Delta Air Lines has cut its annual greenhouse gas emissions by 8.5 million metric tons since 2005 – a reduction of 18.4 percent.
The airline recently reported successful verification of its 2012 greenhouse gas emission inventories under The Climate Registry.
Delta also improved its annual aircraft fuel efficiency by an average of 1.7 percent during the 2009 – 2012 time period. This is 1.5 percent higher than the International Air Transport Association’s fuel-efficiency goal of 1.5 percent.
Some of Delta’s initiatives to reduce carbon emissions include replacement of old 50-seat regional jets with larger, more efficient mainline aircraft, converting 35 pieces of ground support equipment from diesel to electric and implementing initiatives such as weight reduction and fuel management to reduce fuel consumption on existing aircraft.
