Motor vehicle emissions harm public health and the environment. The ICCT estimates that exposure to vehicle emissions in the year 2005 produced at least 242,000 global early deaths. Emissions of fine particulate matter, ozone-precursors, air toxics and other harmful pollutants also produce environmental damage in the form of crop fertility losses and near-term climate warming.

Quibbles over the perfect way to measure black carbon emissions from ships are keeping us from commonsense moves to control them
Without regulation, it’s unlikely that the international maritime shipping sector will voluntarily find ways to cut black carbon emissions, despite the climate benefit. Thus, we need to move on from quibbling about the “perfect” measurement method and start debating the opportunities to cut black carbon control emissions. But we must move quickly. Because the Arctic we’re aiming to protect can’t keep its cool much longer.
