Time to party like it's ... 2008?

We recently released a comprehensive GHG emission inventory for global shipping, 2013 to 2015. It builds on previous research commissioned by the International Maritime Organization (IMO) that uses...The International Chamber of Shipping says that because our recent study shows that shipping emissions remain below their 2008 peak, not to worry. That's an overly rosy view of the data.

Quibbles over the perfect way to measure black carbon emissions from ships are keeping us from commonsense moves to control them

At a time when Arctic sea ice should be nearing its maximum extent, we’re seeing record-low ice cover for this time of year. It’s so hot at the pole that scientists are toying with ideas to re-freeze...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...

Heavy fuel oil is considered the most significant threat to the Arctic. So why isn’t it banned yet?

Heavy fuel oil (HFO) is the bottom of the barrel leftovers from the oil refining process. It is incredibly viscous; at room temperature, it can be the consistency of peanut butter. Few engines can...When we know that heavy fuel oil is the biggest threat to the Arctic marine environment, dangerous to human and environmental health, and already banned in the Antarctic, shouldn’t we seriously...
