Increasing concerns over global warming and climate change have led to incrementing several attempts and advanced technology developments to tackle the excessive greenhouse gases emitted to the atmosphere. Recently, one of many technical strategies recently receiving a great attention is the application of membrane technology for greenhouse gas separation/capture. Such technology shows tremendous advantages over other conventional methods in terms of removal efficiency, compactness, and environmental friendliness. This paper reviews membrane technology, which has been innovatively developed for separation or capture of CO2. Many state‐of‐the‐art membrane developments as well as its applications to the post‐combustion treatment, which could be a promising approach for reducing CO2 emission from point sources, are thoroughly reviewed. Furthermore, a comprehensive survey on the future perspective of membrane technologies as a potential solution for CO2 removal and utilization was deliberated.
