Systematic review of factors influencing household food waste behaviour: Applying the theory of planned behaviour.

Globally, household food waste alone accounts for about $700 billion in environmental costs owing to the resources expended in producing discarded or uneaten food, along with social costs reaching approximately $900 billion. Reducing this waste by 25% could potentially feed 821 million chronically undernourished individuals. This systematic review examines household food waste behaviour using the Theory of Planned Behaviour (TPB).
