Fuel efficiency and carbon footprint management

Carbon footprint management and continuous improvement of our fuel efficiency are critical to our commitment of operating in a way that’s environmentally sustainable. In an effort to maintain this commitment, United has made significant investments in a modern, fuel-efficient fleet while implementing operational and procedural changes to drive fuel conservation.

Improvements in fuel efficiency

Since 1994, we've improved our fuel efficiency by more than 34 percent. United has more than 370 aircraft with winglets that deliver 3 to 5 percent improvement in fuel efficiency. In addition, United is the first airline to fly with the new fuel efficiency Split Scimitar winglets that deliver up to a 2 percent additional reduction in carbon emissions and noise over standard winglets. See all of our fuel efficiency measures and calculations in our annual Corporate Responsibility Report

Carbon reduction

We support a global approach to addressing greenhouse gas emissions in the airline industry. Together with other airlines, engine and airframe manufacturers, fuel suppliers, airports and governments, we're working toward collective industry goals, including a 1.5 percent average annual fuel efficiency improvement through 2020, carbon-neutral growth beginning in 2020, and a 50 percent reduction in airline CO2 emissions by 2050 relative to 2005 baseline levels.

United also offers our customers the opportunity to reduce the carbon footprint associated with their air travel by purchasing carbon offsets or donating their miles toward the purchase of carbon offsets. Learn more about United’s carbon offset program

In addition, United has been involved in the Carbon Disclosure Project (CDP) since 2006 and was the first U.S. carrier to fully participate. You can view our 2013 CDP questionnaire response for additional information on United Airlines' carbon footprint and climate change strategy.
