Worldwide, we use four or five billion with a B tons of cement every year.

And then cement is about 10% of concrete.

So we use 40 to 50 billion with a B, tons of concrete,

every year globally.

Welcome to the Fine Home Building Pro Talk podcast, a regular discussion with building industry professionals.

Today I'm joined by Cody Finky, CEO of Brimstone Energy, a startup trying to solve the carbon problem of Portland Cement.

You can find the Fine Home Building Pro Talk podcast and the original Fine Homebuilding podcast at finehomeowning.com slash podcast.

You can leave feedback and ask questions there too.

Cody, thanks a million for being on the show.

Yeah, thank you, Patrick. I appreciate it.

I want to get right to it. Tell me what the heck you're doing.

What is, tell me about your company, first of all, and what you're trying to do.

Yeah, so thanks for asking. So Brimstone Energy is trying to globally decarbonize the world of cement. So I'm going to double-click on that a little bit

because it's a new topic for a lot of people. So cement or ordinary Portland cement is the binder in

concrete. So concrete is the building material and cement is what makes it stick together. And concrete is an interesting material.

It's actually the most consumed human made material on the planet, but it has a really large carbon impact.

So almost 100% of the carbon comes from the production of cement, the cement that's in the concrete.

And all told, cement is responsible for about 5.5% of greenhouse gas emissions or 8% of CO2 emissions.

So there's a few ways to say that that are more impactful.

So one is if the cement industry were a country, it would be the third largest emitter after China and the United States.

Another way to say it is the total emissions from cement are about the same as cars.

So all passenger vehicles make up maybe 6.5% of greenhouse gas emissions.
