WASHINGTON, Oct. 24 (UPI) -- Setting a speed limit for cargo ships sailing near ports and coastlines could cut their emission of air pollutants by up to 70 percent, a U.S. study says.
David R. Crocker III of the University of California, Riverside, and colleagues say their evaluation of the impact of vessel speed reduction policies such as those proposed by the California Air Resources board suggests they would help reduce the impact of marine shipping on Earth's climate and human health.
