Last week, the International Civil Aviation Organization (ICAO) has settled upon a global emissions-reduction scheme that will apply to passenger and cargo flights. The sector currently represents 1.5% of global greenhouse gas emissions, but that is expected to increase to 25% by 2050 due to the fact that more and more people get access to (cheap) flights. The deal does not put a carbon cap or tax (as it exists for all internal European flights) but only requires the airlines to offset their emissions by supporting reforestation projects etc at a cost of 2% of yearly revenues.
My question to you: is this deal an empty box, a typical example of greenwashing? Or do you believe that the sector will do something about emissions voluntarily to curb their emissions?
I looked up the ICAO's 2016 environmental report, and they outline the scenario as shown in the graph below. According to them, it is possible to keep emissions stable while the number of flights and passengers booms, by fuel reduction measures and alternative fuels. So another question: do you think this is reasonable?
