It is estimated that about 80% of the world&amp;#x27;s adults have never taken a flight, and 94% of the world&amp;#x27;s adults have not taken a flight in over a year.&lt;p&gt;So, the real picture is that this 2.5% of global CO2 emissions are caused by as few as 6% of the population, who also are incidentally the richest and bear a high personal carbon footprint in other domains than transportation.&lt;p&gt;Also please remember that the aviation sector is growing, and therefore its global contribution to GHG emissions will grow as well in the future. Discounting the carbon footprint of the aviation sector based on today&amp;#x27;s numbers is a mistake.&lt;p&gt;If you do not want to impede on your ability to travel, you shouldn&amp;#x27;t object to it for the 94% of the population that want the same thing as you, and when it becomes available to them the aviation sector&amp;#x27;s emissions will increase 15-fold.</text><parent_chain><item><author>dannyw</author><text>The aviation sector currently accounts for about 2% of global emissions.&lt;p&gt;Is the ability to travel, including all the business, leisure, and cultural exchange benefits worth less than 2% of our carbon footprint?</text></item><item><author>miketery</author><text>Being a part of society implies a social contract and some social control, it’s not black and white.
