Strong climate policies do not need a new EU treaty

Do we need a new European treaty in order to save our climate? EU President Barroso certainly seems to think so.
According to today’s Financial Times, the Commission President has warned future UK prime minister Gordon Brown not to block a compromise deal on a watered-down European treaty. If the UK would fail to agree to the new compromise, it might undermine efforts to fight climate change and reach a Doha trade deal. With this threat, Barrosos is putting pressure on Mr Brown, according to the FT.
Well, I am sure that Blair’s successor is not that dumb
There was nothing in the old, failed draft Constitution, nor in the current compromise which, in any way, would make a big difference as to Europe’s ability to tackle global warming. Suddenly now for the Commission President any reference to climate change seems a good argument to use to win his power fights. What happened to the Lisbon agenda, Mr President? Where did you forget your old battlehorse?
