Will consumers use products made from captured CO2?

Would you drink carbonated beverages made with carbon dioxide captured from the smokestack of a factory or power plant?

How would you feel if that captured carbon dioxide were in your child’s toys, or in the concrete under your house?

The technology to capture climate-warming carbon dioxide emissions from smokestacks, and even from the air around us, already exists; so too does the technology to use this carbon dioxide to make products such as plastics, concrete, carbonated drinks, and even fuel for aircraft and automobiles.

That combination—known as carbon capture and utilization—could take up billions of tons of carbon dioxide emissions if the technologies were adopted across a range of sectors worldwide.

The key to carbon capture and utilitization’s potential is that these products have economic value. That value can give companies the incentive to deploy the technology at the global scale necessary to slow climate change.

Carbon capture technology itself isn’t new. Initially, captured carbon dioxide was used to force oil and gas out of old wells. Once emissions are captured, typically from an industrial smokestack via a complex chemical filter, they can be pumped deep underground and stored in depleted oil reservoirs or porous rock formations. That keeps the carbon dioxide from reaching the atmosphere, where it can contribute to climate change.

But storing carbon dioxide in the ground doesn’t create a new product. The absence of an economic return—coupled with concerns about storing carbon dioxide underground—have slowed the adoption of the technology in most countries.

How do people feel about carbon dioxide-based products?

For many products made with captured carbon dioxide, success will depend on whether the public accepts them.

Two of us recently conducted one of the first large-scale studies to examine public perception of carbon dioxide-based products in the U.S. to find out. We asked over 2,000 survey participants if they would be willing to consume or use various carbon dioxide-based products, including carbonated beverages, plastic food storage containers, furniture made with foam or plastic, and shatterproof glass.

We found that most people knew little about carbon capture and use. However, 69% were open to the idea after learning how it worked and how it helped reduce the emissions contributing to climate change.

There was one exception when we asked about different types of products people might be willing to use: Fewer people—only 56%—were open to the idea of using captured carbon dioxide in carbonated beverages.

Safety was a concern for many people in the survey. One-third didn’t know if these products might pose a health risk, and others thought they would. It’s important to understand that products made with captured carbon dioxide are subject to the same safety…
