Air travel and transport accounts for two percent of all human generated greenhouse gas emissions, with airports contributing five percent to the overall aviation figure.

By adapting clean energy policies and technologies, eco-conscious airport operators hope to make a dent in these numbers and boost the industry’s environmental street-cred.

Other industry analysts however have a more cynical view, criticizing what they see as the ulterior motives behind green airport strategies.

“Not that they’re (green airport initiatives) inherently a bad thing, but it’s a waste of time when there are increasingly more flights and when airports are expanding,” says Joe Ryle of UK based anti-aviation expansion group, Plane Stupid.
