二氧化碳捕获和封存（CCS）有可能发展成为应对气候变化的一个重要工具。鉴于社会目前对化石燃料的依赖，广泛采用CCS似乎是实现严格的气候目标所不可或缺的。我们认为，传统的CCS成为一个成功的气候减缓技术，这是必要的，必须在大规模运作，它可能需要补充空气捕获，直接从大气中去除二氧化碳。空气捕获CO2可作为防止CO2从储存中泄漏的保险措施，而且还可为处理汽车和飞机等移动的分散源的排放提供一种选择。
CO2 capture and storage (CCS) has the potential to develop into an important tool to address climate change. Given society's present reliance on fossil fuels, widespread adoption of CCS appears indispensable for meeting stringent climate targets. We argue that for conventional CCS to become a successful climate mitigation technology-which by necessity has to operate on a large scale-it may need to be complemented with air capture, removing CO2 directly from the atmosphere. Air capture of CO2 could act as insurance against CO2 leaking from storage and furthermore may provide an option for dealing with emissions from mobile dispersed sources such as automobiles and airplanes.
