In order to reach carbon neutrality, GHG emissions from all sectors of society need to be strongly reduced. This especially applies to the construction sector. For those emissions that remain hard to reduce, removals or compensations are required. Such approaches can also be found within the built environment, but have not yet been systematically utilized. This paper presents a review of possible carbon storage technologies based on literature and professional experience. The existing technologies for storing carbon can be divided into 13 approaches. Some are already in use, many possess the potential to be scaled up, while some presently seem to only be theoretical. We propose typologies for different approaches, estimate their net carbon storage impact and maturity, and suggest a ranking based on their applicability, impact, and maturity. Our findings suggest that there is an underutilized potential for systematically accumulating atmospheric carbon in the built environment.

为了实现碳中和，需要大力减少社会各部门的温室气体排放。这尤其适用于建筑行业。对于那些仍然难以减少的排放，需要清除或补偿。这种方法也可以在建筑环境中找到，但尚未系统地使用。本文根据文献和专业经验对可能的碳储存技术进行了回顾。现有的碳储存技术可分为13种方法。有些已经在使用中，许多具有扩大规模的潜力，而有些目前似乎只是理论上的。我们为不同的方法提出类型学，估计它们的净碳储存影响和成熟度，并根据它们的适用性、影响和成熟度建议排名。
