Abstract
Carbon dioxide removal plays an important role in any strategy to limit global
warming to well below 2 °C. Keeping abreast with the scientific evidence using
rigorous evidence synthesis methods is an important prerequisite for sus-
tainably scaling these methods. Here, we use artificial intelligence to provide a
comprehensive systematic map of carbon dioxide removal research. We find a
total of 28,976 studies on carbon dioxide removal—3–4 times more than
previously suggested. Growth in research is faster than for the field of climate
change research as a whole, but very concentrated in specific areas—such as
biochar, certain research methods like lab and field experiments, and parti-
cular regions like China. Patterns of carbon dioxide removal research contrast
with trends in patenting and deployment, highlighting the differing develop-
ment stages of these technologies. As carbon dioxide removal gains impor-
tance for the Paris climate goals, our systematic map can support rigorous
evidence synthesis for the IPCC and other assessments.
