GLOBAL CLIMATE CHANGE

• Air travel is responsible for between 4 and 9 percent of global anthropogenic climate change.

TYPES OF EMISSIONS

• Aircraft produce several types of emissions. These include Carbon Dioxide (CO2), Oxides of Nitrogen (NOx), Water Vapor (H2O), and other miscellaneous gases and elements harmful to the environment.

GROWTH

• Air travel has grown an average of 5.2% each year since 1992. This means more “air-traffic” and therefore more harmful gases and chemicals released into the atmosphere.

TRAFFIC GROWTH

• A recent study done in the UK shows that the amount of people using airports grew by 120% between 1990 and 2004.

FREQUENT FLYER PROGRAMS

• Over 130 airlines currently have some type of “miles-flown” based frequent flyer program.

• Several studies have “contemplated” discontinuing frequent flyer programs for the benefit of ethics, anti-competitiveness, and reducing aviation’s effects on the climate.
