Landfills emit less cO₂ than do Waste-to-Energy facilities
But the methane emitted by landfills from the same waste is far more potent than CO₂
Once in the atmosphere, methane is much better at trapping heat than CO₂.
continUously emitted from landfills over decades
When it comes to climate change, a little methane has a big impact
Scientists compare the strengths of different gases using global warming potentials over different time periods.
Over 100 years, methane is 28 - 34 times stronger than CO₂
However, over 20 years, a timeframe increasingly seen as relevant to combating climate change,
METHANE IS 84 TIMES STRONGER.
