Many know the EU was going to charge a carbon emissions charge on any airline flying in the EU airspace - this included foreign airlines. Of course, this caused a furor in international relations and the US actually passed legislation (prior to the election) preventing US flagged air carriers from implementing this charge.
Now, the EU has agreed to "freeze" this for a year. This is an interesting development and one which I am sure is designed to bring "peace". I am just not sure what they are waiting on? What will really be different next year than this year?
