Overview of the CoolClimate Calculator Chris Jones Staff Research Associate Berkeley Institute of the Environment, University of California, Berkeley October 2008

THE TEAM Dan Kammen, Faculty PI Dan McGrath, BIE Executive Director Chris Jones, Lead Developer Graduate Students Sally Maki: ’07-’08 – Version 2.0 Kate Foreman: Fall ‘08: GHG mapping – GIS Jeremy Eddy, Fall ‘08: Recommendations Engine Undergraduates Mia Yamauchi, Fall ‘08: CoolSchools Calculator

Climate Action Planning Tools for: households, businesses & communities 1. GHG benchmarking & mapping tools 2. GHG inventory calculators 3. Recommendations engines ($ & GHG savings)

1. CoolClimate Calculator: http://coolclimate.berkeley.edu 2. Carbon footprint mapping tool CoolClimate Tools 3. Climate Action Plan - Recommendations Engine - ranks GHG and $ savings of actions Adjustable Assumptions: 11,000 mi/year $4 per gallon Lifetime = 16yrs Dis. rate = 8%

Climate Footprint of the typical US Household (50 tCO2e) (http://coolclimate.berkeley.edu) 56% Indirect 44% Direct public trans. airlines Auto services Auto manufacturing other fuels natural gas Gasoline electricity water & sewage Financing public trans. Construction Air travel Other fuels Natural gas cereals Alcohol & tobacco Dairy Gasoline Total Snack food Fruit & veg. Electricity furniture. cleaning supplies. Eating out entertainment. Household equip. Meat Clothing education giving healthcare Transportation Housing Food Goods Services

2 tons CO2/yr 10 tons CO2/yr 50 tons CO2/yr 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 http://coolclimate.berkeley.edu Source: http://bie.berkeley.edu/calculator Transportation Housing Food Goods Services

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

CARBON FOOTPRINT MAPPING TOOL Cooling

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)
