Any noticeable increase in ambient temperature resulting from climatic change will have a substantial
effect on the current and developing food cold-chain. A rise in temperature will increase the risk of food
poisoning and food spoilage unless the cold-chain is extended and improved. The little data that is available
suggests that currently the cold-chain accounts for approximately 1% of CO2 production in the world,
however this is likely to increase if global temperatures increase significantly. Using the most energy efficient
refrigeration technologies it would be possible to substantially extend and improve the cold-chain
without any increase in CO2, and possibly even a decrease.
