Frequently asked questions
What are the key facts about protein diversification?
The food system’s hidden costs are estimated at US$15 trillion a year — about 12% of global GDP in 2020. Investment in alternative proteins could create up to 83 million jobs globally by 2050. Plant-based protein offers greater emissions savings per dollar invested than decarbonisation in any other sector. Transitioning to healthier, sustainable diets could contribute 70% of the total economic benefits of food-system transformation.
What is protein diversification and why does it matter?
Protein diversification means broadening the mix of protein sources — plant-based, fermented and cultivated — alongside reducing reliance on animals. It is a key lever for cutting the food system’s hidden costs, estimated at US$15 trillion a year (about 12% of global GDP in 2020) across health, environmental and poverty impacts.
What are the economic benefits of shifting to alternative proteins?
Considerable. Investment in alternative proteins could create up to 83 million jobs globally by 2050, and plant-based protein offers greater emissions savings per dollar invested than decarbonisation in any other sector. Transitioning to healthier, sustainable diets could contribute 70% of the total economic benefits of food-system transformation.
