Transcript of Chapel Hill Carbon

Total solid waste and recycling emissions:
80,812 mtCO2e

Emissions per capita:
1.38 mtCO2e

Percent of total Town of Chapel Hill emissions:

Food Emissions
Producing, processing, transporting, storing, and selling food on scales of hundreds or thousands of miles.
Food-dollars can reliably quantify emissions.
Internal combustion engines from passenger and freight vehicles release significant GHG's including carbon dioxide, methane, and nitrous oxide
Solid Waste and Recycling
Produced by a community or disposed of within a community
Emissions resulting from management and the natural decay of solid waste
Upstream emissions from recycled goods

Other Emissions
Long-distance freight
Wastewater treatment

Greenhouse gases such as methane and carbon dioxide trap earth's heat and contribute to global climate change
Electricity and Natural Gas
Food Emissions
Solid Waste
Other Emissions
The purpose of this project
was two-fold:
Carbon Inventory
Town of Chapel Hill
2012 Baseline

anthropogenic sources are thought to greatly exacerbate this trend
limiting sources of GHGs now will help minimize climate change
Provide the Town with a snapshot of current emissions so that we can begin thinking through solutions
Provide a baseline and process that can be repeated so that trends can be assessed
Natural gas and coal (among other resources) are often combusted for energy production. This combustion produces by-products including GHGs.
Important Utilities Figures

Total other emissions:

99,531 mtCO2e

Emissions per capita:

1.7 mtCO2e

Percent of total Town of Chapel Hill emissions:


Total Electricity and NG emissions (including upstream NG emissions):


Emissions per capita (electricity):
10.63 mtCO2e
Emissions per capita (natural gas):
2.6 mtCO2e

Percent of total Town of Chapel Hill emissions:

Important Solid Waste and Recycling Figures
Total Transportation Emissions:
93,009 mtCO2e
(99% from passenger vehicles)
Emissions per capita:
1.59 mtCO2e

Percent of total Town of Chapel Hill emissions:

Town per capita VMT:
4697 miles/year
National average per capita VMT:
13,476 miles/year
Important Transportation Figures
So how do we compare?
With a town
With a city
What a low carbon community looks like:
Vehicle Miles Traveled
Important Other Emissions Figures
Important Food Consumption Figures
Total food consumption emissions:
199,233 mtCO2e

Emissions per capita:
3.41 mtCO2e

Efficient and clean energy sources
Local and in-season food
Public and alternative transportation
Management of solid waste methane
Composting and recycling
We would like to thank
ICLEI Protocol
International Council for Local Environmental Initiatives
Provides consultation and training with the goal of sustainable development.
Recently published community protocol provides formulas to total greenhouse gas emissions.
Broader scope than previous municipal inventory
Inventory next steps
Using the same protocol and data sources, regularly update the inventory
Create a time series to guide policy decisions
Explore more detailed accounting methods
