近年来，直接空气捕集(DAC)被认为是一种很有前途的大气二氧化碳去除(CDR)方法，也被称为负排放。然而，由于可能需要去除的数量，像DAC这样的CDR技术只有在本世纪中叶左右迅速达到10亿吨规模时才会变得与气候相关。在这里，我们将简要介绍DAC，特别是瑞士气候公司开发的模块化低温DAC技术。我们讨论了潜在的共同利益，特别是与联合国可持续发展目标(SDGs)有关的潜在共同利益，并最后就如何及时实现气候相关规模提出了一些政策方法。
In recent years Direct Air Capture (DAC) has established itself as a promising approach to atmospheric Carbon Dioxide Removal (CDR) also referred to as Negative Emissions. However, due to the amounts likely needed to be removed CDR technologies like DAC will only become climate relevant if they rapidly reach gigaton scale, around the middle of this century. Here we give a brief insight into DAC and in particular, the modular low temperature DAC technology developed by Climeworks of Switzerland. We discuss potential co benefits, in particular in relation to the Sustainable Development Goals (SDGs) of the United Nations and conclude by suggesting some policy approaches on how a climate relevant scale could be achieved in time.
