McCown said tugs that burn distillate fuel like those that power the barges used in Trailer Bridge’s service to Puerto Rico, emit fewer greenhouse gas than self-propelled ships that burn residual oil.
Trailer Bridge said while ships only consume 2 percent of petroleum burned by internal combustion engines, they are responsible for a double-digit percentage of various greenhouse gases.
McCown noted Maersk Line recently announced plans to use distillate fuel while in and near California ports.
