Comments

 

The level of CO emissions observed in 2006 attained 5 179 kt. After having increased sharply between 1960 and 1973 (+7 844 kt, i.e. +80%), the emissions are decreasing steadily since then (-70%, a diminution of -11 089 kt during the period 1973-2006). Those changes are 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 stabilisation of the emissions between 2003 and 2004, emissions are decreasing again (-1 004 kt, a diminution of 16% between 2004 and 2006). The decline is observed in every sector except LULUCF which stays steady.

All the sectors contribute to CO emissions. Their distribution changes according to the years. In 1960, the main sector was manufacturing industry with 37% of total emissions while road transport represented only 26% of total emissions.

In 2006, the three main sectors emitting CO were :

  • residential/tertiary (33% of total emissions in mainland France ),
  • manufacturing industry (32%),
  • road transport (24%).
