The world is losing large amounts of food every day due to storage conditions and other reasons including damage, while it is hoped to develop new ways to keep food cool and reduce chemicals in it.
At the annual meeting of the Montreal Protocol, a number of countries pledged to work to regulate industrial chemicals, used in refrigeration and air-conditioning systems harmful to the ozone layer, Ammon said.
The meeting took place where ministers, government officials and experts work at the headquarters of the Food and Agriculture Organization of the United Nations in Rome.
About a third of the world's food is lost or wasted, and experts suggest improving ways to keep food cool while it is stored and transported to reduce waste.
According to the agency, poor refrigeration results in the loss of about 9 percent of perishable food in developed countries and about 23 percent in developing countries.
