The evaluation of food chain environmental impacts was conducted using an environmental accounting model developed for the Finnish food sector, and a model of a Finnish standard lunch plate, which followed nutritional recommendations and represented division of a plate into three parts; half of the plate comprising vegetables, one quarter protein and one quarter carbohydrate.The impacts on climate change were analysed over the whole food chain. Different methods of food processing were assessed: preparation of a standard lunch plate at home, public food service preparation of lunch portions and industrial processing of ready‐made food. The overall aim was to help consumers make environmentally responsible choices in consumption and identify the key areas requiring improvement in terms of climate change and the food supply chain.According to environmental accounting in the food sector, the food chain accounts for 7% of CO2 emissions, 43% of CH4 emissions, and 50% of N2O emissions produced across the entire economy. Impact contribution of the Finnish food chain in climate change was calculated to be 14%. Food represented 15‐20% of the climate change impact of daily consumption. The carbon footprint ranged from 570g to 3.5kg equivalent CO2 for a single food portion. Impact profiles of portions varied depending on raw material composition and production procedure. Producers of animal products, food consumers making their food choices, and particularly decision makers in public catering are the critical stakeholders for minimizing climate change impacts of the food chain.
