Top 100 researchers in Biochar

The 100 most active researchers in Biochar since 2021, worldwide, the 50 most active based in Europe, and the same two lists by citations, from the CDR Researcher Census release 2026-11.4 (data as of 2026-11-05). 27,613 researchers have at least one CDR paper in this pathway since 2021; 27 of the most active 100 are based in Europe.

Jump to: most active, world · most active, Europe · most cited, world · most cited, Europe.

Activity sums the researcher’s CDR-relevant papers and preprints 2021–2026 in this pathway, each weighted by age with a half-life of 3 years: a paper from the as-of year counts 1.0, one from three years earlier 0.5, one from six years earlier 0.25. Citations count citations to those papers. Every row carries its rank in the other ordering. A preprint and its journal version count once where OpenAlex links them. Institution comes from the researcher’s own papers 2024–2026, else from the ORCID record, else from the OpenAlex author profile (marked †, the least reliable source). Corrections and removal: info@carbon-drawdown.de, done within five working days (privacy notice).

Most cited, worldwide top 100

The same researchers ranked by citations to their CDR papers since 2021. Citations lag by years, so this list favours established names and papers from 2021 and 2022; the activity rank beside each name says where the person stands on the other list.
