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, electric utilities, home firewood burning, incineration and waste, off-road vehicles and mobile equipment, the oil and gas industry, paints and solvents and other miscellaneous sources. The other ore and mineral industries include the aluminum industry, the asphalt paving industry, the cement and concrete industry, foundries, iron and steel industry, iron pelletizing mining and rock quarrying and the mineral products industry.
