The environmental opportunity of fermentation-derived ingredients
This analysis synthesizes peer-reviewed life cycle assessment (LCA) data across fermentation ingredient categories—biomass proteins, precision fermentation proteins, and microbial oils—and compares their environmental footprints to conventional animal-derived counterparts, highlighting their environmental benefits and policy recommendations.

Reducing the environmental footprint of our food system with fermentation-derived ingredients
Fermentation-derived food ingredients can be produced at a fraction of the climate, land, water, and pollution costs of conventional animal-derived alternatives–while matching their nutritional and functional performance. As protein consumption grows worldwide, fermentation offers an efficient, scalable route to reducing the environmental impacts of food production.
A systematic review of life cycle assessment (LCA) evidence conducted by the Good Food Institute, synthesizing findings from over 30 peer-reviewed and industry publications, confirms these advantages across three fermentation pathways: biomass fermentation, precision fermentation proteins, and microbial oils.
Environmental advantages of fermentation-derived ingredients—including lower greenhouse gas emissions, land use, and water use—prevail across a range of inputs and production methods. These benefits are real but not automatic. Investments and policy action in next-generation feedstocks, production infrastructure, and renewable energy can simultaneously lower both costs and environmental impacts.
Key findings
- Biomass fermentation ingredients have consistently lower land and water use, and fewer GHG emissions than beef and pork.
- Precision fermentation proteins offer up to 97% lower GHG emissions, up to 99% lower land use, and upwards of 96% lower water use/scarcity.
- Microbial omega-3 oils can relieve pressure on overfished marine ecosystems and offer up to 99% less GHG emissions, eutrophying water pollution, and air pollution than farmed fish oils.
- Environmental performance of fermentation-derived ingredients varies significantly depending on the electricity and feedstock sources, underscoring their importance in bioprocess design and commercial site selection.
