You'll see the acronyms CCS and CCUS used a lot around here. Let's first go over what those mean.

CCS: Carbon Capture and Sequestration. This is the process of capturing CO2 emissions either from a direct source (a smokestack, for example) or from the atmosphere. After the emissions are captured, they're stored underground (sequestered) and kept out of the atmosphere. The emissions aren't recycled but are sometimes used to extract oil through a process known as Enhanced Oil Recovery (EOR).   

CCUS: Carbon Capture, Utilization, and Sequestration. Now, here's where things get exciting. After the CO2 is captured, it's used to create new materials and products. Instead of just sequestering the CO2, it's utilized to make everything from fuel, concrete, and shoes, to cleaning products, plastics, and food. This allows us to actually recycle our emissions and create a circular carbon economy.

Whether the CO2 is recycled to make new products or sequestered underground, both practices can help us achieve negative emissions - where we're removing more CO2 from the atmosphere than we're putting in.
