Speed limits on cargo ships could reduce their pollutants by more than half




Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth’s climate and human health, scientists have found. Their evaluation of the impact of vessel speed reduction policies, such as those proposed by the California Air Resources board, appears in ACS’ journal Environmental Science & Technology.
