We say we need to talk about a lot of things that we don’t really need to talk about. But we do need to talk about food waste. It’s a huge issue and yet it flies under the radar, covered in flies.
So, in case you didn’t know it’s one of the biggest crises facing the world today. From mouldy strawberries in fridges to the massive mound of industrial waste on a global scale, we have a problem. And, like any bad problem, it’s escalating.
We’d normally start with a fact or stat to support such strong statements but this post is going to do that with a bucketload of stats. We’ve split them into four areas – and you can click to be transported to the waste-zone of your choice.

But first, before the gloomy figures, enjoy this bright preliminary slideshow on a key factor, which is food that gets rejected from supermarkets: AKA Wonky Veg:
🌎 The Environmental Toll
The waste of food is one of the main drivers behind climate change. Food production consumes vast amounts of land, water, and energy only to end up rotting in landfills – releasing the potent greenhouse gases that cause our planet to heat.
1. Food loss and waste is estimated to generate 8-10 per cent of annual global greenhouse gas emissions [https://unfccc.int/news/food-loss-and-waste-account-for-8-10-of-annual-global-greenhouse-gas-emissions-cost-usd-1-trillion].
2. These emissions are almost five times the total emissions generated by the aviation sector [https://capacity4dev.europa.eu/library/food-waste-index-report-2024-think-eat-save-tracking-progress-halve-global-food-waste_en].

💰 The Economic Drain
Food waste isn’t just about the planet. Wasting food represents a grave financial loss across the entire supply chain, costing people, businesses, and governments nearly a trillion dollars annually. That’s money that could be put to good use otherwise.
6. The combined toll of food loss and waste on the global economy is estimated to be upwards of $940 Billion per year [https://brasil.un.org/sites/default/files/2024-03/food_waste_index_report_2024.pdf].

🥪 The next time you munch or bite…
Remember. The facts above make it clear that food waste is causing all sorts of problems beyond unsightly mould. Looking ahead, policy changes, increased awareness and clever innovations will make an impact but the mound of waste hasn’t reached its peak yet and is steadily rising. This is just a start – we’ll make sure to update this article with the latest studies, stats, and research. Feel free to use these to reinforce your story – wherever you’re telling it.
And remember, facts alone aren’t enough to shape a convincing narrative. If you’re looking for a hand telling the world about your mission, why not say hello? We’ve supported businesses of all sizes to tell their stories.
