The manufacturers can offset the higher CO2 emissions of their 100% ICE vehicles with the lower emissions of their Hybrid and all-electric vehicles. If they continue to manufacture Mk 3 Jazzes along with the Hybrid they will lose a large portion of that offset. Particularly if the Honda e doesn't sell in huge numbers. All Honda cars will be electrified by 2022, but some won't be electrified until that date so will need the offset of those that are.
