SOLID WASTE MANAGEMENT
The decomposition of waste in landfills creates methane, a potent heat-trapping gas that contributes to climate change. Avoiding waste accumulation in landfills through programs that reduce, reuse, and recycle waste can reduce methane emissions. For example, the city of Toronto produces its greatest greenhouse gas emission reductions, as well as generates a significant sum of income each year, through capturing landfill gases for use in power production.
