Carbon dioxide is one of the most important greenhouse gases, released both naturally and as a result of human activities into the Earth’s atmosphere. Naturally, it enters the atmosphere through processes such as respiration of living organisms, volcanic eruptions, and the decomposition of organic matter. However, over the past two centuries, industrial human activities have significantly increased the concentration of this gas in the atmosphere. Global warming is arguably the most critical consequence of elevated atmospheric CO2 levels as a greenhouse gas. This review initially outlines the sources of carbon dioxide emissions, followed by a brief examination of the natural mechanisms for CO2 absorption. Given that in recent decades, a balance between emission and absorption rates has not been maintained—leading to its accumulation in the atmosphere and causing various environmental issues—this study explores different methods of emission reduction and CO2 capture. A comparison of various carbon capture techniques indicates that, currently, chemical absorption using amines is the most cost-effective option due to its technological maturity and commercial viability. The article further discusses carbon dioxide transportation methods and finally reviews its potential industrial applications.
