<p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:Arial'>I
am conducting some work considering transatlantic flights. Please could someone
explain to me why there is such a difference in the CO2 emission factor for Jet
Kerosene between North America and the <st1:place w:st="on"><st1:country-region
w:st="on">UK</st1:country-region></st1:place>. Is the fuel composition
that different? Or am I doing the calculations wrong? <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:Arial'><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:Arial'>There
is a growing number of airlines offering offsetting (love it or hate it –
I’m just doing my job) – but is there an international standard for
this. I have run the IPCC tier 2 on methodology for the data I have and
used the IPCC default EF – but when I compare the tonnages with the those
for equivalent flights with other companies then I am coming out much higher.
In reviewing the <st1:place w:st="on"><st1:country-region w:st="on">UK</st1:country-region></st1:place>
emission factor for Jet Kerosene they are reporting at 0.853 tonnes CO2 per
tonne JA versus the IPCC default of 3.567.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:Arial'><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:Arial'>Probably
this is something that has been discussed before but ever keen to bring all
integrity possible to the issue of offsetting – I need to understand what
is going on or where I am going wrong with my calculations!<o:p></o:p></span></p>
