Using a life-cycle assessment (LCA) approach makes it possible to quantify all sources of GHG emissions from pork production in Quebec and then estimate the carbon footprint. Growing grains for pig feed, feed production, manure management, farm operations, transportation and abattoir operations were all considered in this study.
Pork producers have taken this initiative because the globalization of markets has a need for positive positioning where environmental issues are concerned. It’s also in keeping with the sustainable development indicators adopted by Quebec pork producers.
