Environment Canada has created a Greenhouse Gases (GHG) Calculator for Waste Management to assist municipalities and other users to estimate GHG emission reductions from different waste management practices, including recycling, composting, anaerobic digestion, combustion, and landfilling.
The calculator helps users construct two distinct scenarios (baseline and alternative) for managing the same quantity and composition of municipal solid waste. The calculator then automatically determines the GHG emission reductions that will result from implementing the alternative scenario. Other information such as landfill gas recovery practices, and the transportation distance can also be entered into the calculator.
The life-cycle methodology used in this Calculator is based on the United States Environment Protection Agency’s Waste Reduction Model (WARM). However, the data underpinning the calculator comes from Canadian sources such as Statistics Canada, and research into Canadian material-specific GHG emission factors.
