Reducing food waste could help mitigate climate change

About a tenth of overall global greenhouse-gas emissions from agriculture could be traced back to food waste by mid-century, a new study shows. A team of researchers, for the first time, provides comprehensive food loss projections for countries around the world while also calculating the associated emissions.

The researchers analysed body types and food requirements for the past and different future scenarios, accounting for demographic changes as well as food demand and availability and associated emissions. They found that while the global average food demand per person remains almost constant, in the last five decades already food availability has rapidly increased.
