The CAS Content Collection is the largest human-curated collection of published scientific knowledge, suitable for quantitative analysis of global scientific publications against variables such as time, research area, formulation, application, and chemical composition. In this work, terms related to CO2 capture and sequestration were used for document search in combination with terms related to atmospheric CO2 or its environmental effect. About 18,500 documents containing relevant terms in title, abstract or CAS indexed areas were found with publication years between 2001 and 2021 (See Supplemental information for method descriptions of search strategy and terminologies). It is worthwhile to note that, to reduce the noise level, this is not an exclusive search to include all the related documents, but rather a sample pool with a significant amount to represent the trend.
