Business: What to do with embodied carbon in old buildings

Business commentator Nikki Mandow joins Kathryn to talk about the issue with greenhouse gas emissions from our buildings, be they operational (emissions from running the building) to embodied (what was used in its construction). How do we measure embodied carbon, and how should it be factored in to decisions about whether to retrofit a building or tear it down and start again? And Nikki also looks at Christchurch entrepreneur Adam Hutchinson of oVRcome, who's won a startup pitch at the Australian National Telehealth Conference in Sydney for his virtual reality software that helps people deal with their phobias.
