The following table provides an overview of the
data presented for each category of product.
(1) The information for the Power Cable category includes combined
data for the Telecom and Energy operating units at the Jakarta
factories, and for the Telecom, Energy and Accessories operating
units at the Oulu factory, since these factories do not accumulate
separate details for each unit (available information relates to each
factory as a whole). The quantities produced in relation to such
information have been normalised, so the telecom cables produced
by the above operating units are identified in weight terms (rather
than in km, as in the "telecom cables" category).
(2) Hazardous and non-hazardous waste: the information for the Power
Cables category includes combined data for the Telecom and Energy
operating units at the Bishopstoke factory, since this factory does
not accumulate separate details for each unit (available information
relates to the factory as a whole).
(3) Water consumption and hazardous waste: the information for the
Power Cables category includes combined data for the Accessories
and Energy operating units at the Gron factory, since this factory
does not accumulate separate details for each unit (available
information relates to the factory as a whole).
(4) The information is significant at sector level. In fact, the quantity of
ozone-depleting substances does not relate to production activities
and, accordingly, it is reported separately in total for the Energy and
Telecom sectors.
(5) For the purpose of normalising the environmental parameters, the
volume of “power cables” produced is expressed in tonnes, being the
sum of the weights of the cables produced in the years concerned
(2011 and 2012) and the related compounds produced by Prysmian,
excluding the compounds purchased in the marketplace and simply
added to the products. Although the extruded compounds are
already included in the weight of the cable, the portion produced
by Prysmian (and not purchased in the marketplace) contributes to
the total values reported for the various environmental parameters
considered (consumption of energy and water, quantity of waste
disposed).
(6) For the purpose of normalising the environmental parameters,
the production in km relates to finished optical fibre, excluding
any semi-finished fibre sold as such by the "optical fibre" factories
considered in this Report.
(7) The production of “telecom cables” is expressed in km and obtained
by summing the production of cables made from optical fibre,
quantified in fibre km, and with those made from copper, quantified
in pair km. The decision to use km rather than tonnes to quantify
the total production of telecom cables was taken due to the fact
that the unit of measure expressed in length reflects the production
process (and the related impact of environmental parameters) more
closely than the unit of measure of production expressed in weight
terms. As an example, a change in production mix, with a greater
percentage of optical fibre cables and a lower percentage of copper
cables, would reduce the quantity of production expressed in weight
terms, even though output would be increased in length terms.
Accordingly, it is assumed that the production of telecom cables
increases if its quantity expressed in terms of length (km) increases,
and decreases if its length decreases. It does not increase (decrease)
if the quantity expressed in weight terms increases (decreases).
(8) Only absolute amounts are reported for Accessories, since
normalised units of production are not available for this category.
