6.4 Emissions
The MYTILINEOS Group activity sectors, especially the Metallurgy &
Mining Sector, generate carbon dioxide (CO
2
) emissions. These are dis-
tinguished into direct (Scope 1) and indirect (Scope 2) CO
2
emissions.
In 2014, direct emissions resulted primarily from the aluminium pro-
duction process (consumption of fuels and chemical processing as part
of the production process) and secondarily from electricity production
(consumption of natural gas), with indirect emissions resulting primar-
ily from the consumption of electricity.
The reduction in Scope 1 emissions by 36.7% compared to 2013, as
shown in the table below, is mainly due to the reduced electricity pro-
duction activity of the Group's Energy Sector.

• Fluorine emissions: Down 10%
• PFC emissions*: Down 3.8%
In the Metallurgy & Mining sector, specific targets have been set that help stabilise CO
2
emissions during aluminium
production. More specifically, primary-cast aluminium is obtained by alumina through electrolysis. This process
produces carbon dioxide, fluorine emissions and perfluorocarbons (PFCs)*.
ALUMINIUMOF GREECE is implementing specific continuous improvement projects aimed at reducing and stabilising
the levels of these emissions. Additionally, the €33 million of investments scheduled by the Group for the next two
years, which involve the creation of a new static furnace for alumina and the modernisation of the equipment in the
wider electrolysis area, are expected, in addition to increasing production and the number of jobs, to also help reduce
CO
2
emissions.
* Perfluorocarbons (CF
4
& C
2
F
6
) are gases that contribute significantly to global warming. To illustrate this, suffice to mention that 1 ton of CF
4
is
equivalent to 7,390 tons of CO
2
, while 1 ton of C
2
F
6
is equivalent to 12,200 tons of CO
2
. These perfluorocarbons can be reduced by controlling the
frequency and duration of the anode effect during the electrolysis process.
In the Energy Sector, a key objective is to maintain the efficiency rates achieved in the operation of the thermal power
plants of PROTERGIA, which are among the highest in Greece, making the best possible use of natural gas as their
primary fuel. To produce electricity, the Group’s thermal plants use natural gas. This is a fossil fuel that has a lower carbon
content compared to other mineral fuels, does not release SO
2
and particles, emits less NOx (mainly N0
2
) in exhaust gases
compared to the maximum allowed quantities under the applicable laws, and produces less C0
2
(by 70%) compared to
lignite-fired plants.

Overall, no high or medium
severity incidents, in terms
of environmental pollution,
occurred and no incidents were
reported involving spills of
hazardous materials to the en-
vironment by any of the other
Group companies.
6.5 Lubricant spills
During 2014, 66 incidents, involving spills in the soil of lubricants weighing
nearly 7 tons, took place, a quantity increased by 69% from the corresponding
one for 2013. These incidents were due to breakdowns in machinery caused
during the mining process in the tunnels of underground quarries, in the
Metallurgy & Mining Sector. These specific spills are an unavoidable part of
the mining process, as they are caused mainly by wear and tear of lubricant
pipes and by damages tomachinery by falling rocks.
In addressing this problem, DELPHI-DISTOMON is taking steps to ensure the
following: (1) The purchase of supplies (lubricant pipes) with the best quality
available in the market, to secure the maximum possible durability; (2) the
implementation, on an annual basis, of special-purpose seminars to raise
personnel awareness about the need to report and log such incidents, in line
with the company’s policy on the protection of the environment, as well as
regarding the use of specific techniques to contain the extent of the spills in
the soil; and (3) the availability of immediate response methods for dealing
with such incidents, collecting carefully the quantity of contaminated soil and
forwarding it to the hazardous waste area for appropriate handling.
* The increase in the number of incidents in 2014 is due
primarily to the increased awareness of personnel (ma-
chinery operators - technicians) about the need to report
such incidents, in combination with the simultaneous de-
crease in the number of unreported incidents.
