Aplikace charakterizačního faktoru nedostatku vody ve studiích LCA v podmínkách České republiky - Application of the water unavailability factor for characterisation of water use in LCA studies in the Czech Republic

The following article summarises the results of testing a method for the characterisation of water use in the system of life cycle assessment in the Czech Republic. The chosen method allows for robust expression of water use in the equivalent values of the reference system. The method is based on the potential renewability of water resources. To apply the method in the Czech Republic, characterisation factor values were derived for individual hydrological third‑order catchments in the Czech Republic. These values were compared with values calculated for specific profiles from the Czech Hydrometeorological Institute. In addition, water footprint of electricity production process in selected power plants and heat plants in the Czech Republic was determined by using a tested method. Given the fact that the chosen method does not cover the issue of impacts on human health and ecosystems, the identified values represent (only) the ‘‘water scarcity footprint of electricity and heat production processes in power plants and heat plants.’
