Recently, carbon neutrality has been promoted as a potentially practical solution to global CO2 emissions and increasing energy‐consumption challenges. Many attempts have been made to remove CO2 from the environment to address climate change and rising sea levels owing to anthropogenic CO2 emissions. Herein, membrane technology is proposed as a suitable solution for carbon neutrality. This review aims to comprehensively evaluate the currently available scientific research on membranes for carbon capture, focusing on innovative microporous material membranes used for CO2 separation and considering their material, chemical, and physical characteristics and permeability factors. Membranes from such materials comprise metal‐organic frameworks, zeolites, silica, porous organic frameworks, and microporous polymers. The critical obstacles related to membrane design, growth, and CO2 capture and usage processes are summarized to establish novel membranes and strategies and accelerate their scaleup. Carbon neutrality has been promoted as a potentially practical solution to globally rising CO2 emissions and energy‐consumption challenges. Among the numerous CO2‐neutral technologies, membrane gas‐separation is the best option to minimize the industrial carbon footprint. The design of microstructured membranes (zeolites, metal–organic frameworks, silica, and polymers) and obstacles related to membrane design, growth, and CO2 capture and usage are discussed with a view to establish novel membranes and accelerate their scale‐up.
