The Impact of Lightweight In-Flight Service Carts

In pursuing a lighter ecological footprint, ANA has implemented various measures, including reducing weight in in-flight service trolleys. In 2015, ANA gradually introduced lightweight trolleys on international flights, transforming materials and streamlining design.


By May 2022, all in-flight service trolleys, including those on domestic flights, are set to be replaced.

The impact is remarkable. These new carts, featuring about 70 units per Boeing 777-300ER aircraft, have led to a substantial weight reduction of up to 10 kg per trolley. This translates to a total weight reduction of approximately 580 kg per aircraft, contributing to an annual fuel consumption reduction of about 5,700 tons across the ANA fleet. This equates to a reduction in CO2 emissions equivalent to about 17,500 Olympic-sized swimming pools.


As we move forward, ANA Airlines continues to inspire with a dedication to developing eco-friendly products and services, collectively contributing to a cleaner and more sustainable world.
