indicating that the correct figure would be equal to all Hawaii’s domestic emissions. <br />However her analysis did not count any connecting flight emissions, but only the two <br />Hawaii legs of an itinerary. This is resultant from her use of the Hawaii State <br />Greenhouse Gas Inventory, of which she was an author, for visitor data. My findings <br />were based on the Hawaii Tourism Authority’s eight ‘Global Regions of Origin’ visitor <br />data and thus counted ‘connecting flights’ in the itinerary (which has its own <br />problems). 4. Also subsequent to Dr. Coffman’s presentation, the IPCC designated <br />as ‘best science’ on Aviation emissions a method which calculates the global warming <br />potential of ‘non-CO2 emissions’ as twice that of CO2 emissions themselves. <br />Whereas myself and Dr. Coffman had calculated these ‘non-CO2 emissions’ as equal <br />to the warming potential of CO2 itself, using the IPCC endorsed method would bring <br />her calculation of visitor air transport GHG emissions to 1-1/2x the state’s total <br />domestic emissions, and my calculation, including the multiple legs of any visitor <br />itinerary, to 2x the state’s total net domestic emissions. <br />Respectfully submitted as Testimony, <br />Tawn Keeney MD <br />
