Copenhagen Golden

UK: Has Gordon Brown missed a golden opportunity to show his his green credentials?

According to reports Gordon Brown (and no doubt a group of acolytes and the Press) will be flying to the Copenhagen Climate Summit in December (private charter?)
Why?
Has he not heard of the high-speed Channel Link and the Channel Tunnel.

I can remember when the term green meant naive, uninformed, inexperienced, that sort of thing. So maybe he has actually shown his green credentials.
