4 Assigned amount units
The number of assigned amount units is calculated from the most recent national inventory of greenhouse gas emissions and removals (MfE, 2005). In the 2005 submission, the emissions in 1990 were 61.5Mt CO2e. This equates to 307.6 Mt of assigned amount units over the first commitment period.
The amount of assigned amount units decreased by 0.5 Mt from the previous projection due to the effect of recalculations in the national inventory. Recalculations are improvements in data, emission factors or methodologies that are back-dated from the current inventory to 1990.
