When we talk about climate change on this show, and what causes it, we are usually talking about gases that come from vehicles or from the electricity sector. 

But what about the built environment? This week: we’re talking about the embedded emissions in our buildings.

There’s the natural gas that gets burned in them, and there’s all the electricity that it takes to power them. 

And then there’s another category – all the upfront energy that went into making the buildings in the first place. That’s called “embodied carbon” or “embedded carbon” or sometimes “upfront carbon.” 

In the next few crucial years when we can bend the arc of climate change, most of the emissions that come from buildings are going to come from the embodied carbon. So how we choose to build buildings really matters. 

Our senior editor Ingrid Lobet has a special interest in buildings and wrote recently about embodied carbon for Greentech Media. Read that article here.

Just before everything shut down with the pandemic several months ago, Ingrid was at a conference on this subject organized in part by Ed Mazria. Mazria has been at the forefront of a growing faction of builders, engineers and designers intent on remaking buildings into a climate solution. She spoke with him about the biggest opportunities in decarbonizing buildings.
