According to the Head of Sustainability at Virgin Atlantic, growing algae in large ponds could provide the aviation fuel of the future. “An algal pond the size of Belgium could meet all of aviation’s current fuel needs.” But at least half of the greenhouse gas emissions of aircraft come from water vapour (contrails) emitted at high altitude and from nitrogen oxides, and would be largely unaffected by the use of biofuels. So, in the absence of any breakthroughs in technology, we have these alternatives:
· Other sectors will have to make deeper cuts to compensate for rising aviation emissions
· We will have to place our faith in carbon offsets on a huge scale
· We will somehow have to learn to fly less and travel more slowly.
