Liner giant AP Moller-Maersk will need significantly more container ship tonnage to comply with pending carbon reduction legislation, according to chief executive Soren Skou.

Estimates based on the carrier’s own fleet suggest that between five and 15% of additional capacity would be needed as the new rules take effect in the coming years, he said.

The additional tonnage will be needed as vessels were likely to slow down to meet the emissions goals set by the International Maritime Organization (IMO).
