Environmental Challenge Confronted:
Decrease energy consumption and emissions intensity
Reduce aircraft emissions intensity 30% from a 2005 baseline by 2020
Obtain 30% of jet fuel from alternative fuels by 2030
Increase FedEx Express vehicle fuel efficiency 30% from a 2005 baseline by 2020
Expand on-site generation and continue to procure renewable energy for facilities
Best Practice Undertaken:
As of 2014:
**Aircraft CO2 emissions intensity (CO2/ATM) total reduction of 21.4% from 2005 levels
-In 2014, saved more than 100 million gallons of jet fuel with FedEx® Fuel Sense and aircraft modernization programs
-FedEx® Fuel Sense has saved more than 334 million gallons of jet fuel since its inception in 2007
**Vehicle fuel efficiency cumulative improvement of 29.5% from 2005 levels
**Recognized as one of the top-25 solar-generating companies in the U.S.
-In 2014, solar facilities produced more than 8 million kWh of electricity
Examples of best practices:
-Contingency fuel analysis - uses statistical models to plan the amount of fuel required for air traffic delays or unexpected circumstances that may arise during a flight. Developing algorithms that better predict the amount of fuel needed to taxi based on the parking gate and departure runway
-Optimum Profile Descent -the most efficient and quietest way to land an aircraft is to descend at idle power from cruise altitude to the runway
-Wake turbulence separation standards - In some instances, shortening this separation can reduce taxi and flying time, save fuel and increase airport capacity, without compromising safety.
-Stack Departures - initiative with the FAA -During high-traffic periods, departing flights are separated vertically, rather than horizontally, to shorten flight tracks and reduce fuel use.
-Departure-queue management - reduces time waiting on the runway with engines running by delaying departure from the gate until predicted taxi time is acceptable
-Pilots consciously waiting to start their last engine during taxi out, or shutting the first one down while taxiing in rather than at the gate
-Aircraft technicians connecting ground power to aircraft quickly to reduce the usage of auxiliary aircraft power at ten times the cost
-Ramp agents keeping the parking gates clear to allow taxiing aircraft to arrive and marshal into position quickly and efficiently thus saving very expensive aircraft wait-time
-Reducing the weight on aircraft by transitioning to lighter containers and replacing pilots' paper manuals with electronic ones
-Engine wash process to improve the engine’s performance and help operate more efficiently.
-Active engagement with the Commercial Aviation Alternative Fuels Initiative (CAAFI), the American Society for Testing and Materials (ASTM) International, the Nature Conservancy, the U.S. Departments of Energy and Agriculture and other stakeholders in developing viable sustainable alternatives to petroleum- based jet fuel.
-Replace older-model aircraft with more fuel efficient aircraft
-Boeing 757F consumes 36% less fuel than the aircraft it replaced
-Boeing 767F consumes 30% less fuel than the aircraft it replaced
-Boeing 777F consumes 18% less fuel than the aircraft it replaced
