Mushroom Life Cycle Assessment

Gentle on the Planet

Stakeholders across the food product supply chain are increasingly interested in understanding the environmental effects of food production. Mushrooms have a unique growing process unlike any other produce item and are considered “one of the most sustainably produced foods in the United States.1” Consider this:

  • They are grown in the absence of sunlight in a climate-controlled environment.1
  • One pound of production requires only 1.8 gallons of water; 1.0 kilowatt hours of energy; generates only .7 pounds of CO2 equivalent emissions.1
  • Up to 1 million pounds produced on just 1 acre.1

A 2018 study2 published in the International Journal of Life Cycle Assessment looked at the cradle-to-gate life cycle environmental impacts of mushroom production in the United States from cultivation to harvest and preparation for bulk packaging. The goal was to create a baseline estimate of energy use, global warming potential (GWP), water use and other common environmental impacts

Below is a system diagram for the life cycle assessment (LCA) for mushroom production in the United States. The LCA looked at the three distinct phases of mushroom production: 1) composting and composting operation, 2) pasteurization and conditioning to finish the compost and 3) growing and harvesting of mushrooms.

Results show that mushroom production in the U.S. has a reduced GWP (commonly known as “carbon footprint”) more than previous mushroom LCAs conducted in other countries.3,4
