aFor inventory names and references, see Table 1.

bSector-specific estimates are not available at country level in WHET, so the Australian sectoral contributions have been estimated here by scaling the Oceania totals (including Australia, New Zealand, Papua New Guinea, and Pacific Islands) by the Australia-to-Oceania ratio found in the total emissions (0.81).

cBased on the following categories: coal combustion in power plants and combustion of oil in Nelson et al.; stationary combustion—power plants, industry, and domestic/residential/other (coal, oil, gas) in AMAP/UNEP; coal and oil in WHET; and power generation, industry (combustion), and residential (combustion) in EDGARv4.tox2.

dBased on the following categories: gold smelting and gold mining in Nelson et al.; large-scale gold production in AMAP/UNEP; gold, large-scale and gold, artisanal in WHET; and gold production (large-scale and small-scale gold production, mercury production, and chlor-alkali mercury cell tech) in EDGARv4.tox2. Note that EDGARv4.tox2 includes mercury production and chlor-alkali industry in this category, whereas these are not included in the other inventories.

eBased on the following categories: copper, zinc, lead, and silver smelting, alumina production from bauxite, primary ferrous metal production, production of recycled ferrous metals, and copper, zinc, lead, and silver mining in Nelson et al.; ferrous metal production (primary pig iron and steel, secondary steel), nonferrous metal production (primary copper/lead/zinc, primary aluminum, mercury production) in AMAP/UNEP; copper, zinc, lead, iron, and steel in WHET; and iron and steel and nonferrous: zinc, copper, and lead in EDGARv4.tox2.

fBased on the following categories: chlor-alkali production, biomedical waste incineration, electrical and electronic switches, light sources, measuring equipment, laboratory equipment, dental amalgam, batteries, and crematoria/cemeteries in Nelson et al.; cremation emissions, waste (other waste), waste incineration (controlled burning) in AMAP/UNEP; waste, caustic soda, and additional air from Horowitz et al. (2014) in WHET; and solid waste incineration in EDGARv4.tox2.

gBased on the following categories: coke production, cement and lime production, oil refining pulp and paper production in Nelson et al.; cement production (raw materials and fuel, excluding coal), oil refining in AMAP/UNEP; cement in WHET; and cement, transformation industry, and refineries (combustion) in EDGARv4.tox2.

hSolid waste incineration only; other forms of waste and cremation emissions are not included in EDGARv4.tox2.
