The eco guide to cargo ships

The shipping industry burns fossil fuels on a grand scale, and scarcely even tries to reduce its emissions

A seafaring adage goes: "If the winds are shifting, adjust your sails." But even with the disturbing winds of climate change, the shipping industry, with its combustion of fossil fuels (accounting for 2.4% of global emissions), remains outside binding emissions-reduction agreements.

There have been some eco efforts, but the Carbon War Room points out that ship owners feel little need to green their fleets, as those hiring the vessels pay the fuel costs. When the price of bunker fuel (the sludgiest oil left over from refining) drops, as it has, eco resolve disappears.
