Carbon dioxide Emissions Carbon dioxide emissions are those stemming from the burning of fossil fuels and the manufacture of cement. They include carbon dioxide produced during consumption of solid, liquid, and gas fuels and gas flaring. Human Emission Of Carbon Dioxide Human emissions of carbon dioxide (CO2) primarily result from the burning of fossil fuels for energy, transportation, and industrial processes. Key sources include: 1\. Electricity Generation: Fossil fuels like coal, oil, and natural gas are burned to produce electricity. 2\. Transportation: Cars, trucks, ships, and airplanes rely heavily on gasoline and diesel. 3\. Industry: Manufacturing processes, especially in cement and steel production, emit significant CO2. 4\. Residential Heating: Natural gas and heating oil used for home heating also contribute. How Much Carbon in The Ground? With around 1 500 billion tonnes of carbon found in the organic matter in soil worldwide, soils are the second largest active store of carbon after the oceans (40 000 billion tonnes). There is more carbon stored in soil than in the atmosphere (760 billion tonnes) and in vegetation (560 billion tonnes) combined. Globally, soils store an estimated 2,700 gigatons (Gt) of carbon, with 1,550 Gt being organic and 950 Gt being inorganic(The ISME Journal). This is significantly larger than the amount of carbon currently in the atmosphere (800 Gt) and far surpasses the amount in all living organisms combined (Earthopics).
