One of the 16 environmental goals in Sweden is about reducing climate impact. The purpose of this goal is to stabilize greenhouse gases to a level that still preserves the biodiversity and ensures the food production. Production of animal products like meat, milk or eggs, contribute to a large extent to emissions of greenhouse gases. In today's society there is a lot of unnecessarily food waste of these animal products, which is a subject that we should pay more attention to. The aim of this study is to investigate how the reduction of food waste from animal products could reduce greenhouse gas emissions, by adding the need to produce so many animal products. We determine this by collecting data from different steps in the value chain. Primary producers, supermarkets and private persons were asked about how much of their food waste that comes from meat, dairy products and eggs. The aim is also to collect qualitative data about how conscious producers and consumers are about climate impact from animal products and how actively they work to reduce the food waste and how they handle the waste.   To investigate this subject, questionnaires were designed and distributed to primary producers, supermarkets and private consumers. Private consumers were also given a table to keep notes about their food waste. They estimated their food waste from animal products during four weeks. For the background information a literature search has also been done.   The results from primary producers and supermarkets shows that the food waste from meat products was the most abundant compared to dairy products and eggs. Private persons on the other hand mainly had food waste from animal products consisting of dairy products especially sour milk, yoghurt and milk. Private consumers average waste from meat was 0.36 kg/ four weeks which contributes with a climate impact of 6.5 kg , which will be 77.8 kg of year. This corresponds to a one-way trip by plane from Stockholm Arlanda to Copenhagen Kastrup. These numbers were only from 10 households in Sweden, which could mean an uncertainty of the results, showed that primary producers and supermarkets made efforts to reduce the waste. There is also an awareness about animal products and climate impact in all the three categories but the consciousness can be developed more. With increased knowledge about climate impact food waste can be reduced and the management of the food waste can be improved.
