Improving the Energy Efficiency Of The Cold Chain

Supported by the Carbon Trust, the British Frozen Food Federation (BFFF) investigated the potential to reduce energy usage and CO2 emissions by managing operating temperatures more effectively, where appropriate, without reducing food quality or food safety.
