Good points Kingfisher.
Perhaps if a few airlines got together, grew some b*lls and point blank refused to acknowledge the ETS, then maybe we would get somewhere.
I can't exactly see a fleet of airliners being impounded in the EU for non payment.
The people who run the scheme are the biggest bunch of numpties going anyway, maybe they will form a human barrier in their tree hugging t-shirts to stop aircraft that haven't purchased enough carbon credits.
