Doing so enables us to both save on jet fuel costs and reduce GHG emissions. American has set a target to achieve a 50 million-gallon absolute reduction in jet fuel use by 2025, using 2019 aircraft as a baseline. That is, aircraft in our fleet as of January 2019 that continue to fly through 2025 will use 50 million gallons less fuel as a result of fuel-efficiency initiatives. We have implemented a host of fuel-savings initiatives, both on the ground and in the air, focused on three key areas: • Operating more efficiently on the ground. We have implemented a number of operational changes to reduce on-the-ground fuel use. For example, in 2021, American developed a new application to optimize how we assign gates to aircraft at Dallas-Fort Worth International Airport (DFW). This new approach to gating optimizes for taxi time, maximizes on-time arrivals, reduces ramp congestion, minimizes gate conflicts, saves fuel and reduces GHG emissions. Leveraging real-time Federal Aviation Administration (FAA) flight data and routing information, we are using the new tool for all our DFW flights today; we also expect to expand its use to other airports. Based on the reduced taxi time resulting from use of the tool today, we project full-year fuel savings of 870,000 gallons at DFW alone, equal to more than 2,600 metric tons of CO 2 . American has also reduced the use of onboard auxiliary power units during flight preparation by connecting to less carbon-intensive electric ground power at the airport terminal. We have also increased our use of single-engine AMERICAN AIRLINES ESG REPORT 2021 15 \\ Indexes & Data \\ Customers \\ Team Members \\ Safety \\ ESG Strategy CEO Message ADDRESSING CLIMATE CHANGE \\ Climate Change
