Food Waste and the Climate Crisis

Here are some facts about food waste and its enormous impact on the climate crisis:

• 35% of our food is wasted and if our country reduced food waste by only 15%, we'd feed 25 million more people every year.¹
• 14% of all freshwater in the U.S. is used to produce our wasted food each year.²
• Every 100 pounds of food waste in our landfills sends 8.3 pounds of methane into the atmosphere.³
• Over 20 years, methane has 86 times the global warming effect of carbon dioxide.⁴
• If global food waste were a country, it would rank third in greenhouse gas emissions after China and the U.S.⁵ (Here's how food waste breaks down by type of food worldwide.)
• The contribution of food waste emissions to global warming is almost equivalent (87%) to global road transport emissions.⁵
• In North Bay Area cities, food accounts for nearly 20% of the GHG footprint in the average household.⁶
• According to a 2008 Marin Sanitary Service study, 9.4 million pounds of food waste were being disposed into Marin landfills at that time.⁷ MSS is doing great work with Marin residents and businesses to reduce that total, but there is clearly much fresh food being wasted in our county. According to a 2014 MSS study, "around 30% of the waste that goes to the landfill is food waste” in Marin.⁸

As a result, though, reducing food waste is an exciting opportunity to have collective impact on global warming:

• According to the international research coalition Project Drawdown⁹, reducing food waste is the most impactful solution to global warming.
• California state law AB 1826 requires businesses with a minimum amount of organic waste, including food and food scraps, to recycle it -- rather than having it disposed in our landfills -- as of April 1, 2016.
• California state law SB 1383 requires that at least 20% of all currently disposed edible food is recovered for human consumption by 2025.

                                      

 

 

 

 

 

 

 

 

 

 

 

It is heartbreaking to see men, women, and children go hungry in our community. And it is heartbreaking to see so much fresh, nutritious food go to waste.

Tips on Reducing Food Waste

• At work: If you have excess edible food -- prepared food, produce, dairy, eggs, meat, packaged goods, baked goods -- contact us! If you work in a food-service business, the EPA has an extensive guide to reducing wasted food and packaging here. And if you're a Marin Sanitary Service customer, check out their food-scraps-to-energy program here.

• At home: first learn the basics. Here's a good, 1-page overview and the NRDC's Dana Gunders has a great new book here.

• Then: Get clear on food dating. Wondering how long food lasts, when stored properly, past the often-confusing "use-by", "sell-by" and "best-by" dates? Here's a great overview from the USDA. The NRDC explains in this article how confusing dates on food leads to waste and provides this infographic on organizing your refrigerator to reduce waste. And here's a brief TV news piece explaining that many foods last long after the date printed on their packaging when stored properly. This brief Wall Street Journal video is also helpful.

Take a look at EatByDate.com's easy search tool here -- you can quickly look up any type of food and how long they say it will last when properly stored. (A handy infographic based on EatByDate.com's data is here.) You can also find guidelines on the shelf life of food at ShelfLifeAdvice.com.

Have extra non-perishable items at home? Consider donating them to the SF-Marin Food Bank or starting a food drive.

• At school: If you have excess edible food at your school, contact us! And here's a good infographic from the USDA on how schools can reduce food waste.

• In a faith-based organization: Check out the EPA's resources for you here. And of course, if you have excess edible food, contact us!
