Lignite’s high moisture content and lower carbon content results in more carbon dioxide emissions than harder black coals. In these power plants the coal is burned and used in industrial boilers.

What are the negative effects of coal?

Several principal emissions result from coal combustion:

  • Sulfur dioxide (SO2), which contributes to acid rain and respiratory illnesses.
  • Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses.
  • Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease.
