What does CCU stand for in environmental technology?

CCU stands for Carbon Capture, Utilization, and Storage. This concept refers to a set of technologies designed to capture carbon dioxide emissions from sources like power plants and industrial facilities before they can enter the atmosphere. After capturing the carbon dioxide, it can either be utilized in various industrial processes, such as in the production of chemicals or fuels, or stored safely underground in geological formations for long-term sequestration. This process plays a significant role in mitigating climate change by reducing greenhouse gas emissions and is essential for transitioning to a more sustainable economy.

The other options do not accurately describe the established technological framework denoted by the acronym CCU. While they may reference relevant environmental concepts, they do not encompass the multifaceted approach of carbon capture, utilization, and storage that is critical for addressing climate challenges.
