Limiting anthropogenic carbon dioxide emissions constitutes a major issue faced by scientists today. Herein we report an efficient way of controlled capture and release of carbon dioxide using nature inspired, cheap, abundant and non‐toxic, industrial pigment namely, quinacridone. An electrochemically reduced electrode consisting of a quinacridone thin film (ca. 100 nm thick)on an ITO support forms a quinacridone carbonate salt. The captured CO 2 can be released by electrochemical oxidation. The amount of captured CO 2 was quantified by FT‐IR. The uptake value for electrochemical release process was 4.61 mmol g −1 . This value is among the highest reported uptake efficiencies for electrochemical CO 2 capture. For comparison, the state‐of‐the‐art aqueous amine industrial capture process has an uptake efficiency of ca. 8 mmol g −1 .
