Sažetak
In recent years the impact of physical processes within an urban water system to a global climate change has gained an increasing attention. As a measure of this impact a greenhouse gas (GHG) emissions are primarily considered. Totality of all greenhouse gas contributions (without the influence of water vapour) is expressed as the CO2 equivalent. This express the potential impact on global warming of various greenhouse gases as an equivalent value of CO2 emissions. GHG emissions are taken into account as a by-product of the electricity production that is consumed in the process of water abstraction, water conditioning, water distribution and wastewater treatment. Also, GHG emissions in urban water system are sometimes associated with GHG emissions caused by the end user. The resulting emissions are considered in terms of the energy used in the mentioned processes while the emissions as a result of the process itself (for example, the formation of various gases in the purification process) are usually not taken into account. Procedures for quantifying the contributing emissions have been developed over the last years for sewerage systems and wastewater treatment processes, while the same are lacking for water supply systems. This paper deals with determining a unit value of greenhouse gas emissions in the form of CO2e for 14 water supply systems in the Republic of Croatia.
