Emissions of greenhouse gases have been a major

problem for the world for many decades. Carbondioxide is one of the main greenhouse gases,

accounting for 64% of total emission.

he major C!" emission source is industrial

activities such as power generation, iron and steel

production, cement manufacture, and oil and natural

gas production and refining, which collectively

contribute approximately one third of the total C!"

emissions

&ajor problem is global warming. 'f carbon dioxidelevels continue upward, further warming could have

dire conse(uences, resulting from rising sea levels,

agriculture disruptions, and stronger storms stri)ing

more often.

Caron sequestration:-

Carbon se(uestration is capturing the carbon

dioxide produced by burning fossil fuels and

storing it safely away from the atmosphere

he process of removing carbon from the

atmosphere and depositing it in a reservoir. *hen

carried out deliberately, this may also be referred to

as carbon dioxide removal.
