A life cycle assessment (LCA) and techno-economic assessment (TEA) modeling a large-scale cultivated meat production facility in the year 2030 show that cultivated meat could have a lower carbon footprint and reduced overall environmental impacts, and be cost-competitive with conventional meat. As cultivated meat production becomes more efficient beyond 2030 as the industry scales, further cost decreases, and environmental impact reductions are expected.
Unlike previous LCAs, which relied on academic projections of cultivated meat facilities at scale, these studies were informed by data collected from more than 15 industry partners, including five cultivated meat companies and Singapore’s Agency for Science, Technology and Research.
The LCA factors in ambitious projections of what conventional animal agriculture could achieve in environmental impact improvements by 2030, including renewable energy at farm and feed facilities, reduced ammonia emissions from increased outdoor grazing, reduced methane emissions obtained through feed additives, and zero land-use change associated with soy used in feed. The results from this comparison indicate that the environmental benefits of cultivated meat are expected to be highly robust.
A detailed summary of the LCA and TEA is available here.
- Lower carbon footprint: Cultivated meat has a lower carbon footprint than most forms of conventional meat production when conventional energy is used. The vast majority of cultivated meat’s climate impact comes from electricity use at the production facility, so just as electric cars are only as clean as the source of their electricity, cultivated meat is most sustainably produced with renewable energy. Cultivated meat outperforms all forms of conventional meat production when renewable energy is used, reducing the climate footprint of beef, pork, and chicken by 92 percent, 52 percent, and 17 percent, respectively.
- Reduced air pollution: Cultivated meat reduces air pollution up to 93 percent compared to conventional beef, 49 percent compared to pork, and 29 percent compared to chicken.
- More land available for climate mitigation & biodiversity: Cultivated meat reduces land use up to 95 percent compared to beef, 72 percent compared to pork, and 63 percent compared to chicken. With this massive decrease in land use, additional opportunities arise for carbon sequestration, production of renewable energy, and protection for biodiversity. Therefore, cultivated meat’s climate benefits are likely to be far greater than the direct climate impacts measured by the LCA.
Environmental impact comparison between cultivated meat produced with renewable energy and ambitious benchmarks for conventional meat
|Cultivated meat compared to conventional chicken||Cultivated meat compared to conventional pork||Cultivated meat compared to|
|Carbon footprint||17% reduction||52% reduction||Up to 92% reduction1|
|Land use||63% reduction||72% reduction||Up to 95% reduction1|
- Improved input efficiency: Cultivated meat is more efficient than conventional meat at converting feed into meat — 15.9 times more than beef, 5.8 times more than pork, and 3.5 times more than chicken (the most efficient meat).
- Cost-competitive: At a production cost of $2.57 per pound,2 cultivated meat can be cost-competitive with some conventional meats by 2030 and serve as an affordable ingredient for plant-based and cultivated meat blends.
- New high-paying job opportunities in both rural and urban areas: The TEA finds that a single cultivated meat production facility is expected to provide 130 to 200 high-paying jobs in rural and urban areas with other opportunities opening up elsewhere in the supply chain.
- Global health (not considered in LCA): The United Nations Environment Program states that the next pandemic will most likely be caused by animal farming, and scientists globally have argued that antibiotic resistance is a growing threat made worse by the use of antibiotics on farms. Cultivated meat reduces both of these risks to zero.
“Cultivated meat has all the same fat, muscles, and tendons as any animal… All this can be done with little or no greenhouse gas emissions, aside from the electricity you need to power the [plants] where the process is done.”
— Bill Gates, How to Avoid a Climate Disaster
- Fund open-access cultivated meat research: Public funding into cultivated meat research is far short of what is needed. Governments should fund research to address critical knowledge gaps and optimize processes to scale up and lower costs.
- Incorporate cultivated meat into climate change policies: Governments committed to achieving net-zero emissions through decarbonization of their energy sector can achieve greater emissions reductions if they incorporate cultivated meat and other alternative proteins into their explicit policy priorities.
- Provide incentives and financing for cultivated meat infrastructure projects: These efforts will create jobs and ensure equitable access to cultivated meat.
- Support agency efforts: The U.S. Department of Agriculture and the Food and Drug Administration are working together to ensure that cultivated meat will be safe and properly labeled.
This LCA and TEA were conducted by the Dutch firm CE Delft. GFI and the European organization GAIA commissioned the LCA, and GFI commissioned the TEA.
1 This varies due to comparisons with beef from dairy cattle versus cattle raised exclusively for beef.
2 This figure strictly reflects the cost of goods sold and does not include markup by the manufacturer or retailer. This is the production cost rather than the price that consumers would see. This cost reflects the lowest-cost scenario in the model, and achieving it will require concerted research efforts to improve the process and inputs in addition to securing favorable financing arrangements.
