Twyford PhilHon PHIL TWYFORD (Minister for Economic Development): Thank you Madam Chair. Let me just respond briefly to Angie Warren-Clark's question about the climate change commitments that the Environment Committee helpfully inserted into the bill and the member asked really how those obligations will be incorporated into the Government policy statement and into the work of Kāinga Ora. So let me give some examples. So in relation to climate change mitigation I think one of the most important ways is that Kāinga Ora and all of its partners—local government and all of the other institutions that are part of the housing and urban development system—first need to take into account changing land use patterns in response to the effects of climate change. So for instance inundation being exposed to rising water tables and so not building in places that are vulnerable to rising sea levels whether it's at the beach or in areas where there is a lot of water inundation. That's the first thing.The second is that obviously one of the obligations will be to do everything we can to reduce carbon emissions and it's my expectation that we will in working closely with the independent climate commission end up with some kind of carbon budget for the built environment. Now you can see in transport which is responsible for about 20 percent of our emissions some of the things that we can do to reduce emissions. So the electrification of the vehicle fleet new sources of energy like hydrogen for heavy vehicles. All of those things are going to make a big difference. But in urban development there are some other things we can do. So reducing car dependency is one of the main things. So everything that we can do to build communities for instance with more urban intensification where people are in walkable neighbourhoods and have access to high-quality rapid transit and other forms of public transport walking and cycling. That will go a long way towards reducing the carbon emissions that are a direct result of the shape of our towns and cities. The third thing that is one of the main ways that an organisation like Kāinga Ora can make a difference is through the quality of the buildings and our homes in New Zealand still—notwithstanding the advances that have been made over the last 20 years in insulation and heating and the whole move towards healthy homes which we've reflected in the healthy homes guarantee that we legislated to make sure that all rental properties meet a certain standard and that they are warm and dry. We still have a long way to go and so the use of better building materials better design actually can make our homes more thermally efficient.Actually a really great example in recent times of where that's been done is the Hobsonville Point development developed by HLC where they used Government procurement procuring several thousand new homes and building a brand new suburb; they set standards for thermal efficiency in all those homes.Angie Warren-Clark: Brilliant.Hon PHIL TWYFORD: Yeah so all of those new homes are the equivalent of Homestar 6 or more. There's a requirement for greywater recycling. They're all double glazed. They are highly thermally efficient and that means not only are the people living in them happier and healthier but those homes are cheaper to run and they reduce our carbon emissions. Now when you play out those kinds of gains across thousands and thousands of new homes that are being built that adds up to pretty significant reduction in emissions.
