EU court case nudges world towards carbon tariffs

(Reuters) - The European Union took a step closer on Thursday to limiting world airline carbon emissions, which may point towards wider border measures against high-carbon industries and countries given a void in international climate action.

The EU is the first jurisdiction to try and limit carbon emissions beyond its own borders, acting to shield the competitiveness of domestic airlines from participation in its own emissions trading scheme from next year.

Such schemes force polluters to buy permits called allowances above a certain quota or emissions cap.
