The cost-effective capture of carbon dioxide (CO{sub}2) from the point sources for its reduction the atmosphere offers many challenges in materials science. Novel CO{sub}2 capturing approaches using chemical, physical and biological methods are in the research stage and are aimed to minimize the cost. Appropriate materials development , which can withstand' required temperature or pressure as the case may be for CO{sub}2 emanating from coal gas or industrial waste gases form the minimum condition. Other requirements are reclyclability of material and cost of separation. Nano-material composites can be more effective in selective capture of CO{sub}2 and can offer solutions for large-scale separation process. Nano-porous material catalysis can enhance the reaction rate of CO{sub}2 with other chemicals and thus help in capture of CO{sub}2 and convert it into value added products. This paper reviews recent industrial scale developments. In the Indian context, R&D priority areas in CO{sub}2 capture process development with a focus on energy industry are presented.
