Carbon dioxide (CO2) is the primary anthropogenic greenhouse gas responsible for global warming.

Although carbon dioxide is a naturally occurring gas, it is also released into the atmosphere as a result of:

  • biomass
  • fossil fuel combustion (as a by-product)
  • land-use changes
  • various industrial processes

Moreover, carbon dioxide is given a global warming potential of 1 and all other greenhouse gases are measured against it.
