Our entire food system is experiencing unprecedented pressures to reduce greenhouse gas emissions. Cows in particular are getting a lot of bad press. And they do contribute to global anthropogenic greenhouse gas emissions! But might they also be part of the solution? If so, we'll need to tackle enteric emissions.

In this four-part series, we learn and think ‘out loud’ about viable solutions for reducing or eliminating enteric emissions from livestock, and whether & where a venture-scale opportunity might exist. We explore questions like:

• Do all of the existing solutions have the same likelihood of success (commercially and for impact)?
• What sources of funding will be required to scale up enteric methane reduction solutions?  
• The case for zooming in on biogenic interventions- approaches to modify the rumen of the animal so that it produces less methane.
• What will it take to get adoption, especially of feed additives?
