2.2 Report Methodology
The data and information presented
in the Report have been collected us-
ing the procedures and scientific cap-
ture methods applied by each Group
subsidiary, as well as from the data-
bases kept in the respective corporate
systems. The data capture and the cal-
culation of the indicators referring to
the performance of MYTILINEOS
Group are checked and verified using
the corporate SAP system, official
documents (e.g. financial statements),
in-house calculation systems avail-
able in the respective departments of
each individual Group company (e.g.
custom Excel worksheets created and
regularly updated for this specific
task), and internationally accepted cal-
culation methods, such as those pro-
vided under the OHSAS 18001 –
ELOT 1801 Occupational Health &
Safety Management Systems and the
ISO 14001 Environmental Manage-
ment Standard. With regard to social
data, these cover the initiatives taken
by each company individually as well
as the actions carried out by
MYTILINEOS HOLDINGS S.A., which
represents the entire Group. The
present Report contains data ob-
tained from direct measurements,
while – to help comparisons – the cor-
responding data for 2010 and 2011
are also given, where available. Ad-
ditionally, the Report sections on car-
bon dioxide emissions and the per-
formance in the Health & Safety do-
main provide detailed descriptions
of the calculations used to obtain the
values for the indicators developed to
address these subjects.
The procedure to determine the sub-
ject areas (materiality) contained in the
Report and relating to the challenges
that the Group faces in connection
with Sustainable Development, was
based on the following:

Stakeholders in connection with
CSR issues, after the conclusion of
the cycle of Dialogue Forums with
Stakeholders, organised in 2012
for the third year running by
ALUMINIUM S.A. and METKA S.A.,
and for the second year running by
PROTERGIA S.A. (expectations of
participants).
The principles and values of the
Group and its core commitments in
the framework of Corporate Social
Responsibility.
The introduction and application of
the procedure to determine the
key issues pertaining to the Group’s
Environmental and Social footprint,
which, in addition to the individual
CSR Teams, also involves the Man-
agement of all our subsidiaries.
The results of the working meet-
ings of the CSR Teams of the
Group companies and the collab-
oration with the Heads of Depart-
ments in the context of the data
capture and evaluation tasks. In car-
rying out the data capture and
evaluation work regarding the in-
formation required for the Report,
the CSR Teams of the Group com-
panies used as guidance the prin-
ciples of the GRI standard, to en-
sure the maximum possible com-
pleteness, comparability, accuracy,
