Cutting Carbon from Ships

The war of words sparked by Europe’s requirement that airlines serving EU airports join its Emissions Trading System continues to heat up (see, for example, here and here and here and here). A group...The IMO, ICAO’s shipping sector counterpart, has made the kind of progress on regulating GHG emissions that the EU is demanding of aviation. The contrast is instructive.
