Construction Stored Carbon (CSC) refers to the amount of carbon dioxide (CO2) that is captured, stored, or sequestered within building materials during the construction or renovation process. It represents the carbon that is removed from the atmosphere and stored within the built environment. CSC takes into account the carbon stored in materials such as wood, timber, bamboo, or other carbon-intensive materials used in construction.

The concept of CSC recognizes that certain building materials have the ability to absorb and store carbon dioxide, thus helping to mitigate climate change by reducing greenhouse gas emissions. By incorporating carbon-storing materials into construction projects, the industry can actively contribute to carbon sequestration efforts. CSC is an important consideration for sustainable construction practices, as it helps to offset the carbon footprint associated with building activities and contributes to a more environmentally friendly built environment.
