Papers counted in the census

21 CDR-relevant papers and preprints since 2021 count for the top lists, by pathway: Biochar 18, Enhanced Weathering 7, Cross-cutting CDR 3. A paper tagged with two pathways counts in both lists. Preprint and journal version are merged where OpenAlex links them; where it does not, both appear.
