The facts are in, and reducing food waste is the top priority listed on Project Drawdown for mitigating climate change. But as consumers, we don't always get to see how food waste plays into the larger picture of climate change. We're here to break it down for you:

Our human population is rapidly expanding - and across the globe, we're struggling to keep up. Global food production must increase by 60% by 2050 in order to meet the demands of our growing humanity.

We already use half of our world's habitable land for farming so before we even think about converting more area to farmland, let’s take a minute to consider the absurd: 30% of global food produced goes to waste (that’s 40% in the United States) each year. That's the equivalent of six garbage trucks full of edible food - gone every second. 

50% of habitable land is used for agriculture

Maybe you’ve experienced that at home but think, businesses like supermarkets and larger food processors MUST be responsible for recycling food waste, right?

Wrong! In cities, less than 2 percent of the nutrients in food by-products are recovered and put to better useAcross the board, 95% of food waste goes straight to the landfill. You read that right, 95 percent! 😧

And we’re paying the price -- although it might not be so visible in your day to day. According to the FAO, the global cost of food waste is $2.6 trillion per year (!), which includes $700 billion in environmental costs and $900 billion in social costs.

Are you shocked that the environmental cost of food waste so big? Think about everything that goes into our food before it reaches your plate: including agricultural inputs (fertilizers, water), machinery, labor, livestock, soils, as well as processing (energy), transportation, food prep, and then, finally, disposal. Half of our world’s habitable land is used for agriculture -- and land clearing is a major threat to biodiversity worldwide.

Therein lies the issue: when we waste food, we waste the resources that touch every part of that process. 

We’ll give it to you straight: 

  • The food we waste consumes more than 25% of total freshwater use and 4% of petroleum oil consumption (Our World In Data).
  • Growing food that ultimately goes to waste uses up to 19% of our fertilizer, 18% of our cropland, and 21% of our landfill volume (NRDC).

food waste's environmental impact

  • Decomposing food waste produces methane - a potent greenhouse gas with 28-36 times the global warming potential of carbon dioxide (IPCC).
  • The climate crisis is making people sicker – worsening illnesses ranging from seasonal allergies to heart and lung disease (The Guardian).
  • If food waste were a country, it would be the third-largest greenhouse gas emitter in the world -- behind the United States and China (FAO).

For all of these reasons, reducing food waste is the top priority listed on Project Drawdown for mitigating climate change TODAY. 

According to the NRDC, if we reduce food waste by 15%, we could feed more than 25 million Americans every year.
