Food Waste

Consumers are estimated to waste on average 20% of all Impossible Burgers purchased (USDA ERS, 2019; based on beef).

Food waste increases the environmental impact of the Impossible Burger by 25.0%

The Carbon Footprint of an Impossible Burger is 0.75 kg CO2e per burger. The greenhouse gas emissions of a Impossible Burger are 13.0 times lower than a beef burger.

  • 34.06 g CO2e / g protein

  • 6.22 kg CO2e / 2,000 kcal

  • 6.01 kg CO2e / kg

  • 2.73 kg CO2e / lb

  • 167.5 g protein / kg (Source: Nutrition label)

  • 2,116 kcal / kg (Source: Nutrition label)

Carbon Footprint of Gasoline: 8.89 kg CO2e / gallon

  • Based on EIA (2016)

Carbon Footprint of an Impossible Burger at Impossible Foods: 3.50 kg CO2e / kg

  • From Khan et al. (2019), which is a Cradle to Processor Gate study on the Impossible Burger. The study does not include food losses or energy used at the retail and consumer stages.

  • This study was commissioned by a consulting firm, and was independently reviewed by leading academic Life Cycle Assessment (LCA) researchers.

  • Retail and consumer stages are added in subsequent sections.

Carbon Footprint of Delivery to Retail: 0.20 kg CO2e / kg

  • Based on Poore & Nemeck (2018) meta-analysis value for chilled items.

Carbon Footprint at Retail: 0.43 kg CO2e / kg

  • 0.27 kg CO2e / kg for chilled meat based on Poore & Nemeck meta-analysis.

  • Assumes a 4% retail food loss, based on the value for beef, which results in an additional 0.16 kg CO2e / kg.

Carbon Footprint of Retail to Home: 0.88 kg CO2e / kg

Carbon Footprint of Cooking: 0.27 kg CO2e / kg

  • Cooked from 40 degrees fresh to 165 degrees internal for 4 minutes on a 1,600 g 12 inch aluminum frying pan on medium heat. Cooking time increases to 8 minutes to cook 5 or more burgers on the same pan. 

  • Heat capacity proxied with hamburger meat is 3.52 J / g*C (Engineering ToolBox, 2003)

  • Assumed fresh at 40 degrees.

  • Cooking time based on manufacturer packaging.

  • For energy use calculators and the proportion of US Household size used to determine cooking proportions, see the “Carbon Footprint of Cooking” page.

Carbon Footprint of Consumer Food Loss: 1.06 kg CO2e / kg

Carbon Footprint of Disposal: 0.07 kg CO2e / kg

Cradle to Grave Carbon Footprint: 6.58 kg CO2e / kg

Additional Assumptions:

  • Energy use from refrigeration at home is not considered. The electricity load of a refrigerator is considered separate from the foods placed inside of it, because it is assumed that every household has a refrigerator, regardless of how much food is in it. The individual load of opening the refrigerator for one item has been estimated to be around 2 g CO2e / opening (0.02 MJ / opening; Terrell, 2006), and thus does not meet the cutoff for sensitivity of carbon footprints set at 2 significant digits for kg CO2e.

Square Footprint at Processor Gate: 26.91 ft2 / kg

  • From Khan et al. (2019), which is a Cradle to Processor Gate study on the Impossible Burger. The study does not include food losses or energy used at the retail and consumer stages.

  • This study was commissioned by a consulting firm, and was independently reviewed by leading academic Life Cycle Assessment (LCA) researchers.

  • Converted from the value originally reported of 2.50 m2 / kg.

Square Footprint After Food Loss: 35.04 ft2 / kg

  • Assumes a 4% retail food loss, based on the value for beef.

  • Assumes a 20% consumer loss, based on the value for beef.

  • Total food loss of 23.2% increases the Square Footprint by 35.04%.

Water Footprint After Food Loss: 36.75 gallons / kg

  • Assumes a 4% retail food loss, based on the value for beef.

  • Assumes a 20% consumer loss, based on the value for beef.

  • Total food loss of 23.2% increases the Water
