On the one hand, this is probably to be expected. James Shaw is the Climate Change Minister, and the status quo is (mostly) his policy. So of course he's focused on fixing the bits where Labour has over-ruled him. But on the gripping hand, it is clear that what we are currently doing is simply nowhere near what we need to be doing. And on that front, a wishy-washy promise to simply "price" agricultural emissions seems weak, leaving open the crucial questions of "how much" and "how much will you shrink the sector by". Because that dirty, inefficient, polluting sector needs to shrink if we are to lower emissions (and improve water quality), and pretending it doesn't does no-one any favours.
This is still the best climate change policy on offer. But I expected more from the Greens. And if they're not going to offer what's required, then who will?
