Don’t get me wrong, it’s always good to save power for economic reasons, but right now the biggest show in town is climate change. So when it comes to buildings and climate change, it is only the upfront embodied carbon in the materials that is relevant in New Zealand. Hands down the products that cause the most climate change damage are concrete and steel.
