Natural gas is called a clean fuel because:
• Natural gas burns cleaner than the other fossil fuels such as coal and oil due to the highly efficient combustion process, which produces very few by-products that are released into the atmosphere as pollutants.
• Natural gas produces 50-60% less carbon dioxide emissions compared to other fossil fuels.
• Due to the clean burning process, natural gas does not leave residues like soot or ash when compared to coal.
• Natural gas is non-toxic and is not poisonous to humans if inhaled in small volumes.
