Confronting Climate Change: Stop-Gap Measures to Reduce Greenhouse Gas Emissions: Speed limits on cargo ships could reduce their pollutants by more than half

Today’s report concludes that 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. That would reduce the impact of marine shipping on Earth’s climate and on human health, the scientists say. Their evaluation of the impact of vessel speed reduction policies appears in ACS’ journal Environmental Science and Technology.
