Improvement Plan
§ Completeness– Try to acquire the activity data
• (2C3) Aluminium Production (PFCs, 1990)
• (2C4) SF6 Used in Aluminium Foundries (1990)
• (2E2) Fugitive Emissions
• (2F1~2F6) ODS substitutes by category (refrigeration, foam blowing, etc.)
§ Uncertainties– Most of the uncertainties are not calculated when collecting activity
data from companies or an agency
– Will review and improve the method
