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.
