Comments

In 2007, SF6 emissions were estimated at 1 064 kt CO2 equivalent (CO2e) or 45 t in mass.

Just three sectors contributed to SF6 emissions in mainland France , which are by order of importance in 2007 :

  • manufacturing industry : 52% of total emissions,
  • energy conversion : 47%,
  • residential/tertiary : 1%.

These emissions have fallen since 1990 : -941 kt CO2e (or -39 t in mass), a decrease of 47% between 1990 and 2007.

The evolution observed came from :

  • in one hand, the SF6 consumption reduction in the magnesium production, as well in foundries than to the only factory of first fusion which closed-down in 2002. It is important to stress that this factory has been converted in recycling magnesium and is consuming SF6 at the same level than in 2000 since the year 2003. Since 2006, SF6 were not used anymore as the new owner used another product (NaCl).
  • in the other hand, from the variations of the electric equipment activity (a great fall of 151 kt CO2e has been observed since 1990 due to real improvements).

Emissions have slightly reduced in energy conversion between 1995 and 1998 mainly in a result of a better air-tight of the electric equipments and maintenance procedures until 2002. Improvements do not balance the increase of the fleet anymore since then.

From 1999, emissions began to fall in the tertiary sector, mainly as a result of this substance no longer being used for the production of some sports shoes.
