Flying = hatred of environment.

If an environmentalist fly’s in an airplane, they often get derided for it. Bob Brown, Al Gore, and now Leonardo DiCaprio – they wheel out the same argument all over again. Leo cracked it at Cannes when this false contradiction was put forward to him.

Did you fly on a gas-guzzling jet to arrive at the premier of his Eco-doco?
No, I took the friggin’ train.

(Paraphrased – “friggin’” was added for dramatic effect.)

A Toyota Prius gets 5L/100km.
Modern commercial flights get 3.5L/100km.

Aviation and jet fuel have around the same energy (MJ) per litre as petrol, around 20% of CO2 emissions in the US are from cars, around 4% from planes, etc. etc.

There are many other factors to consider, but the fact remains – unless you’re car-pooling your freaking Prius, cycling, or taking bus/rail, it’s better to fly.

The real issue is whether the flight is necessary at all. (Oh and private jets are ridiculously inefficient, and do not apply.)
