Hon MICHAEL WOOD: In the first instance, I do just reflect back on my comments, which note that any form of significant construction involves a degree of embedded carbon across any of the options that we are looking at. The key point is what we then enable by way of carbon reduction in the long run, and our view is that option i, particularly with the intensified housing model, provides that. But what I will say to the member is that we are ambitious to make progress as soon as possible and we have engaged with officials to ask them to look at accelerated options, including the phasing of options, to bring forward the benefits of light rail within the programme.
