Annual surplus (positive) or deficit (negative) of attained vs target GHG intensity.
Formula
$$ B = (I_\text{target} - I_\text{attained}) \cdot \sum_j E_j $$

| $\sum_j E_j$ | Total energy used | MJ | fuel mass × LCV |
Derived - VLSFO-equivalent deficit
$$ t_\text{VLSFO-eq} = \frac{|B|}{L_\text{VLSFO} \cdot I_\text{target}} $$
