Aggregate compliance balances across multiple ships into a single pool-level balance.
Formula
$$ B_\text{pool} = \sum_i B_i $$
Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $B_\text{pool}$ | Pool compliance balance | MJ·gCO₂e | result |
| $B_i$ | Ship $i$’s individual balance | MJ·gCO₂e | ship-level calc |
If $B_\text{pool} < 0$, the penalty applies at the pool level, not per ship.
