Greenhouse gases (GHGs), including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), absorb radiation from the sun and trap heat in the atmosphere, effectively acting like a greenhouse or a layer of insulation for Earth. In Canada 10% of GHG emissions are from crop and livestock production, excluding emissions from the use of fossil fuels or from fertilizer production. In Prince Edward Island, this number increases to 23% of GHG emissions. Of these emissions, livestock production represents a considerable source of GHG emissions; from enteric methane, to methane from liquid manure storages, to the GHG emissions from livestock feed production (grains and forages). However, animal agriculture can have a positive impact on the environment and the climate, depending on management practices. This microcredential introduces the main sources of GHG emissions in livestock systems (enteric fermentation, forage production, and manure) and will assist learners in identifying livestock management practices to reduce GHG emissions and sequester carbon. Based on current research and best practices, learners will develop farm-specific strategies for their livestock operation that reduce GHG emissions and increase carbon sequestration.
