While jetting to Inverness today I found an eco-label for airplanes in my Flybe in-flight magazine. The airline – proud of its fleet of new planes – publishes the environmental impact of its aircraft in terms of fuel, carbon dioxide, pollution and noise. Even without being widely disseminated these labels help to engender environmental literacy, which is the first step toward a cultural shift towards sustainability. And not just for consumers – as part of their report (pdf download) you can learn how to make your own eco-label if you own an airline, so that the ratings become useful to pressure airlines towards greater operating efficiency.
