No, it doesn’t mean very much at all:
George Bush last night pledged the United States to a "substantial" cut
in greenhouse gas as the west’s leading industrial nations agreed to
negotiate a new climate change deal within the next two years.
After
strong lobbying from EU leaders, Mr Bush agreed to "seriously consider"
a proposal that would result in a 50% cut in carbon emissions by 2050
but made it clear that US involvement depended on India and China being
included in any agreement.
It’s all too easy to miss the point that the US President actually has a great deal less power in such things than almost all of the European leaders. If Tony Blair signs us up to something then he can get it through Parliament as long as it’s not entirely stupid. Indeed, on the environment, given that it’s a sole European Union competence, if the assembled leaders sign up to it and the Commission agrees, there’s pretty much bugger all that anyone else can do about it.
However, the US President (of any party, this isn’t restriced to Shrub) doesn’t have that sort of power. Any treaty or international agreement has to get through the US Senate, and that’s a very tough proposition. From memory, didn’t Al Gore and Bill Clinton both agree to the original Kyoto? And when it was put to an indicative vote in the Senate, it was rejected 98-2? (Not quite sure about that voting number, but it was close to that.)
Getting whatever agreement there is through the Senate is what counts here, not what a President says at an international meeting.
