1 The water consumption is extrapolated on the basis of the average rate of 115 litre per FTE per day, resp. 40 from 2014 on.
2 Energy conversion: 1 terajoule (TJ) = 0.278 gigawatt hours (GWh).
3 The power consumption 2012 was adjusted.
4 The heating energy consumption is based on a forecast of monthly measures of the consumption of 62 buildings (with a total floor space of over 48%).
5 The fuel consumption was adjusted from private use. The km driven, energy consumption and the air emissions were adjusted accordingly.
6 Average emissions per kilometre refer to manufacturer’s indications.
7 CO2 emissions from consumption of fossil energies, without district heating and refrigerant fluid. Swisscom published a complete climate report according to ISO 14064.
8 From Mobitool (www.mobitool.ch), car traffic, national 5-200 km, direct use, load 1.25, fuel consumption 6.23 litres per 100 km (2013), 6.01 (2014).
9 According to publications “Pollutant Emissions from Road Transport, 1990 to 2035, FOEN, update 2010, annex 6, p. 91, 2010” and “Worksheet emissions factors combustion”, FOEN, 2005 (in german).
