Scaling up enhanced rock weathering for equitable climate change mitigation Administrative dataset In this study, we included a total of 180 countries using the World Bank’s Global Administrative Divisions data49. This dataset classifies the world into seven regions: North America, Europe & Central Asia, East Asia & Pacific, Latin America & Caribbean, Middle East & North Africa, South Asia, and Sub-Saharan Africa (Fig. S1a), as well as four income groups: low income, lower-middle income, upper-middle income, and high income (Fig. S1b). We also incorporated county-level administrative boundaries from the GADM database50, covering over 30,000 counties (Fig. S1c). CHAT dataset We used the Cross-country Historical Adoption Technology (CHAT) dataset51, an aggregation of country-level statistics sourced from national income accounts and various multilateral agencies. The CHAT dataset contains annual information on technology use for 161 countries from 1820 to 2003, encompassing 104 technologies across sectors, such as transportation, communication and IT, industrial, agricultural, and medical. Climate data We derived global annual mean temperature, cumulative precipitation, and cumulative evapotranspiration for the period 1980–2023 from the TerraClimate dataset52, which provides monthly climate and climatic water balance variables for global terrestrial surfaces at a 5-km spatial resolution. Specifically, annual mean temperature was calculated as the average of monthly minimum and maximum temperatures (from the ‘tmmn’... https://www.nature.com/articles/s44458-026-00034-w
