On 1 January 2020, the allowable sulfur content of marine fuels, as capped under Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL), fell from 3.5 percent by weight to 0.5 percent by weight.

The paper also considers what further air quality improvements might be observed once New Zealand accedes to Annex VI.Show less…
