Air travel is estimated to cause 2% of worldwide CO2 emissions. This element has resulted in stricter international carbon emission regulations, for aircraft manufacturers and aircraft operators in order for them to reduce their carbon footprint. The ramification of this factor is that this airline will have to invest in low fuel consumption and alternative energy aircrafts in the near future (IPCC Working Groups I and III: Houghton, et al., 2000).
