Dirty trade: How important are greenhouse-gas emissions from international transport? | vox – Research-based policy analysis and commentary from leading economists.

I find the conclusions obvious. But the point is not simply to go local–that desire frequently papers over the pollution, for instance, caused by local trucking, as well as the possible inefficiencies ad hoc local production can get away with, as its small scale can escape scrutiny, but for policy that rewards *long-term* and *sustainable* efficiency. That is, for policies favouring modern sails and related wind technology for ships, for instance, or dirigibles for aircraft, provided those are actually more efficient to run, and also to make. And for policies that tax irresponsible practices–you know, the ones that brought us the 20th century and now this century’s rising sea of mess. (When we tally the real costs of supposedly cheap commodity energy, the expense is profound and yet to be fully plumbed. We are still paying for that litre of fuel and will be doing so for a very long time.)
