How to access environmental impact of pork?
To assess how a given food product as e.g. pork may affect the environment a method called Life Cycle Assessment (LCA) is used. LCA is product-oriented to assess the resource use and environmental impact through a product's life cycle. An LCA is an assessment of the environmental effects a product or service has during its lifetime, from cradle to grave. In an LCA all the important processes during the products lifecycle is included (see Figure 7 for an illustration on pork). An LCA can for example be used for assessing how much greenhouse gas is emitted to the environment during the production of one kg pork meat.
