SO2 = Sulphur dioxide; NO2 = Nitrogen dioxide

PCI’s SO2 and NO2 greenhouse gas emissions in 2007 were recalculated to reflect adjusted natural gas consumption data.

 Direct SO2 and NO2 emissions, 1995-2008 (PCA)



Comments :

The Group’s assertive commitment to replacing fuel oil by natural gas whenever possible and buying more cogenerated steam has resulted in a spectacular decline in NO2 and SO2 emissions since 1995, with reductions of, respectively, 43% and 99% over the period. These improvements have helped to improve air quality on Group sites.

 

The Rennes and Sochaux plants have begun phasing out the use of heavy fuel oil, thereby reducing SO2 emissions to very low levels.

 

NO2 emissions, which are generated primarily from the burning of natural gas, are now beginning to peak thanks to the Group’s energy management policies, and are expected to stabilise at around 500 tonnes a year.

 Paintshop VOC releases by business



VOC = Volatile organic compounds

 Paintshop VOC releases, 1995-2008 (PCA)



Comments :

In France, the Group’s automobile assembly plants account for less than 1% of total volatile organic compound (VOC) emissions produced by human activity (In 2006, human activity produced 1,336 kt of released VOCs, source: CITEPA).

 

PSA Peugeot Citroën’s VOC emissions per painted vehicle have been halved since 1995. The ultimate goal is to lower per-vehicle releases to 4.0 kg through the continued systematic implementation of the best, most cost-effective technologies.

Examples include:

• shifting to water-based paints;

 • optimising robotic painting processes and operating conditions;

• installing thermal oxidation units.

 

This same process is being applied at the Sochaux, Mulhouse and Caen mechanical component plants, where existing production facilities are being brought into compliance with European directives on VOCs and end-of-life vehicles (elimination of chromium VI). All of the European plants comply with release standards set in the European directive.

 

Geographically, 90% of the Group’s VOCs in 2008 were emitted in Europe and 10% in the rest of the world.
