Food waste and the climate crisis


Food waste is one of the biggest problems facing humanity today and urgent action is needed to tackle this huge environmental issue, locally and globally.


To find out more about the problem of food waste and what we can do about it, we tuned in to the Deliciously Ella podcast to listen an insightful conversation with Tessa Clarke, Co-Founder of Olio - the food waste app.


Tessa covers the shocking facts about food waste, how this is contributing to the escalating climate crisis, and the actions individuals and businesses can take to be part of the of the solution.


Food Waste - The Facts

  • Over ⅓ of all food produced around the world goes to waste at cost of $1 trillion!

  • An area larger than China and 25% of the world’s freshwater supply is used to grow food that is never eaten.

  • In the UK, households are responsible for 1/2 of all food waste.

  • According to research by Olio, we throw away 25 million slices of bread everyday in (not including shops, bakeries etc.), alongside 6 million potatoes and 1.4 million bananas! Throwing away one slice of bread might not feel like a lot, but when millions are doing it it adds up.

  • The average family throws away £800 worth of food each year that could have been eaten, adding up to £15 billion worth of food wasted.

  • Although some London boroughs offer a food waste collection service, which diverts our waste to anaerobic digestion (a process which generates energy to power our homes) most of the food waste we produce is still going to landfill.


Climate Change

  • Food waste needs to be a big part of the climate change conversation, and we need to take responsibility as individuals.

  • If food waste was a country it would be the 3rd largest emitter of greenhouse gases, after China and the US.

  • When food waste decomposes without access to oxygen in landfills it creates methane - a greenhouse gas 23 times more potent than CO2 and a huge contributor to climate change.
