Fraction of Scrapped Replaced (%)

The 'Fraction of Scrapped Replaced (%)' variable in LEAP determines what proportion of scrapped devices are immediately replaced by new sales, which then affect the stock's energy intensities and emission factors. The default setting is 100%, meaning all scrapped vehicles are replaced, and these replacements are counted separately from the primary 'sales' variable.

• The 'Fraction of Scrapped Replaced' variable defines the proportion of devices scrapped in a given year that are immediately replaced by new device sales, which are added to the stock at the same LEAP tree branch.
• Replacement sales triggered by this variable typically result in changes to emission factors, fuel economies, or energy intensities for the stock.
• The default value for this variable is 100%, and these replacement sales are calculated in addition to the figures provided in the 'sales' variable.
