Abstract: This study is a documented research work that determines the
emission quantities of HFCs, PFCs and SF6 in Thailand. The information included
in this study is comprised of secondary data that have been collected from
relevant government agency sources and the results of a field survey. The field
survey provides information about the production process, the production
output, and the emission factors for each specific production process,
extracted from the Revised 2006 IPCC Guidelines for National GHG Inventories,
Volume 3. The effect of the use of HFC-134a in the manufacturing and servicing
of household refrigerators and automobile air-conditionings was calculated
during 2001–2006 and the results indicated that the direct emission of HFCs
based on CO_2 and carbon equivalent was 59,280,394 and 16,300,616 MT carbon,
respectively. Similarly, the effect of the use of SF6 in the manufacture was
calculated during 2001-2006 and the results indicated that the direct emission
of SF6 based on CO2 and carbon equivalent was 29,473 and 8038 MT carbon,
respectively. The direct emission was calculated from the amount of HFCs, PFCs
and SF6 that had leaked or had purged directly into the atmosphere. It was
found that the direct emissions from manufacturing and servicing refrigerator
had increased and the different emissions depend on the amount of GHG that was
converted which was compared to the amount of equivalent CO_2.
