Sorry, by "standing in the way of" you mean "pushing for improvements to…and succeeding"? That "standing in the way"?
That's absolute hilarity. More ridiculous than when Laborites criticise their actions regarding Rudd's climate policy. Because at least that one appears to be a valid critique of the Greens if you don't have all the details (like how Rudd's policy would have no reduction in greenhouse emissions for 25 years). But this? Even with the most cursory of looks, the Greens did the right thing here.
