Decoupling Methane Emissions from Meat with Alternative Proteins

Methane emissions from animal agriculture are on track to increase 50% by 2050 – jeopardizing global climate goals without immediate interventions. 


Methane reductions could prevent nearly half a degree in warming by 2100. That is why 150 countries joined the Global Methane Pledge to reduce global methane emissions 30% by 2030. However, these governments are at risk of underfunding one of the most powerful solutions we have in hand to curtail methane emissions – alternative proteins.

Alternative proteins are products that aim to provide consumers with the sensory experience and nutrition of animal meat using plants, fermentation, or cellular agriculture. This growing industry is providing people with essential nutrients and other benefits like improving global food security and protecting nature. Government investment in the alternative proteins sector grew in 2022 to USD 635 million, but that is less than 7% of the estimated USD 10.1 Billion per year experts believe will be needed to scale up alternative proteins to help us keep global climate targets achievable.

To help countries advance this key mitigation strategy, this new Climate Advisers policy brief offers specific recommendations both for domestic policy measures and international collaboration to advance alternative protein innovation based on three strategies:

  1. Invest in Innovation
  2. Mainstream Alternative Proteins Within International Climate Change Processes
  3. Engage in International Cooperation to Advance The Sector
