Abstract Climate change mitigation will most likely rely on large-scale carbon dioxide removal (CDR). Often, only a few technology options are used, principally bioenergy, capture and sequestration, as well afforestation reforestation. If climate is based energy crops, the impact of CDR area demand may be significant. The CDR-specific usually not presented. This study compares portfolio prioritising biomass-based solutions to portfolios low cost, demand, high security, readiness in terms demand. model linked with an system include required for solar photovoltaics wind power supply whole energy–industry–CDR system. A quantitative qualitative comparison made using definitions gross net differentiation routes into biogenic, bio-technical, technical options. Gross differentiate total area, including spacing or gathering areas (gross) built-up (or unsuitable biodiversity) (net). We consider demands 500 GtCO 2 1.5°C target 1750 1.0°C by 2100. results indicate advantage regarding compared from crops. Including does lead significant can kept at ca. 1.0% (1.5°C) below 1.4% (1.0°C) land except biomass-prioritising portfolio, which has 3% both targets. Biogenic biotechnical estimated require up 9.7% today’s global cropland end century (net area). additional versus comparably small.
