What the data means for you

The fix starts at
your kitchen table.

We analyzed food waste across 28 countries, scored governments on their policies, and compared wealth against outcomes. The data keeps pointing to the same place: the household. That's where the problem is biggest — and where change is most possible.

~78%
of all food waste comes from households on average
1/3
of all food produced globally is lost or wasted every year
8–10%
of global greenhouse gas emissions come from food waste
What the data tells us — and what you can do

Strong laws alone don't create less waste

France has a perfect policy score of 18/18 — yet wastes nearly the same amount as the US (score: 11/18). Legislation sets the framework, but change happens at the individual level. Governments can't audit your fridge.

Your household action

Stop relying on the government to solve this

  • Plan your meals for the week before you shop — impulse buying is the #1 driver of household waste
  • Check your fridge before ordering takeout — most "expired" food is still safe to eat for days
  • Freeze leftovers the same day instead of leaving them to go bad
  • Advocate locally: push your city council to fund food education programs, not just bans

Households drive 65–95% of all food waste

Retail waste is tiny — typically just 2–10 kg per person per year. Foodservice matters more, but still trails household waste by a wide margin. The dominant variable in every country we studied is what happens inside the home.

Your household action

Treat your kitchen like the frontline

  • Do a weekly "use it up" meal — cook whatever is about to expire before restocking
  • Store food properly: most produce lasts 2–3× longer in the right part of your fridge
  • Buy whole vegetables instead of pre-cut packs — they stay fresh longer and cost less
  • Compost what you can't save — it returns nutrients to soil rather than releasing methane in landfill

Your wealth doesn't determine your waste

South Africa ($6,829 GDP/cap) produces the least waste in the dataset — 54 kg/cap. Nigeria ($2,787 GDP/cap) produces the most — 201 kg. Being richer doesn't make you wasteful, and being poorer doesn't protect you. Culture, infrastructure, and habit are the deciding factors.

Your household action

Build habits that aren't tied to your income

  • Learn what "best before" actually means — it's a quality guide, not a safety cliff
  • Use portion sizing: serve smaller amounts and go back for seconds rather than scraping plates
  • Share excess food with neighbors, food banks, or apps like Too Good To Go
  • Talk about food waste at your table — the most powerful lever is normalizing the conversation
The bottom line

Every kilogram saved is a vote for a better system.

The data is clear: governments matter, wealth is a factor, but neither is the most important variable. You are. The household is the largest contributor to food waste in every income group, every region, every country we analyzed. The most effective intervention in the world is deciding, tonight, to use what you already have.
