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), electric utilities, home firewood burning, incineration and waste, 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, the cement and concrete industry, foundries, the iron and steel industry, iron pelletizing, mining and rock quarrying and mineral products industry.
