"Moving people and things around the world by sea has a big climate impact. The
shipping industry produces almost 3% of global greenhouse gas emissions –
roughly the same as Germany – largely due to the movement of container ships,
bulk carriers and tankers.

Under international rules, these emissions are not included in any nation’s
greenhouse gas reporting. That means they often escape scrutiny.

Unlike cars, international shipping can’t shift to using low-emissions
electricity – the batteries required are too big and heavy. So clean fuels must
play a role.

A proposed shake-up of the global shipping industry would encourage the use of
clean fuels and penalise shipping companies that stick to cheaper, more
polluting fuels. Should it proceed, emissions from global shipping would be
regulated for the first time.

Using our peer-reviewed modelling, we investigated how the changes might affect
Australia’s largest export: iron ore."
