Carbon dioxide (CO 2 ) is the essential ozone harming gas and its emissions ends up in worldwide temperature alteration that leads to climate change. CO 2 adsorption on solid materials such as zeolites, carbonaceous materials, metal organic frameworks and silicaisone of the efficient method for carbon dioxide removal. This review focuses on polymer-based adsorbents for CO 2 capture. Porous organic polymers like hyper-cross linked polymers (HCPs), covalent organic frameworks (COFs), conjugated microporous polymers (CMPs) and covalent triazine-based frameworks (CTFs) display CO 2 catching limit of around 3 to 6 mmol/g at 273K and 1 bar. Polymer such as polyethyleneimine when incorporated with adsorbents offers improved CO 2 adsorption at higher temperature. CO 2 adsorbents developed from polymer waste can play a dual function in environmental pollution control. In industrial packed columns, polymer composites are considered as superior choice for CO 2 capture.
