The manufacturing processes for several advanced electronics utilise FCs for plasma-etching intricate patterns, cleaning reactor chambers and temperature control. The electronic industry in this chapter includes semiconductor, thin-film-transistor flat panel display and PV manufacturing. This chapter of the 2006 IPCC Guidelines for National Greenhouse Gas (GHG) Inventories gives guidance on the methodologies and good practices for estimating the GHG emissions from the non-energy use of the electronics industry. The electronics industry currently emits both FCs that are gases at room temperature and FCs that are liquids at room temperature. Because the carbon dioxide equivalents of each liquid differ, each should be tracked and reported separately.
