Comments

Total copper emissions in 2006 in mainland France amounted to 171 t. These emissions are relatively stable during the 1990-2006 period.

The two main sources are road transport and other transports with respectively 52% and 32% of copper emissions in 2006.

Emissions from road transport entirely come from break wear, whereas the emissions from the other transports sector come essentially from railways and particularly from the wear and tear of trolley wires. The increase observed in those two sectors since 1990 is due to the expansion of the fleet and is respectively 23% and 15%.

Other sources which contributed to total copper emissions in 2006, albeit to a lesser extent, are :

  • manufacturing industry : 10%,
  • residential/tertiary : 4%,
  • energy conversion : 2%.
A decrease of 57% was observed in the sector of manufacturing industry since 1990 (-24 t). This is mainly due to electric furnace steel plants being fitted with dust extractors and their improvement in efficiency. The punctual increase of 50% between 2005 and 2006 is linked to electric furnace steel plants variable operating.
