Carbon footprint of heliciculture: A case study from an Italian experimental farm

The environmental load of supplementary feeding resulted to mainly ascribable (about 74%) to maize and field bean grain cultivation (for feed mixture). It was followed by grain transport (about 17%) and processing (about 4%) to feed mill and further transport of manufactured feed components (maize-field bean-limestone) to the snail farm (about 5%). The CF score might be reduced by 18%, including potential long term CO2 sequestration in shells. As compared to other conventional macro-livestock meat sources, snail meat showed reduced GHG emissions.
