Hon MICHAEL WOOD: I can confirm that the embedded emissions involved in the construction of option i are higher than for option iv, noting that any significant construction project in transport will have significant embedded emissions. But what I also note is that clearly in the Government's announcement we confirmed that option i will be strongly linked with a higher model of urban intensification, which, when taken together, will offer significant carbon reductions and enable us to reach a point of carbon neutrality and then savings by the mid-2030s.
