Energy-efficient
infrastructure
tioning three electric vehicles in Lausanne, Berne and Zurich – locations where Swisscom generates
an equivalent volume of solar power thanks to its own solar energy installations.
In 2010, 101,600 (–7.6%) rail tickets for business trips and 13,000 (+4%) half-fare as well as 2,600
(+3.5%) general transport passes were issued to employees.
A separate CO 2 levy of 1.5 cents per air mile has been charged on international flights since 2007,
and the money goes towards funding internal environmental projects in the field of mobility.
In 2009 the internal cost allocation model was changed to the user-pays principle. As a result,
internal car users must now pay the actual costs incurred and have an incentive to keep these to
a minimum.
Energy efficiency target agreement
In 2010 Swisscom aimed to improve energy efficiency by 17% (compared to the reference year
2002) and limit direct CO 2 emissions to a maximum of 28,109 tonnes. Details of Swisscom’s CO 2
emissions are provided below and summarised in the table at the end of this section. By the end
of 2010 Swisscom had increased energy efficiency by 17.5% versus 2002. This is in line with the
targets agreed with the EnAW. The target is an average over the years between 2008 and 2012. In
2010 Swisscom outperformed the new efficiency target (an increase of 20% by end-2015) by 2.7%,
mainly thanks to one-off measures.
Mistral project
In 2010 Swisscom continued to pursue and implement the “Mistral” energy saving project. Mistral
is a cooling technology that uses only fresh air all year round, thereby eliminating the need for
conventional energy-intensive cooling systems with compressors and significantly enhancing
energy efficiency. Moreover, Mistral requires no harmful refrigerants.
Mistral was deployed in over 432 telephone exchanges by the end of 2010, an increase of 35%
compared to the previous year. Fifteen more mobile base stations and five Swisscom Broadcast
transmission stations were also converted to the new system in the course of the year. Fresh-air
cooling also offers a genuine alternative for cooling data centres. At the end of 2010, accumulated
savings in energy consumption versus former cooling methods amounted to 15.3 GWh. Once all
installations in the public switched telephone network have been converted, Swisscom expects
to save up to 45 million kilowatt hours of electricity per year versus conventional cooling methods.
Inergie member
Swisscom has been a member of the Inergie Association since July 2010. The aim of this association,
whose members comprise Bernische Kraftwerke (BKW), IBM, Swiss Post, the municipality of
Ittigen and Swisscom, is to develop new solutions to promote energy efficiency at the municipal
level. To date, Inergie has launched a project for e-mobility as well as a smart metering/grid project
in which Swisscom is involved.
Climate
Carbon footprint
In terms of the direct consumption of fossil fuels, Swisscom’s carbon footprint has reduced slightly
to 25,422 tonnes of CO 2 , of which vehicle fuel accounts for 49.7% and heating fuel 50.3%. Swisscom
is therefore still on track with the targets agreed with the Energy Agency for Industry (EnAW). The
electricity mix purchased in Switzerland as well as the district heating consumed by Swisscom are
not generated from fossil fuels and are therefore free from CO 2 emissions. In its reporting,
Swisscom applies the EnAW conversion factor for electricity production. While Swisscom does not
conduct an estimation of other indirect CO 2 emissions at present (Scope 3 of the Greenhouse Gas
Protocol Initiative), it continues to pursue ways of evaluating CO 2 emissions in suppliers’ logistical
processes.
