1 The water consumption is extrapolated on the basis of the average rate of 40 litre per FTE per day
2 Energy conversion: 1 terajoule (TJ) = 0.278 gigawatt hours (GWh).
3 The heating energy consumption is based on a forecast of monthly measures of the consumption of 61 buildings (with a total floor space of over 45%).
4 The fuel consumption was adjusted from private use. The km driven, energy consumption and the air emissions were adjusted accordingly.
5 Average emissions per kilometre refer to manufacturer’s indications.
6 CO2 emissions from consumption of fossil energies, without district heating and refrigerant fluid. Swisscom published a complete climate report according to ISO 14064.
7 From Mobitool (www.mobitool.ch), car traffic, national 5-200 km, direct use, load 1.25, fuel consumption 6.01 litres per 100 km (2014), 6.00 (2015), 5.9 (2016)
8 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).
