16. Appendix: Samples from slide deck we used for the GHG rollout in Croton with our residents and village staff and volunteers
19. 3 sectors to count For a full inventory, 3 different sectors need to counted. Governmental Sector Commercial Sector Residential Sector 1. Direct emission exhaust from vehicles fuel oil combustion, etc. 2. Power emission electricity from grid 3. Indirect emissions employee commuting solid waste disposal fertilizer & solvent use, etc. Croton will use 2010/2011 data for these 2 Croton used 2007 data

23. what’s our tonnes? pie chart The total cost of the energy consumed by each sector is displayed, together with the percent of the overall greenhouse gas emissions the energy consumption for that sector produced. We sorted these by largest to smallest emission source, with building and facilities as the #1 emitting sector. Notice that if we sort by largest to smallest cost, water delivery would be #1 most expensive sector, followed by buildings and facilities.

30. #3: US family’s emission pie Typical US family’s annual greenhouse gas emissions pie: www.crotononhudson-ny.gov Lessons from GHG Emissions Baseline Inventory: Communities & Climate Action (Fall 2009) (Adapted from: Vandenbergh et al (2008) Individual carbon emissions: low hanging fruit . UCLA Law Review.) See also http://behavioralwedge.msu.edu/ Fact: Each gallon (3 . 7 liters) of gasoline burned produces 19 . 4 pounds (8 . 8 kilograms) of carbon dioxide emissions. The average US automobile emits 5 . 7 tons (5 , 200 kilograms) of carbon dioxide per year.

33. http://bit.ly/Croton_Firehouse_SolarPanels The Grand Street Firehouse consumed 52,459 kWh in 2007 at a utility cost of $5,988. The solar electric panel may generate 20% or more of the building’s electricity in 2009-2010. (Clean energy output should be about 12,000 kWh and represents and 8,000 kg ( 17,600 pounds) of avoided CO 2 e emissions . NYPA provided a grant that paid for the PV panel. The Village bore the installation costs. . www.crotononhudson-ny.gov Lessons from GHG Emissions Baseline Inventory: Communities & Climate Action (Fall 2009)

35. #2b: #1=Water Dept: 400,000 gallons/year Emission sources within Water Dept The dept-wide figures include water delivery total (369 t) plus heating/cooling for buildings operated by water dept (14 t) for 383 total tonnes. (Note on units: scale in tonnes is same for both figures; 1 metric tonne = 1 long ton = 2,204 pounds) } www.crotononhudson-ny.gov Lessons from GHG Emissions Baseline Inventory: Communities & Climate Action (Fall 2009)
36. #2b: #2=DPW Dept: 7,455 tons/yr solid waste collected Emission sources within DPW Dept (excluding street lighting) (Note on units: scale in tonnes is same for both figures; 1 metric tonne = 1 long ton = 2,204 pounds) www.crotononhudson-ny.gov Lessons from GHG Emissions Baseline Inventory: Communities & Climate Action (Fall 2009) }
37. #2b: #3=Fire Dept: 3 firehouses Emission sources within Fire Dept: 188 tonnes emitted by 3 Firehouses combined, compared with 191 tonnes from Mun. Bldg. with its 24/7 Police Station. (Note on units: scale in tonnes is same for both figures; 1 metric tonne = 1 long ton = 2,204 pounds) { www.crotononhudson-ny.gov Lessons from GHG Emissions Baseline Inventory: Communities & Climate Action (Fall 2009) }
38. Energy & costs per resident Emissions (lbs/resident) Energy consumed (kWh/resident) Energy cost ($/resident) Buildings & Facilities Vehicle Fleet Water Delivery Streetlights Wastewater Indirect Emissions Big “jumps” from energy to cost show up in those sectors MOST reliant on electricity which is MORE expensive per unit of energy consumed than other fuel sources: water and waste water (electric pumps). Note on energy units: 1 MMBtu = 1 millions Btus (therms) = 293 kiloWatt-hours (kWh) www.crotononhudson-ny.gov Lessons from GHG Emissions Baseline Inventory: Communities & Climate Action (Fall 2009)
