Not so ‘Wright’ after all, eh!

A takeoff towards greening the aviation sector is not financially viable. Can we ensure its sustainability?

The fact is – endless rounds of green summits between nations have ended up doing far greater harm than good. And the numerous flights that ferry officials and their teams back and forth to these meetings have a lot to do with that. Indeed, the reality of green transport will remain a distant dream without considering the aviation sector, which ranks right up there in the ranks of the world’s most polluting sectors of all time.

While flying is a day-to-day activity for those who can afford it, it’s a dream for many more who can’t. For the earth, however, it’s a growing nightmare the more such dreams get realised. Air travel is responsible for around 2.5% of CO2 emissions to the atmosphere. The effect of emissions has been known to increase nonlinearly with altitude. Environmental activists believe that aircraft are so harmful that one 747 takeoff creates the pollution level equivalent to setting a local gas station on fire – compare this to the fact that the year 2008 had over 77 million aircraft movements taking place globally. And the figure will only increase exponentially.

If this still looks like a non-issue, consider this report. A medical report from the University of Illinois, Chicago, estimated that the Chicago O’Hare International Airport affects the health of as many as 5-million people living in the surroundings. The report cites that if you live within 5-6 miles of an airport, you face a heightened risk of dying prematurely from environmentally induced cancer. Imagine the cumulative effect caused by around 49,000 airports operating worldwide (as per last statistics of Airports Council International). From damage due to chemicals like ethylene glycol, propylene glycol and NO2 to the harmful effects of aircraft noise, major health problems have been identified regularly.
