Globally, food systems are responsible for approximately one-quarter of the world’s greenhouse gas (GHG) emissions, with the supply chain alone (which includes food processing, transport, packaging, and retail) contributing 18% to these emissions. The cold chain plays an important role in reducing food loss and waste (FLW), which accounts for approximately 6-8% of global emissions. However, the cold chains themselves can also significantly contribute to climate change and the depletion of the ozone layer. This is primarily due to the use of ozone-depleting substances (ODS) and greenhouse gases as refrigerants, and also emissions from the electricity necessary to operate the cold chain equipment.
