"Greener Skies" Project Lowers Flight Emissions by 35%

This week, Alaska Airlines demonstrated a set of next-generation flight procedures that dramatically reduced fuel consumption and carbon emissions. Under the banner of its "Greener Skies" project, AA used satellite-based guidance technology that enabled aircraft to fly more efficient landing patterns, which are shorter and more direct. The Seattle-based airline estimates that such improved descent approaches would burn 2.1 million less gallons of fuel and cut carbon emissions by 22,000...
