MANUFACTURING
Logistics ✦
Environmental indicators are being progressively integrated in the purchasing
process to see how improvements can be made in the supply and distribution
chain. This includes taking into account the regulatory pollutant emission levels
for vehicles on the road. Greenhouse gas emissions have been lowered by
reducing the amount of fuel used for transportation by optimizing routes, training
personnel in eco-driving, and so on. However, Renault wants to collect better
quantitative data by assembling an array of indicators for the various physical
fl ows.
Following the initial measurements of CO 2 emissions declared for 2006,
the logistics department set up a dedicated team to analyze the logistics
performance of Renault and its tier-one suppliers. Based on a questionnaire
designed to gather pertinent information, the analysis aims to identify potential
sources of progress that could be turned into action plans for tier-one and tiertwo
suppliers, such as grouping road transport.
The “EPE protocol”, a tool designed to measure the carbon balance, was used to
study and approve changes to transport resources. “Truck+ship” was replaced
by “train+ship” for transporting engines from Valladolid (Spain) to Bursa (Turkey),
or “barge+ship” for parts shipped from the Grand-Couronne site (France) to
assembly plants outside Europe.
Following initiatives to increase the density of transport resources between tierone
suppliers and Renault in 2007, the truck fi ll rate rose from 69% to 74% in
Europe, and the fi ll rate of sea containers from 59 m 3 to 62 m 3 worldwide.
At end-2007, Renault decided to appoint an environmental manager to
implement global management of the logistics function.
Energy consumption ✦
The action plan originally set in train in 2002 after the inclusion of several new
industrial plants, such as Pitesti (Romania), in the reporting scope has now been
extended. This has resulted in a 12.4% reduction in energy consumption per
vehicle between 2002 and 2007. This plan comprises two main strands:
Energy saving initiatives
These initiatives rely on rigorous, standardized management of non-production
time and on the convergence of best practices in facility design and control.
This involves:

developing new energy-saving regulation systems;
lighting and heating smaller areas selectively, depending on periods of activity,
or using speed regulation systems for processes with sharply fl uctuating
energy demand;
reducing demand for compressed air, especially during machining
operations;
searching continually for less energy-hungry products, such as lowtemperature
treatment baths and paints that are less sensitive to temperature
and humidity conditions;
developing energy recovery techniques such as recycling calories from
discharged air in paint shops;
boosting boiler output during renewal campaigns;
capturing atmospheric pollutants as close as possible to source in order to
reduce air renewal rates in buildings.
Using renewable energies
The fi rst phase is a detailed study on the timeliness of using renewable energies
(wind, solar thermal and solar photovoltaics, biomass, geothermal and fuel cells)
and their integration in the production process based on study results. The
second phase involves implementation at the most favorable sites:
the fi rst pilot applications of solar thermal energy were set up in 2007 at
the sites of Palencia and Valladolid Motores (Spain) and Cacia (Portugal).
These installations, designed to produce hot water, will make it possible to
shut down thermal power plants in summer, saving around 3,000 MWh and
avoiding some 600 tons of CO 2 every year;
the decision-making process is under way for projects using biomass and
wind power.
ENERGY CONSUMPTION BETWEEN 1998 AND 2007*
* The 2007 reporting scope includes production, logistics and engineering sites (see c hapter
8.4.2). The vehicles included in the production data are those manufactured by the industrial
sites in which Renault has a majority interest.
Greenhouse gases ✦
In 2003, aware of the impact of its activities on greenhouse gas emissions,
Renault conducted an inventory of greenhouse gas sources at all the production,
logistics and offi ce sites included in the scope of environmental reporting, and
reviewed its reporting system with the assistance of an independent organization.
Renault’s reporting system is compliant with the French EPE (Entreprises Pour
l’Environnement) standard for greenhouse gas inventories, which guarantees
the reliability of the results.
