Hon STUART NASH: The relevant agencies will apply the guide to decisions about new buildings with an estimated value of $9 million or over. They will record decisions about the way they choose design options at the outset. If an agency wants to proceed with an option that is not the lowest-possible carbon option available, then it must be signed off by the chief executive. It is great to see that the use of low-carbon materials will be embedded in decision making and design-thinking processes. It is also in line with the recommendations of the Climate Change Commission's final report. The commission has confirmed that we are making good progress to reduce emissions, but a step up is now required. The transition to a low-emissions future will create jobs and new opportunities for Kiwi businesses. By signalling our direction now, we will provide businesses with certainty to invest in new technology or processes.
