Hon MICHAEL WOOD: Yes. The emissions reduction plan is Government policy and something that we give great priority to. We will be considering that as we consider the best options to take mass rapid transit in Wellington forward, as we will be considering the investment objectives. I note that there was a 40 percent weighting on the mode shift objective within the Let's Get Wellington Moving programme. Again, I would just note to the member that none of these choices and trade-offs are necessarily as simple and didactic as saying it's "A versus B"; the trade-offs are often very complex. For example, as I said before in a previous question, the ability to significantly uplift urban housing along this corridor is potentially one of the ways that we can provide the greatest medium- to long-term carbon savings.
