How Alternative Proteins Promote Environmental Sustainability
Could Alternative Proteins solve the climate crisis? The livestock sector is responsible for 12-20% of all greenhouse gas emissions, with meat making up 60% of the food system’s emissions — twice as much as plant-based foods. This urgency necessitates a change, and Alternative Proteins provide a viable solution. Do you want to be part of this change? Read on to find out how.
What Is the Most Sustainable Form of Protein?
Sustainability in protein production involves assessing the environmental impacts across various dimensions, including greenhouse gas emissions, land use, and water consumption. Alternative Proteins, including plant-based, cultivated, and fermentation-derived options, offer substantial environmental benefits. These proteins, derived from diverse sources such as soy, peas, lentils, and fermentation-based or cultivated methods, consistently show significantly lower carbon footprints than traditional animal-based proteins, making them a crucial part of the solution to environmental challenges.
For instance, producing one kilogram of beef generates approximately 60 kilograms of CO2-equivalent emissions, whereas the same amount of protein from legumes produces less than 10 kilograms of CO2-equivalent emissions, reducing emissions by over 80%. Additionally, plant-based proteins require less water and land, making them a more efficient and environmentally friendly choice.
What Are 4 Alternative Proteins
1. Plant-Based Proteins: These proteins are derived from soy, peas, lentils, and chickpeas. Examples include tofu, tempeh, and products from companies like Beyond Meat and Impossible Foods, which create meat analogs using plant ingredients.
2. Cultivated Meat: Also known as lab-grown or cell-based meat, these alternatives involve growing animal cells in a controlled environment to produce meat without raising and slaughtering animals. Companies like Eat Just and Memphis Meats are pioneers in this field.

3. Fermentation-Derived Proteins: This category includes proteins produced through fermentation processes, such as mycoprotein from fungi (used in Quorn products) and proteins from algae and other microorganisms. Precision fermentation, where microbes are engineered to produce specific proteins, is also gaining traction, such as Perfect Day's animal-free dairy proteins.
4. Insect Protein: Edible insects like crickets and mealworms offer a high-protein, low-impact alternative. Insects require minimal land, water, and feed compared to traditional livestock, and their farming emits fewer greenhouse gases.
However, while insect proteins can be farmed with minimal environmental impact, they do not contribute to animal welfare as the other sources. The Alternative Protein industry we support focuses on providing sustainable and ethical protein sources that do not involve the use of any animals, whether vertebrate or invertebrate. Our goal is to create a food system that is entirely animal-friendly, promoting the well-being of all living creatures.
What Are the Advantages of Alternative Proteins?
Environmental Benefits
Reduced Greenhouse Gas Emissions: Livestock farming is a major contributor to greenhouse gas emissions. Alternative Protein products produce far fewer emissions, with plant-based meat substitutes having on average 50% lower environmental impact.
Water Conservation: Producing animal proteins is water-intensive. Plant-based meat can reduce water use by up to 99 percent and cultivated meat by 66 percent (compared to conventional beef).
Land Preservation: Livestock farming requires large amounts of arable land. Alternative Proteins can be produced using less land, allowing for the preservation of natural habitats and biodiversity.
Health Benefits
Nutritional Value: Alternative Proteins can offer similar or superior nutritional profiles compared to animal proteins. They can be enriched with vitamins and minerals and tailored to specific dietary needs.
Reduced Health Risks: Overconsumption of red and processed meats is linked to health issues such as heart disease and cancer. Alternative Proteins provide a healthier option without these risks.
Ethical Benefits
Animal Welfare: With Alternative Proteins representing tasty and nutritious products that are produced without animals, the need for animal farming is eliminated, addressing ethical concerns related to animal welfare.
Food Security: Rising global population necessitates urgent changes in the way we produce and distribute food. Alternative Proteins offer a sustainable solution to meet the increasing food demand without overexploiting resources.
Are Plant-Based Proteins Sustainable?
Yes, plant-based proteins are highly sustainable. They offer a significant reduction in environmental impacts compared to animal-based proteins. According to research, transitioning to a plant-based diet can reduce greenhouse gas emissions, water use, and land use significantly. Additionally, plant-based diets can enhance food security by providing sufficient nutrition while using fewer resources.
