Pig production is pointed out as a major contributor to main environmental issues, either at a global (global warming, energy used) or a local level (eutrophication, acidification...). Many studies have been conducted in recent years in order to quantify the effects of farming practices on the environmental impact of pig production. Amount and composition of pig manure are highly dependent on feed composition, animals housing and manure management, which also affect gaseous emissions. More recently, methodologies, such as life cycle assessment, have been developed for the environmental evaluation of contrasted pig farming systems. This allows a multi-criteria evaluation of systems including climate change, eutrophication, acidification, energy use, land use... The aim of the present paper is to review the different methodologies and data available for the environmental evaluation of pig production with a special attention to the specificities of traditional systems.
