The indicator reports emissions from human-related activities only. It does not include emissions from natural sources such as forest fires or volcanoes. The category ""other sources"" includes agriculture (livestock, crop production and fertilizer), building heating and energy generation, home firewood burning, manufacturing, the oil and gas industry, transportation (road, rail, air and marine) and other miscellaneous sources. Other ore and mineral industries include the aluminum industry, the asphalt paving industry, cement and concrete, iron and steel industries, iron ore industry and mining and rock quarrying.
