Can you have a zero carbon building? The answer is “no”. With John Butler (Sustainable Build Consultancy; CAT)

Zero Ambitions Podcast

If you’re looking to understand how to approach carbon accounting in the built environment, we’ve got you. Brought in to tackle some big questions around accounting for carbon we were joined by sustainable building expert John Butler.

Jeff’s been talking about getting John on for ages, for reasons he explains in the episode, and when we caught sight of an article he’s co-authored for the next issue of Passive House Plus we realised that we had the perfect excuse.

John provides us with a lot of experience and context for understanding the subject. It’s a nerdy episode too, in a good way, so it may bear a few listens because we cover a lot in an hour.

We start with a discussion of the process of creating the underlying EPD data for straw and go from there, through making net calculations, accounting for carbon stored in buildings, institutional guidance, concrete and carbonation.
