It is possible to reduce the climate footprint of pork by replacing part of the pigs' traditional feed ley crops.

The purpose of this study was to estimate the climate effect from a life cycle perspective of introducing grass-clover biomass as an ingredient in diets to pigs in conventional Swedish pig production. The results show that the climate footprint of one kg of conventional pork can be reduced by around 13 percent by replacing parts of the pigs' traditional feed with grass-clover biomass.
