Council Sustainability Committee: April 16, 2024
Final 2021 and Preliminary 2022
Community GHG Emissions Inventories
About Greenhouse Gas Inventories
• Conduct community inventory
annually
• Estimate Greenhouse Gas (GHG)
emissions and their sources
• Evaluate if we are on track to
meeting our reduction targets
• Doesn’t measure all emissions nor
reflect all local GHG reductions from
policy and programs implemented
3 COVID-19 Impacts
• Less travel resulted in
lower transportation
emissions for 2020-2022
• Trend is unlikely to
continue long-term
• The 2023 inventory will
provide more insight on
the “new normal” post-
pandemic
4 Community GHG Reduction Targets
5 • Current adopted targets are to
reduce emissions 80% below
2005 levels by 2050
• Council adopted resolution to be
carbon neutral by 2045
• CSC expressed support for striving
for decarbonization by 2035
Inventory Methodology
6 • Prepared using national standard –
“U.S. Community Protocol”
• Measures:
o Energy used
o Water consumed & treated
o Organic waste landfilled
• Estimates:
o On-road transportation
o Off-road mobile equipment
