U.S. cracks down on ship emissions

U.S. environmental regulators on Tuesday finalized engine and fuel standards for U.S. flagged ships to cut emissions.
When fully implemented, the effort will reduce NOX emissions from ships by 80 percent, and particulate emissions by 85 percent, compared to current emissions.
Annual health benefits in 2030 should be worth between $110 billion and $270 billion, compared to compliance costs of only about $3.1 billion, the EPA said.
The EPA is also working with international organizations to control emissions from non-U.S. flagged ships.
The International Maritime Organization, a United Nations agency, is set to vote in March next year on the adoption of the joint U.S.-Canada buffer zone, which would result in stringent standards for large foreign-flagged and domestic ships operating within the designated area.
