Globally, commercial ships emit almost half as much particulate matter pollutants into the air as the total amount released by the world's cars, according to a new study led by NOAA and the University of Colorado at Boulder. Ship pollutants affect local air quality and the health of people living along coastlines.
The study is the first to provide a global estimate of maritime shipping's total contribution to air particle pollution based on direct measurements of emissions. The authors estimate that globally, ships emit 0.9 teragrams, or about 2.2 million pounds, of particle pollution each year.
"Since more than 70 percent of shipping traffic takes place within 250 miles of the coastline, this is a significant health concern for coastal communities," said study lead-author Daniel Lack, a researcher with the NOAA-supported CU Cooperative Institute for Research in Environmental Sciences, based at NOAA's Earth System Research Laboratory.
