Also, as was pointed out by Barbara Kuriger earlier on, about emissions from methane, actually there's a lot of research now that's showing our emissions from methane are most likely at least one-third of what is being accounted for at the moment. So what does that really mean for us in New Zealand? That means the one thing we have to pursue is lowering transport emissions, and that will be hard because what will come from that, if we are not very careful, is energy poverty and that will affect those that can least afford it. So, once again, we need to have policies that are well-thought-out—are they going to be effective, are they going to be cost effective?—and we should have an upper limit on what they cost. The announcement, or re-announcement, of Helen Clark's 2007 carbon-neutral Government departments is all well and good, but what does it really mean? Thank you, Madam Speaker.
