How does food waste relate to sustainability?
Reducing food waste provides multifaceted gains for people, planet and prosperity.

The UN Sustainable Development Goals (SDG) aim to halve food waste by 2030.
How is food waste not sustainable?

How does food waste impact sustainability and hunger?
Wasting 1.3 billion tons of food causes huge economic losses and a lot of needless hunger, but there are climate environmental issues deeply connected to food waste, according to a report from the U.N.’s Food and Agriculture Organization.
Why is food waste a sustainability issue?
This is a big environmental cost to pay for food from which humans derive little to no use. And from a food security perspective, reducing food loss and waste is a major opportunity to close the calorie gap between where the world is now and where it needs to be to sustainably feed the planet.
What impact does food waste have?
The impact of food waste also includes the energy, fuel and water used to grow food that may not be used. When food waste is sent to landfill, it contributes to greenhouse gas emissions.
What type of waste is food waste?
According to FUSIONS, “Food waste is any food, and inedible parts of food, removed from the food supply chain to be recovered or disposed (including composted, crops ploughed in/not harvested, anaerobic digestion, bio-energy production, co-generation, incineration, disposal to sewer, landfill or discarded to sea)”.
Why food waste is a problem?
When food waste ends up in landfill, it decomposes anaerobically and releases methane emissions, a greenhouse gas that is 28 times more potent than carbon dioxide over a 100-year period and 84 times more on a 20-year scale. Worldwide, 8.2% of greenhouse gas emissions result from food waste alone.
What does sustainability mean in food?
