Basically, carbon sinks are holding tanks for carbon or carbon compounds, like carbon dioxide (CO2). One of the largest reservoirs of carbon is the Earthâs hard rock crust. Over the eons sedimentary rocks were formed that contain loads of carbon compounds, including the hydrocarbons that we now use as fossil fuels.
Cement manufacturing is considered to be one of the highest carbon dioxide emitting industries in the world. The process emits around 900 kg of CO 2 for every ton of cement produced (Hasanbeigi et al., 2010) which constitutes approximately 5â7% of the global anthropogenic carbon dioxide emission (Chen et al., 2010).
