Toll calculations

Just been reading about new tolling rules giving big incentives for zero emission trucks.
"By May 2023, hauliers operating zero-emissions trucks – battery electric or hydrogen – must be given discounts of at least 50% on distance-based road tolls.

Member states could opt to levy extra CO2-based charges on fossil fuel lorries instead or implement both measures."
