PFC used in LCD manufacturing process is stable in atmosphere and it's Global Warming Potential (GWP;which defines the greenhouse effectiveness) is several thousand times, or more as high as that of CO₂.

LCD manufacturers are working together to reduce PFC emission through voluntary reduction plan.

LIREC in JEITA proposed to EDIRAK (Electronic Display Industrial Research Association of Korea) and TTLA (Taiwan TFT LCD Association) to establish worldwide WLICC (World LCD Industry Cooperation Committee) at the LCD industry level in each country and since July 2001 it has officially started to reduce voluntarily PFC emissions as one of the main activities.

LCD manufacturers have established WLICC (World LCD Industry Cooperation Committee) as worldwide LCD manufacturers committee to work on environmental and safety issues in July 2001.
