Pollutant Information: Perfluorocarbons
Category: Greenhouse gases
Perfluorocarbons (PFCs) contribute to climate change due to their positive radiative forcing effect. Perfluorocarbons have a range of global warming potentials (GWP), which are much higher than that of carbon. However, the small quantities emitted mean that despite the high GWP values of the individual gases, the total contribution to GWP weighted greenhouse gas emissions in the UK is small.
Since 1990, total emissions of PFCs have declined by 83%. Historically, the largest source of PFCs has been the aluminium production sector, which accounted for 94% of emissions in 1990, and still 45% as recently as 2011. By 2013, the sector's contribution had dropped to 2%, due to the closure of the last large aluminium smelting plant in the UK in March 2012, and the continued rise in emissions from the production and use of PFCs. The largest emitting sector in 2014 is electronics, accounting for around half of total emissions.
Time series graph
|Start year||End year||Sector||Information||Impact|
|1990||2005||Aluminium Production||Decline in PFC emissions (a by-product of reactions in the process for manufacturing aluminium) through declining aluminium production and improved efficiencies in the process.||Decrease in emissions|
|1990||2000||Halocarbons Use||Increase in the use of PFC in the manufacture of semiconductors.||Decrease in emissions|
