New Scientist (12 Oct 13, p 6) reports that the airlines have agreed to participate in an emissions trading scheme. That's a useful point of principle gained but may have no real effect. It will only be worthwhile if the airlines are given significantly LESS permits than their current emissions. (Why give them any? Beats me but that's how it is.)
Experience with the EU ETS and the shipping rules are discouraging but I suppose we have to hope.
