COOL CLIMATE : THE PRIMARY RESEARCH How much variability exists in the size and composition

of household carbon footprints across all U.S.

locations?

How much of this variabilitycan be explained by

population density, income,home size, and other

factors contributing to carbonfootprints in urban, suburban,

and rural areas?

HOUSHOLD CARBON FOOTPRINT (HCF)Household carbon footprints are the greenhouse gas emissions required to produce distribute and dispose of all household consumption for one year, including emissions resulting from the purchase use of;• motor vehicles, public transit, air travel,• housing, household energy• food, water, • consumer goods, and • services.

They developed econometric models to estimate household energy, transportation, consumption of goods and services, and total household carbon footprints at fine geographic resolution.

COOLCLIMATE IS AN ESTIMATED CARBON FOOTPRINT

• The models do not measure consumption, but rather estimate demand for goods and services for average households in zip codes using econometric models of national household survey data.

• As such, the results should be considered benchmarks by which measurements may be compared.

• They are limited to only variables available for zip codes and have left out potentially important variables, such as fuel economy of vehicles and local energy policies.

WHAT IS CARLISLE’S ACTUAL FOOTPRINT?

• What data do we have?• What data are we missing?• Do we need a town wide survey?• Real data will help us understand the issues

and can initiate innovation.• We can work with UC Berkeley to analyze

the data.• Develop an action plan for the community.
