The policy dilemma of aviation emissions
GHG emissions from air travel are rising and will hamper the world’s efforts to curb climate change. The policy options are limited.
It is shaping up to be quite a dilemma: By all measures, modern humans are addicted to air travel, and yet despite considerable efforts by the airline industry to make airplanes more efficient, there is no practical way to produce zero-emission aircraft. Sadly, the only genuine way to reduce our collective carbon footprint from long-distance transport – given available technologies – is to significantly cut down on passenger and cargo flights.
