  2. Presentation Topics • Seattle City Light – A Carbon Neutral Utility • Increasing Vehicle Efficiency • Biodiesel: Citywide and at Skagit • Electric Plug In Efforts • Reducing Vehicle Use • City policy • Street Light Relamping Trucks • Smart Grid and Transportation Emissions

  3. Transportation Emissions Management Seattle City Light – Carbon Neutral Utility • Carbon Neutral since 2005 • Greenhouse Gas Advisory Committee recommendations: • Mitigate 610,728 metric tons of CO2 using • a mix of projects and purchasing carbon offsets. • Equivalent to about 135,000 cars off the road for one year.

  4. Increasing Vehicle Efficiency Biodiesel King County Metro buses, City of Seattle fleets, Rabanco Waste Haulers and Washington State Ferries. City Light’s fleets and City of Seattle fleets use a blend of B40 (40% biodiesel, 60% conventional diesel) – except for city emergency vehicles. City Light pays price difference for biodiesel in city, metro, and ferry fleets. Calculated as part of carbon neutral status. Biodiesel tends to gel in extreme cold – suppliers could provide an anti-gelling agent.

  5. IncreasingVehicle Efficiency Plug In Electric Hybrid Vehicles (PHEV) • Three City of Seattle Fleet Prius’ converted • to plug-in electric hybrids: • City Light part of a national effort to study • PHEV’s integration with the electric grid. • Information from data loggers on cars used by City Light • to study the effect on electricity grid load. • U.S. Department of Energy and City Light are funding the • pilot project.

  6. Increasing Vehicle Efficiency Plug In Electric Hybrid Vehicles (PHEV) Greenhouse gas emissions from PHEV Prius’ 25-50% lower than standard Prius. National Resources Defense Council and the Electric Power Research Institute Report states: “Scientists have confirmed that unlike gasoline cars, plug-ins will get cleaner as they get older -- because our power grid is getting cleaner."

  7. Increasing Vehicle Efficiency Plug In Electric Hybrid Vehicles (PHEV) Websites: California Cars Extensive database on PHEV’s http://www.calcars.org/vehicles.html NRDC and EPRI Report on PHEV’s www.epri-reports.org/

  8. Reducing Vehicle Miles Traveled Street light maintenance trucks • Study on diesel fuel use in street light re-lamping trucks: • Currently street light replacement crews ‘spot • re-lamp’ individual street lights on a first come first served basis. • Considering a zone or group re-lamping route for trucks. • Preemptively replacing all old lamps in a section of the city will help prevent random street light burn outs.

  9. 53.4 MT CO2 (projected annual) 21.0 MT CO2 (projected savings) Reducing Vehicle Miles Traveled Preemptive replacement may also reduce greenhouse gas emissions from maintenance trucks: 74.4 MT CO2 (total 2007)

  10. Reducing Vehicle Use City of Seattle Green Fleets Initiative Clean and Green Fleet Action Plan can be found at: http://www.seattle.gov/fleets/ One-Tank Challenge tips: Don’t idle unnecessarily Use bus, pedal bikes and Segways for in-City travel Re-evaluate use of take-home vehicles Hold trainings and meetings “in the field” Plan work routes efficiently Use courier services for efficient package/mail deliveries Carpool to meetings (75% of motor pool use is single occupancy) Ask your fleet coordinator to downsize your vehicle Use the City’s telephone conference bridge for conference calls Have vendor and subcontractor meetings at your office

  11. Smart Grid effects on Transportation What’s all this Smart Grid talk and what does it have to do with cars? The “grid” is all the interconnected electric lines in cities and the countryside. Currently utilities rely on old technology that only distributes electricity. A “smart” grid is like an electric internet – allowing the utility, residential renewable energy systems, and plug in electric hybrids (PHEV’s) to “talk” to each other.

  12. Smart Grid effects on Transportation • Required for PHEV’s to pull power from and deliver power back to the grid when needed. • The smart grid allows active consumer (and appliance) participation – thereby reducing waste and carbon emissions.

  13. Questions?

  14. Increasing Vehicle Efficiency SCL’s Criteria for offsets: 1) High quality and low cost, preference to local projects: - substituting biodiesel in city fleets and providing electric shore power for cruise ships. 2) Mix of local projects and lower price national projects. -Invested in mitigation efforts at DuPont Freon manufacturing facility in Louisville, KY.

  15. Increasing Vehicle Efficiency Biodiesel Skagit River Hydroelectric Dams Timothy Epps – Senior Warehouse Vehicle Manager Biodiesel explored but not used at Skagit. Cold weather problems – biodiesel gels and gums up engines. 5% (B5) Biodiesel – even 5% biodiesel gels in cold. Supplier can provide an anti-gelling agent, but was not explored further.
