On Nov. 29, 2007, the U.S. Environmental Protection Agency proposed new emission standards for diesel engines on large ocean-going ships that would require the use of high-efficiency after-treatment technology and lower sulfur marine fuels to reduce NOx and PM emissions. The advance notice of proposed rulemaking reflects the approach set out in the U.S. Government's recent proposal to the International Maritime Organization. The advance notice of proposed rulemaking targets emissions from the largest marine diesel engines used primarily for propulsion power on ocean-going vessels, such as container ships, tankers, cruise ships and bulk carriers.
