Global warming is a critical issue resulting partly from increasing carbon dioxide emissions. Technologies have been developed to capture carbon dioxide followed by storage or utilization, yet techniques are limited by the use of toxic solvents and the generation of harmful by-products. Research in green chemistry has designed green solvents which are non-toxic, efficient and environmentally friendly. Here we review green solvents employed for carbon capture, with emphasis on ionic liquids, deep eutectic solvents and liquid polymers. Solvent performance depends on temperature, density and viscosity. Deep eutectic solvents appear as the most advanced solvents with capacities reaching up to 4.292 g CO₂ per g of solvent. Ionic liquids have shown CO₂ uptakes of 4.72 mol of CO₂/mol of solvent, but are less efficient on average. Liquid polymers display capacities of up to 1.357 mol of CO₂/mol of solvent.

全球变暖是一个关键问题，部分原因是二氧化碳排放量增加。已经开发了捕获二氧化碳然后存储或利用的技术，但是该技术受到有毒溶剂的使用和有害副产物的产生的限制。绿色化学方面的研究设计了无毒，高效和环保的绿色溶剂。在这里，我们回顾用于碳捕获的绿色溶剂，重点是离子液体，深共熔溶剂和液体聚合物。溶剂性能取决于温度，密度和粘度。深共晶溶剂是最先进的溶剂，每克溶剂的容量最高可达4.292 g CO ₂。离子液体已显示CO ₂ 4.72摩尔CO的吸收量₂ / mol溶剂，但平均效率较低。液态聚合物显示出高达1.357 mol CO ₂ / mol溶剂的容量。
