Fossil + Land use Given total fossil Summed Fossil Gas Oil Coal Cement Flaring Other Per Capita Fossil Land Use (H&N2017) The format of this spreadsheet is akin to Boden et al (2017), NDP-030 (hereafter 'Boden 2017'): https://cdiac.ess-dive.lbl.gov/ftp/ndp030/global.1751_2014.ems However, I've substituted newer data from the Global Carbon Project (GCP). I also made another, similar, spreadsheet, using data from the BP Statistical Review of World Energy 2022, instead of GCP data: https://sealevel.info/global.1751_2021.ems7.txt Note that GCP gives emissions in MtCO2, rather than MtC. For consistency with CDIAC's global.1751_2014.ems spreadsheet, I converted to MtC by multipling GCP's figures by (12.0107 / 44.0095). GCP figures average somewhat higher than the BP figures. The enormous precision with which the numbers are given does not imply that they are known that precisely. My guess is that most of the fossil carbon emission figures are known to within about +/- 10% (but that's just a guess). Estimated land use change effects are from H&N 2017, as updated by GCP (and they're much less precise than the fossil carbon emission figures): https://sealevel.info/carbon/feedbacks/National_LandUseChange_Carbon_Emissions_2022v1.0_mod1.xlsx Houghton, R.
