To reduce both carbon dioxide (CO2) emissions and costs, Japan’s ‘largest’ airline All Nippon Airways (ANA) will replace its traditional dry ice method of in-flight food and beverage refrigeration with a product made from materials used as food additives.

Adoption of the new cooling technology is expected to help reduce CO2 emission levels by around 1,700 tonnes per year, in addition to saving the company yearly packaging costs of approximately ¥200m (£1,320).

The new refrigerant will be used in the in-flight carts for maintaining a stable temperature of food and drinks for long periods of time. In addition to the sustainable cooling, staff safety will be improved due to a lower risk of frostbite compared with the handling of dry ice.

Commenting on meeting ANA’s sustainability goals, Junko Yazawa, Senior Vice President of Customer Experience Management & Planning, ANA, said, “It will benefit the environment and reduce costs while ensuring that ANA passengers continue to enjoy quality food and beverages.”

To be fully integrated into in-flight food cooling by September 20th, the new refrigerant is part of ANA’s efforts to help achieve net zero carbon emissions by 2050.
