Natural gas can be used to complement or replace the use of coal or oil in factories and electricity generating stations to reduce sulphur dioxide and particulate emissions. Converting your car from gasoline to natural gas can reduce reactive hydrocarbon emissions by up to 40 per cent. Can natural gas help? me All combustion processes, including that of natural gas, produce nitric oxide. However, processed natural gas contains | _ hosulphur and contributes less to acid rain. As a result, the co-firing of coal or oil with natural gas can cut emissions and increase efficiency. Electric powerplants _ which combine natural gas and high- | sulphur oil have cut their sulphur dioxide emissions substantially. | Can natural gas help? z Natural gas combustion produces less _ carbon dioxide per unit ofenergythan = coal or oil, and releases little nitrous oxide. . While natural gas production does emit methane, the amount released is small, amounting to less than 2 per cent of total world methane releases. Substitution of natural gas for other fossil fuels will help to alleviate the problem of-global warming. Natural | The Natural Choice ©
