FACTS:
All landfills generate landfill gas.

Landfill gas is generated during a 30-50 year period as waste decomposes, and continues after the closure of the landfill.

Landfill gas consists of approximately 50% methane and 50% carbon dioxide.


Both methane and carbon dioxide are greenhouse gases.


One tonne of methane is equivalent to 21 tonnes of carbon dioxide, in terms of global warming potential.
