Following many years of continuous
reductions, energy consumption at
the Sonova Stäfa site increased in
financial year 2010/11 to 9.2 MWh
per employee. The causes for the increase
can be found in the occupancy
of the newly built production
center and in additional offices
which has led to an overall increase
in total energy consumption by 60%
to 9,245 MWh. Efforts are underway
to continue the positive trend of the
last few years.

Along with the increase in energy
consumption, the specific greenhouse
gas emissions also increased last
year by 50% to 1.49 tons of CO 2 equivalents
(CO 2eq) per employee. In absolute
terms, the carbon footprint of the
Sonova Stäfa site amounts to 1,493
tons of CO 2eq. A strategy to reduce the
specific carbon footprint is currently
being defined.

The specific water consumption
per employee is currently 14.7 m 3 .
In absolute terms, the expansion
of capacities at the Stäfa site has
resulted in a comparatively low
increase in the amount of water consumed
of around 9% to 14,708 m 3 .
