Carbon chicken1/18/2024 Salmon farms can be found all over the world, but Norway, Chile and the UK are the largest producers. These countries are also the largest producers. For salmon, Norway, Chile and the United Kingdom top the list. The countries with the largest “chicken footprints” are the United States, China and Brazil. We found farmed chicken and salmon have huge environmental footprints, but the vast majority (95%) were concentrated in just 5% of the world. Global environmental footprints: where does Australia stand? This allowed us to understand where and how much environmental pressure chicken and salmon production exert on the environment to better inform food system sustainability. We combined these four pressures into a single metric and mapped its distribution across the world. Run-off or discharge into waterways is a major source of nutrient pollution, which can cause algal blooms. Nitrogen and phosphorus from animal excrement and synthetic fertilisers can pollute the surrounding environment. For fisheries, it is more complex since different types of fishing gear cause different levels of disturbance to habitats and fish are caught.įreshwater is used to irrigate crops, provide drinking water for animals, and service water for cleaning pens and cooling animals. On land, feed disturbance is more straightforward as land clearing displaces habitats and animals to grow crops. Farms can manage these emissions by choosing to use renewables, reducing energy use by being more efficient, and better managing animal waste.ĭisturbance considers the land and sea area taken up by farm infrastructure as well as the area used to produce feed. from Major sources of greenhouse gas emissions include energy used in these intensive farming operations, and methane and nitrous oxide from animal excrement. Farmed salmon can be fed legumes and grains such as soybean and wheat, as well as fishmeal and oil from herrings, anchovies and sardines.
