ABSTRACT
Land use as an environmental impact category is different from emissions and resource extractions. It is an activity, which encompasses several flows and physical impacts on the environment. There is a large variation in the environmental impact factor depending on latitude. Land transformation is seen as part of land use, and its impacts are allocated to and distributed over the land use temporal extension. In high latitudes the impact factor may be negative. Considering the variations between YLL from heat stress and cold moderations as a standard deviation in a normal distribution. There is a large variation in the environmental impact factor depending on latitude. In high latitudes the impact factor may be negative. Considering the variations between YLL from heat stress and cold moderations, the uncertainty is estimated to ± 1.9E-01 personyears/m2 year, as a standard deviation in a normal distribution.
