Supplementary Data for "Declines in anthropogenic mercury emissions in the Global North and China offset by the Global South"

<b>Supplementary Data 1:</b> Country technical groupings for determining emission factors of Hg. WEurope - Western Europe. ECEurope - Eastern and Central Europe. U.S.&amp;CA - United States and Canada. RON - the rest of the Global North. SSA - Sub-Saharan Africa. NAME - Northern Africa and the Middle East. LATIN - Latin America. ROS - the rest of the Global South.<b>Supplementary Data 2:</b> The parameters of the abatement factor of sigmoid curves. PP - power plant combustion. IND - industry combustion. DR - commercial/residential/ transportation/agriculture combustion.<b>Supplementary Data 3:</b> Base year ASM population and data qualities by countries. ASM - artisanal and small-scale mining. ASGM - artisanal and small-scale gold mining.<b>Supplementary Data 4:</b> Gridded global Hg emission data for 1960 and 2021 (0.1°×0.1°). The NetCDF file Supplementary_Data_4.nc contains gridded data representing global Hg emissions for the years 1960 and 2021. It includes dimensions for latitude (1800 points, 90°N to 90°S), longitude (3600 points, 180°W to 180°E) and year (2 points, 1960 and 2021). The variables are latitude (values in degrees north), longitude (values in degrees east), year (1960 and 2021), and emissions (Hg emissions data in units of Mg per grid cell).
