    Summary
    The inclusion of fate and exposure is a central issue in Life Cycle Impact Assessment (LCIA). According to the framework developed by the Society of Environmental Toxicity and Chemistry (SETAC), fate and exposure route are included through a fate coefficient which makes the link between an emission and the related increase in concentration. In the Critical surface-time 95 methodology, fate factors of air pollutants are determined empirically at a world level as the ratio of measured concentration to the total estimated emission flow. Based on a detailed study performed for seventeen pollutants, a correlation is developed to predict fate factors from the residence time. Variation of a factor 10000 arc observed for the fate coefficient. Empirical fate factors are compared to modelled fate factors and are found to have a similar order of magnitude
