Hawaiian Airlines has announced that it is one of the first airlines to receive carbon credits for reducing overall emissions. The reduction has been reported to be 22,000 metric tons over the last six years through the use of environmentally friendly engine washing technologies.
Credits are given as one per one ton of carbon dioxide removed from the atmosphere. The airline says the credits awarded were certified by a leading independent standard for measuring greenhouse gas emissions. According to the airline, 22,000 metric tons of carbon dioxide is about the same amount of pollution produced by 700 cars in one year.
