Specifically, the new requirements are focusing on fuel use onboard the vessel and emissions; In essence, vessels should comply with:

  1. Stricter limits for sulphur in fuel oil used on board.
  2. Ships over 5000 GT must be able to provide appropriate evidence of submitting fuel consumption data to the International Maritime Organization.

Overall, MARPOL Annex VI - Prevention of Air Pollution from Ships aims to report the impact of air pollution on human health and environments in and around ports, as well as more widely, on climate change and ozone layer depletion.

Maritime New Zealand comments

Make sure your ship is compliant before you depart.

Yet, the Ministry of Transport with the New Zealand public are still under discussion whether the country will agree; Despite the outcome of the discussions, New Zealand flagged ships visiting the ports of states party to Annex VI are required to comply with that state's regulations.

To ensure the effective implementation of MARPOL Annex VI follow the steps here. 

In the latest Concentrated Inspection Campaign (CIC) - September 1 to November 30 2018 - which focused on compliance with the MARPOL Annex VI, the most common deficiencies found were related to Bunkering Delivery Notes, Sulfur content compliance, Ozone depleting Substances and Incinerator Use.
