Waterloo Waste Systems LCA by tonnes CO² eq
•Everything to landfill 60,300•52% Residential diversion, landfill 7,800•60% Residential diversion, landfill 5,100•52% Residential diversion, thermal, landfill - 19,000•52% Residential diversion, MBT, landfill - 28,900
• 52,500 tonnes reduced through diversion
• 55,200 tonnes with 60% diversion
• 79,300 tonnes reduced by adding thermal
• 89,300 tonnes reduced with MBT

GHG Reductions by kt CO² eq
•52% Residential diversion, landfill - 1,200•60% Residential diversion - 1,270 (- 70)•Thermal - 1,800 (-600)•MBT - 2,100(-900)
Remember these numbers only represent 1/3 of the waste. What would they look like if we could increase IC&I diversion to 60%?

Ontario’s GHG Roadmap: Long Term•Ontario is on track to achieve the 2014 target(167 Mt)•Ontario is on track toachieve nearly 70% of the 2020 reduction target(150 Mt)•Need more efforts to Reduce GHGs - Putting a price on carbon - Establishing interim emission reduction targets

Cap and Trade
•Few waste facilities required to report under Cap & Trade•Potential benefits to the waste industry are the creation of offsets:
• Flares or gas collection at landfills
• Composting
• Anaerobic digestion and other organic diversion
• Recycling activities (IC&I)
• Low carbon fuel on energy replacements
• Fleet fuel conversions
MWA Spring Workshop May 2015MWA Spring Workshop May 2015
Conclusion•Significant GHG reduction has already occurred through diversion programs in Ontario.•Increasing diversion across all sectors with results in a decrease in GHG emissions.•The waste industry has a role to play in meeting Ontario’s GHG targets.•Waste industry needs to participate in the identification and development of offset protocols.
