#### **Abstract**

The steady increase of anthropogenic CO2 in ambient air, owing to the fossil fuel, power plants, chemical processing and deforestation caused by the usage of land, is a key challenge in the on-going effort to diminish the effect of greenhouse gases on global climate change by developing efficient techniques for CO<sup>2</sup> capture. Global warming as a consequence of high CO<sup>2</sup> level in the atmosphere is considered as one of the major long lasting problems in the twenty-first century. Concern over these major issues with regard to severe climate change and ocean acidification motivated us to develop the technologies that capture the evolved CO2 from entering into the carbon cycle. Therefore, CO2 capture and storage technology is attracting increasing interest in order to reduce carbon level in the atmosphere which in turn mitigates global climate issues. In this regard, highly efficient adsorbents e.g.; zeolites, alkali metal oxides, activated carbon, porous silica show considerable progress in post combustion CO2 capture. Recently, metal-organic frameworks (MOFs), porous organic polymers (POPs), porous clays, N-doped carbon etc. are explored as versatile and quite elegant way for next-generation CO<sup>2</sup> capture. In this chapter, we will discuss the broad prospect of MOFs, POPs, nanoporous clays and porous carbon for CO2 storage and sequestration through utilization of their nanospace chemistry.
