Proposal: environmental zone for ships
"The US and Canada have submitted a proposal to the International Maritime Organization (IMO) for the designation of an Emission Control Area (ECA) around their coastlines."
In such ECAs "stringent international emission controls would apply to ocean-going ships," writes Green Car Congress.
"ECA standards will ultimately cut sulfur in fuel by 98%, and achieve reductions of NOx by 80%, PM by 85%, and SOx by 95%, relative to current levels from ocean going vessels."
Last year, the IMOs 168 members agreed to take measures to substantially reduce ocean going vessels' emissions that are said to cause around 60,000 premature deaths per year.
