Food waste: The impact on society and environment… and what you can do against it

Can you imagine 931 million tons of food?


That's equal 23 million fully loaded 40-tonne trucks front-to-back. Enough to circle around the earth 7 times.


This is the quantity of food waste generated in 2019. More than a half of it, 568 tonnes, are produced by households, according to the UNEP Food Waste Index 2021.


On the other side of the medal, the number of people facing poverty and hunger is rising. Last year alone, up to 811 million people in the world faced malnourishment and 2,37 billion people were left without food or unable to eat a healthy, balanced diet on a regular basis.


On the September 29th, the International Day of Awareness of Food Loss and Waste calls public goverments, local municipalities, as well private business and each of us individually to action, to prioritise actions and move ahead with innovation to reduce food loss and waste towards restoring and building back better and resilient food systems.



Food waste impacts not only society, but also environment. 8-10% of global greenhouse gas emissions are related to non-consumed food. When food is lost or wasted, all the resources that were used to produce this food - including water, land, energy, labour and capital - go to waste. In addition, the disposal of food loss and waste in landfills, leads to greenhouse gas emissions, contributing to climate change.
