It is estimated that the airline industry produces between 2-3% of all manmade CO2 emissions. All that jet fuel has to go somewhere. The atmosphere, mainly. And the number of people flying each year is increasing, dramatically. In 2004, almost 2 billion passengers took to the skies. By last year that number had more than doubled -- eclipsing the 4 billion mark for the first time. That's great news for the global economy. But what about global ecology?
Some airlines are taking environmental stewardship far more seriously than others. KLM is a prime example. The flag carrier of the Netherlands is spearheading innovations into this vital aspect of aviation. I sat down with Fokko Kroesen, the company's Corporate Environmental Manager to gain some insight into how.
