In modern green building standards like LEED or GRIHA, Carbon Sequestration in construction refers to
- AReleasing CO2 during the manufacturing of cement.
- BThe use of coal-based energy for site operations.
- CThe process by which building materials capture and store atmospheric CO2.Correct
- DIncreasing the carbon content in structural steel to make it harder.

Carbon Sequestration in Building Materials
Formula
N/A
Step-by-step solution
1. Define the term "Carbon Sequestration" in the context of modern green building standards like LEED or GRIHA. 2. Recognize that it refers to the process where building materials capture and store atmospheric carbon dioxide. 3. Match this concept with the options and select Option (c) as the correct choice.
Explanation
Carbon sequestration in construction means using eco-friendly materials, like timber or specialized concrete, that absorb carbon dioxide from the air and store it permanently inside the building structure. This prevents harmful greenhouse gases from contributing to global warming.
Shortcut
To easily remember Carbon Sequestration in construction, use the mnemonic "Sequestration = Trap & Store": - Carbon: Refers to atmospheric carbon dioxide (CO2). - Sequestration: Means trapping and permanently storing CO2 inside green building materials instead of releasing it into the air.
Common mistake
A common mistake is selecting option D by confusing environmental "carbon sequestration" with the chemical addition of carbon to steel to increase its hardness. Another frequent mistake is selecting option A by confusing carbon sequestration (capturing and storing carbon) with carbon emissions generated during cement manufacturing.
Correct answer: C) The process by which building materials capture and store atmospheric CO2.
