Globally, we need to reach:
2 tons CO2/yr
The Typical Global Household Emits:
10 tons CO2/yr
The Typical US Household Emits:
50 tons CO2/yr

7. RECOMMENDATIONS ENGINE Actions ranked by GHGs, $ & “Difficulty”
Sample of Calculations
Transportation:
Trading in vehicle for more efficient model
Buying a new more efficient model
Drive X miles less per week
Take public transportation X miles per week
Keep tires inflated
Get regular tune-ups
Housing:
Replace X light bulbs
Purchase Energy Star appliances (fridge, dishwasher, clothes dryer, etc.)
Turn down thermostat in winter
Buy programmable thermostat
Turn down water heater
Food:
Diet Switching: no red meat; lacto-ovo vegetarian, vegan
Buy Organic
Buy local
Goods:
Buy second hand goods

19. CARBON FOOTPRINT MAPPING TOOL
Cooling

20. WHAT FACTORS INFLUENCE CARBON FOOTPRINTS?
Electricity:
CDD, $/kWh, US State of Residence, Energy Mix
Nat gas:
HDD; % of households using NG for heating, US State of Residence
Vehicle Miles – Gasoline (in development):
Population density, Access to PT, household size, income, # adult drivers…
Food, Goods, Services
Income - Housing Expenses (need to account for luxury goods)

22. COOL SCHOOLS CALCULATOR
Piloting Calculator with Head Royce Elementary
Energy (enter monthly data)
Commute
School lunches
At home or in cafeteria
Compares GHG footprint to nutrition
Zero emissions from school or home garden
Basic Procurement
School supplies, books, construction, A-V, etc.

23. COOL COMMUNITIES TOOLKIT
Piloting Approach with City of Davis
Seeking to eventually reach ½ of Davis residents
Pilot Project:
100 household to use CoolCalifornia in October
Using David Gershon’s Low Carbon Diet
Will follow up with online survey to track results
