There are major gaps in how food waste in tourism is understood and calculated, according to researchers at the University of Eastern Finland and the University of Southern California. Food waste originating from hotels, restaurants and events is recognised and can be estimated and calculated, but as the tourism industry is becoming more and more diverse, so are the sources of its food waste. Food waste is a major issue globally, and it has also been identified as the most prominent type of hospitality waste. Annually, roughly 1.3 billion tons of food is lost or goes to waste, which is equivalent to one third or even up to one half of all food intended for human consumption. Food waste is a major environmental, social and economic issue.
