1. 2007 Emissions Inventory

2. Topics First emissions inventory under Clean Air Action Plan (CAAP) Emissions inventory methodology Cargo throughput changes Conclusion: Although cargo volume increased, emissions declined–in just the first year of CAAP

3. Key Air Quality Factors Green Port Policy adopted January 2005 CAAP adopted November 2006 to cut emissions at least 45% by 2012 The 2007 emissions inventory captures impacts of early CAAP measures State’s vessel auxiliary engine low-sulfur fuel rule became effective in January 2007

4. What We’ve Been Working On Developed methodology with Port of Los Angeles Coordinated with regulatory agencies Analyzed 2007 data Estimated greenhouse gas emissions Validated results & compared to 2005

5. Cargo Activity 2005 vs. 2007 Activity20052007Change Vessel Calls3,1662,700-15% Containerships1,3841,358-2% TEUs6,709,8187,312,6459% Average TEUs/Call4,8485,38411% Fewer ship calls Larger vessels More cargo containers per ship call

6. Changes from 2005 to 2007 Changes due to: –Agency emission estimating methods –Better data Estimation of greenhouse gas emissions

7. How to Compare 2007 to 2005? Inventory = activity record + estimating methodology If methodology changed in 2007, then we re-estimated 2005 activity records using 2007 methodologies Important to note: Activity for 2005 was not adjusted

8. Emissions, All Sources,2007 vs. 2005 TEUs increased 9% NOx and CO increased but less than TEUs Diesel particulate matter (DPM) declined 21%.

9. Comparison 2007 to 2005 Greenhouse gases increased, but not as fast as cargo volume

10. Vessel Emissions 2007 vs. 2005 Particulate matter declined substantially Low-sulfur fuel Green flag vessel-speed reduction

11. Truck Emissions 2007 vs. 2005 With more cargo, truck emissions increased although low-sulfur fuel cut SOx Clean Trucks Program, beginning October 2008, will reduce truck emissions 80% by 2012

12. Harbor Craft Emissions With more cargo, harbor craft emissions increased although low-sulfur fuel cut SOx

13. Yard Equipment Emissions Cargo-handling equipment produced lower emissions, especially SOx, with use of low-sulfur fuel

14. Train Emissions Cargo is shifting from trucks to trains, which reduces emissions But more rail cargo is increasing train emissions

15. Emissions per TEU Increased efficiency With better technology and cleaner fuels, cargo activities are producing less air pollution per unit of cargo

16. Next Steps Briefings on the 2007 Emissions Inventory Collect data for 2008 Emissions Inventory Finalize Rubber Tire Gantry (RTG) crane load factor study New rail methodology with better rail activity data Continue coordination with air agencies

17. Summary Port-wide particulate matter (PM), hydrocarbons (HC), and sulfur monoxide (SOx) emissions decreased in 2007 from 2005 levels despite a 9% increase in TEUs Nitrogen Oxide (NOx) emissions only increased 1% from 2005 Ocean-Going Vessels, the leading source of most port air pollutants, decreased emissions with increased compliance with Vessel-Speed Reduction Green Flag Program, fuel-efficient slide valves, and switching to cleaner fuel

18. More Summary SOx emissions decreased for all source categories due to use of Ultra-Low-Sulfur Diesel in 2007 Rail and truck emissions increased with cargo increases, except for SOx emissions Reduced truck gate idling due to PierPASS off-peak gates

19. More Improvements Are Coming Clean Air Action Plan –PHL Operating Agreement –Clean Trucks Program –Vessel Speed Reduction –Vessel Fuel Incentive –Technology Advancement Program Green Leases CARB Regulations –Cargo-Handling Equipment –Ocean-Going Vessels –Harbor Craft –Drayage Trucks
