Climate Judgement

Now this is must-read stuff. From the Australian VoteClimate site, a climate change policy analysis for the Federal election. (They disendorced a Greens candidate in the Victorian election due to failed support for a wind farm, and there deoesn't appear to be any bias - so these guys don't seem to be partisan hacks, which is excellent.)
There are a few striking differences in the minor parties, but not a great deal in the major two. The Socialist Alliance is the greenest party, followed by the Greens, Democrats, and trailing quite a way behind is Labor then Liberal.

It's a good example of how pragmatic the Greens are - at least when compared with Socialist Alliance. And how there isn't a single party with zero-emission goals.
