The food industry is one of the sectors whose sales to the public sector have a great environmental impact through, for example, emissions of greenhouse gases. The types of raw materials used to produce food have a significant impact not only the total climate emissions but also on biodiversity. The foods that are available on the market differ in terms of production methods and climatic impact. This means that there is great potential for procuring authorities to choose an alternative that is more beneficial to the environment. Foods of animal origin can vary in terms of animal welfare, depending on how the specific animal husbandry is carried out. Procuring authorities can choose alternatives that involve more stringent animal protection requirements.
