NYC East River Ferries Going Green with Eco-Friendly Upgrades: NY Waterway is introducing new technology to all 31 vessels in its fleet that will reduce emissions of pollutants known as nitrogen oxides by 30 tons each.
As part of the project, diesel oxidation catalysts, or DOCs, will be added to all 31 NY Waterway ferries. The equipment controls emissions by helping the boats burn fuel more efficiently and emit less smoke, Goodman said. In addition, nine of the oldest boats in the fleet will be outfitted with new, more environmentally friendly engines. Currently, the state does not regulate emissions from marine vessels.
