Global, Regional, and National Fossil-Fuel CO2 Emissions (1751 - 2014) (V. 2017)

Publications containing historical energy statistics make it possible to estimate fossil fuel CO2 emissions back to 1751. Etemad et al. (1991) published a summary compilation that tabulates coal, brown coal, peat, and crude oil production by nation and year. Footnotes in the Etemad et al.(1991) publication extend the energy statistics time series back to 1751. Summary compilations of fossil fuel trade were published by Mitchell (1983, 1992, 1993, 1995). Mitchell's work tabulates solid and liquid fuel imports and exports by nation and year. These pre-1950 production and trade data were digitized and CO2 emission calculations were made following the procedures discussed in Marland and Rotty (1984) and Boden et al. (1995). Further details on the contents and processing of the historical energy statistics are provided in Andres et al. (1999). The 1950 to present CO2 emission estimates are derived primarily from energy statistics published by the United Nations (2017), using the methods of Marland and Rotty (1984). The energy statistics were compiled primarily from annual questionnaires distributed by the U.N. Statistical Office and supplemented by official national statistical publications. As stated in the introduction of the Statistical Yearbook, "in a few cases, official sources are supplemented by other sources and estimates, where these have been subjected to professional scrutiny and debate and are consistent with other independent sources." Data from the U.S. Department of Interior's Geological Survey (USGS 2017) were used to estimate CO2 emitted during cement production. Values for emissions from gas flaring were derived primarily from U.N. data but were supplemented with data from the U.S. Department of Energy's Energy Information Administration (1994), Rotty (1974), and data provided by G. Marland. Greater details about these methods are provided in Marland and Rotty (1984), Boden et al. (1995), and Andres et al. (1999).

依托收录历史能源统计数据的相关文献，可将化石燃料二氧化碳（CO₂）排放量的估算年限回溯至1751年。Etemad等（1991）发表了一份汇总统计数据集，按国别与年份列示了煤炭、褐煤、泥炭及原油的产量情况。该文献的脚注将能源统计时间序列的覆盖范围延伸至1751年。Mitchell（1983、1992、1993、1995）先后发表了多份化石燃料贸易的汇总编录，其成果按国别与年份统计了固体燃料与液体燃料的进出口情况。1950年之前的上述产量与贸易数据已完成数字化处理，并按照Marland与Rotty（1984）以及Boden等（1995）所述的计算流程完成了二氧化碳排放量的核算。Andres等（1999）对本次研究使用的历史能源统计数据的内容与处理细节给出了更为详尽的说明。
1950年至今的二氧化碳排放量估算值，主要依托联合国（2017）发布的能源统计资料，采用Marland与Rotty（1984）提出的计算方法得到。该批能源统计数据主要由联合国统计署发放的年度问卷汇总编制，并辅以各国官方统计出版物的相关数据。正如《联合国统计年鉴》引言中所述：“在少数情形下，官方数据源会辅以其他来源的资料与估算值——此类补充资料需经过专业评审与论证，且需与其他独立数据源保持一致性。”美国内政部地质调查局（USGS 2017）提供的数据，被用于估算水泥生产过程中产生的二氧化碳排放量。天然气燃除产生的排放量数值主要源自联合国统计数据，同时辅以美国能源部能源信息署（1994）、Rotty（1974）以及G. Marland提供的相关数据。关于上述计算方法的更多细节，可参考Marland与Rotty（1984）、Boden等（1995）以及Andres等（1999）的相关文献。
