Comments

In 2008, PFC emissions represented 554 kt CO2 equivalent (CO2). Emissions dropped since 1990 as they fell by almost 87% (-3 739 kt CO2).

The manufacturing industry sector accounted for the entire PFC emissions.

The sectors contributing to PFC emissions were :

  • production of first fusion aluminium (PFC production),
  • production of trifluoroacetic or TFA (CF 4 producing PFCs),
  • production of semiconductors (use of PFCs).

After having fallen sharply, between 1990 and 1996, as a result of improvements in the aluminium electrolysis process, PFC emissions have much fluctuated these last years due to the rise in production of aluminium coupled with a non-optimum control and with the development of the semiconductor industry. In 2000 and 2001 emission control in the aluminium industry has improved, resulting in a further reduction in emissions thus residual difficulties in 2002 and 2003.

The decline observed since 2004 was a result of, in one hand, the closing down of two industries of aluminium production, one in 2003 and the other one in 2008, with however a steady production. An improvement in efficiency at another aluminium industry has allowed to reduce moreover the emissions in 2005.

Compared to HFCs, the GWP of the PFCs emitted are in a narrower fork, from 6 500 to 9 200, whereas for HFCs, it is spread out from 140 to 11 700. The evolution in mass of the emissions is thus very similar to that in equivalent CO2, more especially as the structure of the emissions in terms of chemical species does not evolve much. PFC emissions in mainland France in mass have evolved from 587 t in 1990 to 76 t in 2008, a fall of 87% approximately over this period.
