At Delta, we’re committed to operating in a sustainable manner and are always looking for new ways to reduce our environmental footprint. Some of our most recent efforts include improving fuel efficiency of our aircraft and ground support equipment, reducing and recycling operational waste, evaluating alternative fuels, providing commute options for employees, and creating opportunities for customers to offset greenhouse gas emissions associated with their flights.
Aircraft emissions account for 98% of our carbon footprint. In an effort to increase transparency and help identify ways to reduce our overall environmental impact, we regularly calculate and verify our complete greenhouse gas inventory.
In 2012, we were the first major U.S. carrier to receive verification of our 2005-2011 greenhouse gas emissions under The Climate Registry. This verified emissions reports can be accessed on the TCR Member Reports site.
Compared to our 2005 baseline, we have reduced annual greenhouse gas emissions from flight and ground operations by 8.5 million metric tons – an 18.5% decrease over seven years. This 8.5 million metric ton reduction in annual carbon emissions is the equivalent of taking more than 1.5 million cars off the road for a year.
In 2012, our aircraft emissions were 868,040 metric tons lower than 2011 -- the same as eliminating the annual emissions of five Boeing 747-700s.
We achieved these reductions through fleet restructuring – replacing older, less fuel-efficient jets with more modern planes – as well as:
Impact of Fuel Savings Initiatives in 2012:
We are a proud member of the International Air Transport Association (IATA), an industry organization that established a voluntary goal of improving aircraft fuel efficiency by an average of 1.5% each year from 2009 to 2020. This means reducing the amount of fuel it takes to transport passenger and cargo by 1.5% each year every year through 2020.
Since 2009, Delta decreased its fuel usage by 2.8%, while increasing the ton-miles transported by 2.5%. This equates to a 5.1% fuel efficiency improvement over the past three years (1.7% per year), exceeding IATA’s goal of 1.5%.
We comply with all applicable federal, state and local environmental laws and continue to track and set goals for spills, notices of violations, fines and waste.
At Delta, we are committed to ensuring 2013 greenhouse gas emissions remain below 2012 levels
In 2007, we became the first airline to launch a carbon offset program. Today, we work with The Nature Conservancy to offer passengers the opportunity to voluntarily offset the carbon emissions incurred from their flight through an online calculator available when booking a flight. Delta's year-round carbon offset program allows customers to purchase and retire carbon offsets on delta.com to reduce the carbon dioxide associated with their travel. Retired offsets are tracked on Markit Environmental Registry.
The Tensas River Basin Project in the Lower Mississippi River Valley, funded in part by a $1 million donation by Delta, was the first project in the program and is part of the Conservancy's forest carbon initiative. The project allowed the reforestation of 406.3 acres, which over time is estimated to sequester a net of 74,177 metric tons of carbon dioxide. Money raised through voluntary carbon offsets purchased by passengers (which will be retired by the Conservancy on their behalf), as well as funds raised through a matching program during April in honor of Earth Month, was directed to the project. Through 2012, we added almost $275,000 to this initiative..
After achieving success at Tensas River, the project has been retired from the Voluntary Carbon Offset Program in order to provide donors the opportunity to support new carbon offset projects where financial support is needed more urgently. In 2012, we renewed our commitment to provide passengers the opportunity to offset flight emissions using a new Conservancy project designed to generate carbon offsets, the Rio Bravo Climate Action Project. The Rio Bravo Climate Action Project is a partnership between The Nature Conservancy and Programme for Belize. The 6,296 hectare Avoided Planned Deforestation project, located in north-west Belize, reduces GHG emissions through the acquisition and protection of forest lands threatened by agricultural conversion. The project achieved successful verification of 1,660,260 carbon offsets in 2011.
Additionally, in 2013, Delta enrolled a new Conservancy project into the Voluntary Carbon Offset Program, located in the Appalachian Mountains.The Clinch Valley Conservation Forestry Program protects and manages 22,000 acres of working forestlands in the rural countryside of southwestern Virginia. These forests support iconic wildlife species like black bear, provide clean water for people and globally rare aquatic species, and sustain local timber jobs and economies. On Rich Mountain Farm, one of the nation’s oldest continually operated cattle ranches, the Conservancy’s improved forest management on nearly 6,000 acres has thus far sequestered more than 150,000 metric tons of carbon dioxide.
In 2007, we launched a comprehensive in-flight recycling program to collect and divert aluminum cans, plastic beverage cups, plastic bottles, newspaper and magazines from landfills in 28 U.S. airports and one international location. Rebates from in-flight recycling are donated to the Force for Global Good Habitat for Humanity program.
In the past six years, more than seven million pounds have been collected, earning more than $500,000 in rebates -- enough to fully fund five Habitat for Humanity homes.
We have had an on-site Employee Recycling Center at our headquarters in Atlanta since 2007. The center was created to provide recycling services to those living in communities with a limited ability to recycle materials generated at home.
Rebates from the Atlanta Employee Recycling Center benefit the Delta Employee and Retiree Care Fund. Since this program launched, more than 4 million pounds of material have been recycled, raising more than $44,000 toward this fund
Aircraft Cabin Maintenance has recycled 340 tons of worn aircraft carpet since 2008 through Delta’s Aircraft Carpet Recycling Program.
Employees in the U.S. have recycled 866 tons of office paper since 2011.
