Sainsbury’s first to test climate friendly refrigerated trailer

Sainsbury’s could reduce its greenhouse gas emissions by 70,000 tonnes of CO2 equivalent per year

Sainsbury’s could reduce its greenhouse gas emissions by 70,000 tonnes of CO2 equivalent per year if tests of a naturally refrigerated lorry trailer transporting chilled and frozen goods are successful.

The new trailer uses carbon dioxide as a refrigerant rather than hydrofluorocarbons (HFCs) which have a high global warming potential when they leak into the atmosphere. R404a, a commonly used HFC, has a warming potential almost 4,000 times greater than CO2.
