3.4. Description of Environment Canada Greenhouse Gase (GHG) Calculator
- Using Canadian GHG emissions factors for materials commonly found in the Canadian waste stream
- Includes anaerobic digestion as a waste management treatment option
- Expands the list of materials included in the calculator to better reflect Canada’s waste stream, i.e., inclusion of white goods and waste electronics
- The use of province specific fuel generation to reflect regional differences in the energy grid mix.
3.5. Description of Model
- Users can alter material tonnes recovered or material revenues to re-calculate impact on WEEE system costs, diversion levels and emissions impacts.
- Users can set a WEEE system goal emissions target (currently set at 215,000 CO2/e). The model calculates the impact on Waste Electronics system costs and recycling rates (To achieve the goal emissions target) by increasing diversion for the materials with the lowest net cost and highest emissions credits.
- Users can select the value of a proposed carbon credit and calculate the potential value of carbon offsets for the WEEE program (by material type).
