Other green initiatives announced by the tech company include putting emissions information on its airline fares search engine, Google Flights. From Wednesday, users around the world will be able to see the carbon emissions per seat for every flight and lower carbon flight options
Will this nudge people to take lower emission flights?
Doing some quick searching, I am not quite sure about the calculation model tho...
EI A320 - 107Kg
FR B738 - 114Kg
KL B738 - 114Kg (same as FR, but lower density, why the same?)
KL E190 - 153Kg
BA A320 - 73Kg
EI A320 - 76Kg (although I think it is higher density than BA as there is no business class)
EI A321Neo - 85Kg
BA A319 - 86Kg
EI A330 - 98Kg (surprised this is the least efficient?)
