Laurel-Moffat-Southwest-Airlines.jpeg No one needs to tell Laurel Moffat, Senior Communication Specialist at Southwest Airlines, how hard it is for the airline industry to be green. Just last year, Southwest used nearly 2 billion gallons of fuel to operate its fleet. But, that same year, the company invested nearly $400 million to increase its fuel efficiency and reduce emissions. Another innovation the airline is touting is its satellite-based navigation system, which guides pilots on the most efficient routes possible.
