Defining alternative proteins
Given how essential alternative proteins are to a global protein transition, the term itself needs to be universally understood, on the tip of more tongues, and at the top of more agendas.
What are alternative proteins?
Alternative proteins are proteins produced from plants or animal cells, or by way of fermentation. These innovative foods are designed to taste the same as or better than conventional animal products while costing the same or less.
Compared to conventionally produced proteins, alternative proteins require fewer inputs, such as land and water, and generate far fewer negative externalities, such as greenhouse gas emissions and pollution.
Some of these products are available to consumers today, including numerous plant-based and fermentation-derived options. Others, such as cultivated meats, remain primarily in development.

Why are alternative proteins important?
Alternative proteins offer a better way to feed the world.
Globally, meat consumption is the highest it has ever been, with global meat production projected to double by 2050. By making meat from plants and cultivating meat from cells, we can modernize meat production in ways that massively reduce the environmental impacts of our food system, feed more people with fewer resources, avoid contributing to the growing threat of antibiotic resistance, and free up land and ocean ecosystems for biodiversity restoration and recovery.

Plant-based and cultivated meat cut emissions by up to 92%. In order to meet the Paris Agreement, we must change how meat is made.

What needs to be done to advance alternative proteins?
If alternative proteins are to grow at the pace and scale needed to achieve climate and global health goals, increased investments in this game-changing field must be made across the public, private, and civil society sectors. Specifically, we must:
- Advance the science and build the talent pipeline
- Secure open-access R&D funding from global governments and a fair policy playing field that enables alt proteins to compete
- Support and catalyze the private sector to accelerate alternative protein growth
