SO2 = Sulphur dioxide; NO2 = Nitrogen dioxide

PCA’s 2008 SO 2 and NO 2 emissions were recalculated to reflect adjusted home heating oil consumption data.

Data for Gefco and for the Peugeot and Citroën brands were reported from the same percentage of sites as for direct consumption data.

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 NO 2 and SO 2 emissions since 1995, with reductions of, respectively, 49% and 98% over the period. These improvements have helped to improve air quality on Group sites.

In 2009, the Rennes and Sochaux plants eliminated the use of heavy fuel oil, which has effectively reduced SO 2 emissions to very low levels (although such emissions did increase in 2009 because the Sochaux plant used up its remaining heavy fuel stocks during the year).

NO 2 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 less than 500 tonnes a year.

VOC = Volatile organic compounds

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 2007, human activity produced 1,199 kt of released VOCs, source: CITEPA).

Thanks to PSA Peugeot Citroën’s strict abatement programmes, VOC emissions per painted vehicle have been more than halved since 1995. The goal is to lower per-vehicle releases to 3.42 kg in 2012 through the sustained 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, 91% of the Group’s VOCs in 2009 were emitted in Europe and 9% in the rest of the world.

VOC emissions from PCA and PMTC paintshops are calculated using the materials balance method, in compliance with European directive 1999/13/EC on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain activities and installations.
