Formula, assumptions, and limits

\text{CO}_2^\text{year} = \sum_j F_j \cdot C_{f,j}, \quad \text{Intensity}_\text{BP} = \frac{\text{CO}_2^\text{year} \cdot 1000}{\text{Bollard} \cdot h_\text{pull}}

Symbol	Meaning	Unit
$Bollard$	Rated bollard pull	t
$h_\text{pull}$	Hours in bollard-pull operation	h
