Reduce Your Wasted Food Challenge

Vegetables and fruit, including cauliflower, tomatoes, artichokes, eggplant, asparagus, zucchini, strawberries, lemons, apples, and oranges.

Preventing wasted food is one of the biggest opportunities for everyday Minnesotans to impact climate change – period. Our uneaten and tossed groceries are an enormous contributor to climate change, accounting for a full 6% of all greenhouse gas emissions in the world.

And households are the biggest contributor to this waste. The truth is that growing all that food, just to waste it, uses many resources — from water and land to the diesel and emissions behind farm equipment and refrigerated tractor trailers.

The good news is that we, as consumers, can be a real part of the climate change solution and work towards food security for all. Small changes in our behavior can make a huge difference in preventing otherwise good food from going to waste. Eating leftovers, reducing animal protein in your diet by eating more fruits and vegetables, and planning out meals for the week are just a few simple things we can do. All it takes is a little time and planning.

How does the challenge work?

The Reduce Your Wasted Food Challenge spans 5 weeks and guides participants through how to track their food waste at home, prevent waste, and save money. Participants can use the tips and tools found on this website to help with storage, planning, shopping, and cooking.

  • Start by learning how to track the volume of food that is tossed each week.
  • At the end of each week, look at what you wasted and why and determine steps you can take to prevent that food from going to waste the next week.
  • Learn more about the tools and how to reduce wasted food.
