The International Maritime Organization<\/a>, a United Nations agency that regulates global shipping, is writing new rules<\/a> to curb greenhouse gas emissions from ships by 2050 as it implements other regulations that will mandate cleaner-burning fuels at sea by 2020<\/a>. <\/p>\n

As researchers<\/a> who study the shipping industry<\/a>, we have determined that the benefits of greener shipping outweigh the costs. Yet global environmental rule-making, implementation and enforcement<\/a> take a long time, creating delays that can endanger public health and the environment. <\/p>\n

Heavy fuel oil<\/h2>\n

The more than 52,000 ships<\/a> crisscrossing ocean trade routes will burn more than 2 billion barrels of heavy fuel oil<\/a>
\nthis year. Heavy fuel oil, a crude oil byproduct, contains sulfur concentrations up to 1,800 times higher than the diesel fuel burned on U.S. highways<\/a>. <\/p>\n

Ships contribute between 2 and 3 percent<\/a> of the world\u2019s total greenhouse gas emissions, studies show. Unless the world takes action to control noxious air pollutants and reduce greenhouse gases, harmful pollution will grow in tandem with global trade<\/a> in the coming decades.<\/p>\n

Atmospheric processes transform ship exhaust into toxic particles, which drift far from shipping routes. Originating along shipping routes, these pollutants endanger human health and acidify lakes and streams hundreds of miles inland.<\/p>\n

Public health hazard<\/h2>\n

As part of an international team of scholars, we researched how sulfur-related pollution from ships affects human health. Our team found that ship pollution causes about 400,000 premature deaths<\/a> from lung cancer and cardiovascular disease, and 14 million cases of childhood asthma each year.<\/p>\n

Maritime regulation requires cooperation among many, if not most, of the world\u2019s nations, using their shared authority to verify compliance upon arrival in their ports. But at sea, most shipping companies operate relatively independently of the country where they are headquartered.<\/p>\n

The International Maritime Organization sets international shipping policies through consensus agreements that specify compliance requirements and leave enforcement up to national authorities. In 2008, governments and industries agreed to adopt cleaner fuels in 2020. Since then, we estimate that ship air pollution exposure contributed to more than 1.5 million premature deaths and aggravated asthma conditions for over 100 million children.<\/p>\n

\"TheGiven the climate benefits of low-carbon shipping, we believe that the world can\u2019t wait three decades to set and enforce shipping greenhouse gas targets.<\/p>\n
