Carbon Footprint ® : a pilot profit center
A quarry, an emulsion plant, a coldmix
plant and a works center were
selected in 2009 by Colas Midi-Méditerranée’s
Languedoc-Roussillon pilot profit center to take part
in the Carbon Footprint ® audit. The greenhouse gas
(GHG) emissions directly or indirectly associated
with each of these activities were calculated. The
audit was carried out in four stages: definition of
working parameters, awareness-raising and training
of all employees, information collection and data
analysis and retrieval. The audit is a prelude to the
definition of action plans and a change in working
practices: “We now know that there is considerable
crossroads 57
room for improvement in a number of areas. By
reducing engine idling in trucks by 30%, for example,
we can cut our GHG emissions significantly”, underlines
Renaud Guillemain, the profit center’s QSE
manager. A thermal performance assessment of the
profit center’s buildings was also carried out in order
to determine heat loss and implement the required
corrective measures. In addition, in the near future,
the profit center is planning to fit some machines
with sensors to provide practically real-time fuel consumption
data. The plan is to extend these initiatives
to cover other sites and equipment throughout the
course of 2010.
