  1. Reserves are defined as both technically and economically proven given current market conditions. The header rows show the time horizon for which unextractable fossil fuels are assessed. Each row then shows the proportion and absolute volume of fossil fuel reserves which must remain unextracted for each column with the units in parentheses. Additional detail on the definition of reserves in this work is provided in the Methods. For a breakdown of countries included in the aggregated regions of TIAM-UCL, see Supplementary Table 26.
