Risk factors
The power consumption
LISI mainly consumes electrical energy – 58% of all the energy
consumed – but also uses natural gas for 39%. The AUTOMOTIVE
business is the biggest energy consumer; 71% of consumption is by the
LISI AUTOMOTIVE division, ahead of the LISI AEROSPACE (28%) and LISI
MEDICAL (1%) divisions.
Electricity is used for the machines and natural gas is principally used
for the heating of buildings and for Heat Treatment. This explains
why LISI AUTOMOTIVE is at the origin of 81% of the natural gas
consumed.

Energy consumption MWh/€k production
Energy consumption is the area to which the plants have given most
attention, allowing them to reduce energy consumption by 14%
between 2010 and 2011.
Many actions have been implemented individually by the plants in
order to achieve this result, including:
– the elimination of air leaks;
– the replacement of oversized compressors by variable-flow
compressors;
– improvements in the maintenance of the equipment;
– adaptation of production tools to precise requirements (heat
treatment furnaces which are not oversized in the LISI AEROSPACE
division for example).
The tonnage of Greenhouse Gases directly resulting from energy
consumption increased by 6% between 2010 and 2011, or the
equivalent of 700 tons of CO
2
. However, in proportion to activity
levels, and all sites taken together, the production of CO
2
per €k of
production improved by 17%, confirming the improved control of
energy consumption.

Utilization of hazardous products – kg/€k production
With its customers, LISI is working on reducing the number of
hazardous products handled on the production sites.
Between 2010 and 2011, LISI thereby reduced the number of
dangerous products used by 19% and, at the same time, the ratio of
consumption to activity (€k of production) fell by 16%.
All this substitution work is being carried out over the long-term in
collaboration with our customers, who confirm the absence of any
impact on the final quality of the products manufactured.
Waste
From 2011 onwards, LISI modified one of its two waste indicators in
order to make it more consistent with its activities. The tonnage of
waste per €k of production is still monitored every year; however a
new indicator has been introduced in order tomeasure the percentage
of waste sorted. In 2011, 94% of the waste produced by the plants was
sorted. The absence of historical records prevents us fromdetermining
whether this percentage is an improvement.

Waste – kg/€k production
In 2011, 23.5 kg of waste was produced per €k of production, or 17%
less than in 2010. This is an area which has been identified as showing
room for improvement, so LISI is seeking tomake this subject one of its
objectives in the environmental domain for future years.
