KEY FINDINGS
• Federal agencies have historically funded some carbon removal-related RD&D projects in all of the major categories
recommended in the NASEM report; however, that funding has been scattered and piecemeal as the United States does
not have a dedicated research program for carbon removal.
• Historical funding was concentrated by carbon removal category in carbon sequestration—approximately one-half
(49 percent) of estimated federal funding for about 20 percent of the total projects identified in the bottom-up analysis.b
• Slightly more than half of the remaining historical funding—$1,879.5 million—was targeted to various forms of terrestrial
and biological carbon capture.
• Very little funding was invested historically in other technologically enhanced forms of carbon removal—for example,
$10.9 million total (spanning an 11-year period) for direct air capture and $24.7 million total (over a 17-year period)
for research on carbon mineralization.
For all categories of carbon removal-related RD&D, the historical baseline investments were significantly lower than the future
funding levels recommended in the NASEM report. Figure 1 displays historical RD&D investment levels identified in the analysis
along with the NASEM recommended future levels for each major category of carbon removal. Note that these two sets of data
are not directly comparable. While the NASEM committee was generally aware of many of the historical carbon removal-related
RD&D activities, it did not have detailed available data on historical investment levels, as shown in Figure 1. Consequently, the
NASEM report identified recommended future funding levels for various elements of the carbon removal-related RD&D portfolio
that are primarily in addition to existing levels, but it did not make any assumptions as to what a future baseline spending level
might be in the absence of the report recommendations. Similarly, the fact that this analysis was able to identify in some detail
the historical levels of investment in carbon removal-related RD&D should not be viewed as a future budget baseline funding level
in the absence of affirmative congressional action on the fiscal year (FY) 2020 (and future) budgets. Nonetheless, comparing the
historical levels of investment with recommended future funding levels does illustrate the scale of future funding challenges to
the implementation of the NASEM report. The challenges are particularly acute for implementing the NASEM recommendations for
RD&D on direct air capture, mineralization, and coastal and oceans carbon removal:
• NASEM-recommended future funding needs for direct air capture are 100 to 200 times the historical baseline level;
• NASEM-recommended future funding needs for carbon mineralization are nearly 30 times the historical baseline level;
• NASEM-recommended future funding needs for coastal and oceans carbon removal-related research are nearly 30 times
the historical baseline level; and
• Even in the categories of terrestrial and bioenergy and geologic sequestration, the future funding levels recommended in
the NASEM report represent significantly higher future funding levels compared with the historical baseline estimates.
