Fuel which is solely used for international shipping and international aviation is not required to comply with New Zealand government initiatives to reduce greenhouse gas emissions through the Emissions Trading Scheme.

In 2011, domestic shipping was responsible for producing .3 million tonnes of carbon dioxide equivalent transport emissions and the aviation industry in New Zealand for 1 million tonnes.

For international travel in 2011, the carbon dioxide equivalent transport emissions from fuel used by New Zealand's shipping was .8 million tonnes and for aviation 2.3 million tonnes. Emissions from fuel combusted by international aviation and seagoing vessels are reported in New Zealand’s Greenhouse Gas Inventory as memo items only as recommended in the International Panel on Climate Change (IPCC) guidelines.

The lead international organisations responsible for implementing emission reduction measures and for determining the emission reduction targets for their respective sectors are: the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). The Ministry of Transport, Maritime New Zealand, and the Civil Aviation Authority represent New Zealand at the international meetings for these organisations.
