The more people live in the vicinity of the emission source, the higher the damage in terms of premature death and diseases. [...] These prices are used in Chapter 2 to estimate the total health-related social costs of outdoor air pollution due to domestic heating and cooking for the EU27+UK and the individual countries. [...] 2.1 Methodology In order to determine the total health-related social costs of outdoor air pollution, we multiply the environmental prices (euro/ton emitted substance, see Paragraph 1.5 and Annex A) with the corresponding amount of total air pollution emissions for the EU27+UK as a whole and the individual countries. [...] In this context, it is also relevant in this study to compare the health-related costs of direct emissions due to heating and cooking in the residential sector with the health-related costs of all non-commercial transport activities by households. [...] Figure 11 shows that for the majority of EU27+UK countries (18 out of 28), health-related social costs due to heating in the residential sector are higher than the costs due to transport in the residential sector.
