2 Global Temperatures Rising Source: NASA Goddard Institute for Space Studies, January 11, 2008 Source: Washington State Dept of Ecology; cts.htm cts.htm

3 Energy needed to manufacture product Energy consumed using product GHGs released by product during use End-of-life GHG emissions –when product is landfilled, incinerated, recycled How do products have climate change impact?

4 Transportation Transportation Sector = Largest GHG Emitter Accounts for ~1/3 of all CO2 emissions nationwide Source: Energy Information Administration,

5 Sustainable Bus Fleets

6 Sustainable Biofuels? Roundtable on Sustainable Biofuels is developing an international standard: e65660-en.html e65660-en.html Key criterion: Sustainable biofuels reduce GHGs (measured using consistent criteria)

7 Slow Transport Transportation by ship is most efficient Rail Freight is a close second Road Transport: 4X more CO2 than Rail) Air Freight is worst: 6X more CO2 than road; 30X > rail

8 Local Purchasing Win Reduces GHG emissions in the transport sector Strengthens local economy by creating green collar jobs and increasing tax revenue

9 Facility Energy Use Source: US Department of Energy; Buildings account for: 70% of electricity consumption 39% of energy use and carbon dioxide (CO2) emissions

10 Energy-Efficient Lamps and Ballasts Reduce mercury from power plants Decrease # of lamps needed to light spaces Specify Super T8s (SPX, XPS, High-lumen), T5s and extra-efficient ballasts Set minimum efficiency (lumens/watt) CRI (80+) Eliminate inefficient lamps, ballasts & fixtures from contracts (T12, mercury vapor, circular T9s)

11 LEDs Exit signs Traffic signals Parking lot lights Hallway lighting Elevator lights Replacements for pin-based CFLs Task and track lighting Underwater lighting for pools Pathway lighting (outdoor lighting) Holiday lighting

12 Exit Signs Incandescent light bulbs Inefficient: use about 40 watts Bulbs last about 3000 hours (~4-6 months) Fluorescent lamps More efficient than incandescent (5-15 watts) Contain mercury (5-30 mg) Bulbs last about 7,500 -10,000 hours (9-12 months) LEDs Even more efficient (<1-5 watts) Bulbs last up to 100,000 hours (up to 10 years) Self-luminescent Use no energy

13 ENERGY STAR-rated Products List Appliances: washers, dishwashers, refrigerators, etc. Heating and cooling equipment: furnaces, boilers, air conditioners, fans, etc. Lighting equipment: compact fluorescent lamps, fixtures, exit signs, traffic signals, etc. Office equipment: computers, copiers, printers, etc. Electronics: telephones, TVs, DVD players, etc. Miscellaneous: food service equipment, vending machines, windows, etc.

14 Federal Energy Management Program US Dept of Energys FEMP runs an Energy Efficient Products Program to help purchasers identify and calculate the life-cycle costs of highly-efficient energy-using products, including: HVAC equipment Appliances Windows Roofing Electric motors Lighting technologies Office equipment Water-using devices See:

15 Appliances Assumptions: 1 unit each, electricity rate $0.09/kWh, water rate $4.158/1000 gal, gas rate $1.1/therm Data based on ENERGY STAR calculators from

16 EPEAT Electronic Product Environmental Assessment Tool Environmental specifications for computers: 23 required and 28 optional criteria across 8 categories Meet standards for ENERGY STAR (required) Renewable energy accessory available (optional)

17 Printers, Copiers, Scanners & Faxes ENERGY STAR models use ~1/2 energy of standard models EPEAT imaging equipment standard in development Order with duplex function and network capable (instead of individual machines) Purchase All-in-One units when possible A single ENERGY STAR multi-function device will reduce ~320 pounds of CO2 over 6 years vs. printer scannercopierfaxall-in-one

18 Renewable Energy Procurement Decisions Type: Solar, wind, biomass, hydro, etc. On-site versus offsite generation Small scale versus large scale


20 Water & Energy Linked Source: California Energy Commission, 011-SF.PDF Water-related energy use consumes 19% of Californias electricity, 30% of its natural gas The nations water & energy use are inextricably entwined. Energy is needed to pump, treat, transport, heat, cool, and recycle water. (California Energy Commission) Running hot water for 5 minutes = 60 watt bulb for 14 hours Water conservation saves energy at ~60% of cost of energy conservation

21 Water Sense Label Third-party tested and meet EPAs efficiency specifications WaterSense certifications exist or are in development for the following product categories: –Bathroom sink faucets (certified for efficiency and adequate flow) –Landscaping irrigation services (certifies professionals) –New homes –Showerheads (in development) –Toilets (certified for performance and efficiency) –Urinals (in development) –Weather- or sensor- based irrigation control technologies (Source: )

22 GHGs from Food Production Systems What matters most is how food is produced 83% of GHG emissions are production related Methane from beef and dairy production 11% from transportation

23 Reducing Municipal Foodprint Change practices of cafeterias, concessions, vending machines, special events, other food service operations Purchase less red meat and dairy; increase chicken, pork, fish, eggs and veggie proteins Buy organic and/or sustainably grown food Buy local, seasonal, fresh, unprocessed food; avoid air freighted food Reduce bottled water and other packaged goods Reduce food waste; compost whenever possible

24 Paper Calculator

25 EPAs Recycled Content (ReCon) Tool Calculates energy benefits and GHG emissions reductions from purchasing products with recycled content Available both as a web-based calculator and Microsoft Excel spreadsheetweb-based calculatorMicrosoft Excel spreadsheet waste/calculators/ReCon_home.html

26 Metric for Recycled Plastic One ton of CO 2 equivalent is eliminated when purchasing: 4 hexagon-shaped recycled plastic benches (98% postconsumer waste) 15 recycled plastic park benches with backs (98% postconsumer) 100 recycled plastic, 96- gallon wheeled yard waste carts (25% postconsumer )

27 ~25% of trees (by volume) are cut to manufacture paper products Larger trees can better sequester/fix CO2 FSC certifies/lists paper products and building supplies that are derived from sustainably managed forests Many products contain recycled content See

28 GHGs from Janitorial Maintenance Products Pressurized air dusters often contain chlorodifluoromethane, a potent GHG Alternatives include mini keyboard vacuums and squeezable bulbs Some aerosol products contain CO2 as a propellant

29 How to Pay for Energy-Efficient Products Life-cycle budgeting Revolving loans Utility rebates Energy conservation service agreements Grants Cooperative purchasing

30 Operated by the California Energy Commission, offers free technical assistance to publicly-funded K-12 schools to: –Conduct energy audits –Review equipment specifications –Evaluate design plans and proposals Bright Schools Program
