  • But, to use a broad average, if the amount of C02 released during the production of a given unit of heat from natural gas is called one, oil gives off 1.6 and coal 2.0 units of carbon dioxide.How might some of the new technologies, such as the development of coal-based synthetic fuels, affect the rate at which C02 is emitted?Synfuels would probably make the situation a little worse.
