More information
The impact assessment method used for calculating the deposited waste is “ecological scarcity 2006 / total deposited waste”. This method takes into account the volume required for storing the generated waste (including the radioactive waste) and the contaminants dumped into the water (river, sea and underground streams). The unit of the obtained value is “UBP”, which is the abbreviation for “Umweltbelastungspunkte” in German, “Ecopoints” in English.
The computation of the deposited waste is based on a life cycle analysis.
In the detailed graph, the deposited waste is disaggregatted under the following labels:
Nuclear → Emissions linked to the construction and decommissioning of the nuclear power plants. It also accounts for the emissions related to the
nuclear fuel chain.
-
-
Fossil electricity → It accounts for the operation and construction/decommissioning emissions of
gas and
coal power plants.
Elec. Import → The imported electricity also produces emissions. Besides the emissions take place in the country where the power plants are located, these are accounted in the Swiss balance as the electricity is consumed in Switzerland.
Cogeneration → It accounts for the operation and construction/decommissioning emissions of cogeneration systems.
Boilers → It accounts for the operation and construction/decommissioning emissions of boilers.
Other heat → Emissions linked to the construction and decommissioning of the next systems for heat production or cogeneration: heat pumps, solar thermal panels, direct electric heating systems and geothermal cogeneration systems.
Transport fuels → Emissions linked to the use of fuels in the
transport sector (combustion, production and distribution of the fuels are accounted).
