As the main greenhouse gas emitted due to human activities, carbon dioxide (CO2) is one of the primary contributors to climate change. Capturing some of this gas and keeping it out of the atmosphere is one approach that can help achieve lower global emissions. The natural world is responsible for most of this carbon capture, absorbing and storing CO2 in forests and wetlands, in the soil and in the ocean. In many cases, humans can help manage these natural processes. However, increasingly, societies are seeking to capture carbon using a new set of tools, collectively known as CCUS.
