Thus, a typical coal extraction process from the Ecoinvent database was used for modeling, similarly as was done by Gabarrell et al. (2012) and Muñoz et al. (2007). A market process from the Ecoinvent database for Chinese coal was used which consists of coal extraction and an average transport distance from the coal mine to the location of use.
