Comments

The level of CO emissions observed in 2008 attained 4 435 kt.

In 2008, the distribution of total emissions by sector in mainland France was :

  • manufacturing industry (36%),
  • residential/tertiary (32%),
  • road transport (20%),
  • agriculture/forestry (7.5%),
  • other transports (3.0%),
  • energy conversion (1.0%).

After having increased sharply between 1960 and 1973 (+7 355 kt, i.e. +76%), the emissions are decreasing steadily since then (-74%, a diminution of -12 619 kt during the period 1973-2008). Those changes were due, in one hand, to the great variations of production of iron and steel and the diminution of the emission factor and, on the other hand, to measures implemented early 1970s to vehicles and especially cars being fitted with catalytic converters since 1993 for gasoline passenger cars and 1997 for diesel passenger cars.

After a slight increase of the emissions in 2004, emissions were decreasing again. The decline was observed in every sector except in the energy conversion, essentially in a result of variations in petroleum refining and especially the process of regeneration of catalytic cracking furnaces.
