The Intergovernmental Panel on Climate Change (IPCC) recognizes biochar as a central carbon dioxide removal (CDR) strategy, included in all scenarios to achieve net-zero emissions. However, scientific debate persists regarding the most appropriate methods for estimating the persistence of biochar-derived carbon in soils. These estimates are crucial for greenhouse gas inventories, carbon credit projects, and life cycle assessments (LCA), making it essential to map and critically analyze scientific output on this subject. This study conducts a bibliometric analysis of global production between 2009 and 2025, based on a Web of Science search using the terms “biochar,” “carbon sequestration,” and “modeling,” resulting in 448 articles.
