Pork production accounts for ~10% of global livestock emissions1, which is ~1.5% of total global emissions2.

The vast majority of emissions in pork production come from feed (~50%) and manure (~40%)3. Methane emissions from the animal's stomach only contributes ~5%. This is in stark contrast with beef production, where these methane emissions make up 40-50% of the total emissions3 4.
