Is it finally time to be bullish on IMO’s climate policy?

An economics blogger I follow once wrote that it’s impossible to be a long-run market bull if you’re always a short-term market bear. The adage, which points out that it’s philosophically...Progress in establishing a cap on GHG emissions from shipping has been slow going. But, last week, the IMO finally passed a resolution on the first global climate framework for international shipping...

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...
