Reducing the concentration of carbon dioxide (CO₂) in the atmosphere to combat climate change is a global challenge. Direct air capture (DAC) incorporates a new set of technologies that directly remove CO₂ from the air; therefore, DAC can address emissions from any source. This paper begins by reviewing the literature on negative emission technologies (NET) to summarize the most recent technological developments. Further, a life cycle assessment (LCA) on one of the most recently developed technologies, the direct air capture and utilization (DAC-U) system is undertaken. DAC-U systems, like photovoltaic systems, can be installed in various locations, including homes, offices, and industrial settings, resulting in a compact, on-site system that may be suitable for modular and distributed deployment. Based on the LCA results, this article presents the CO₂ capture and reduction potential of the DAC-U system, with a focus on installations in households, and examines the willingness to adopt the system in Japan.
