“Good Tourism” Insight Partner SUNx — Strong Universal Network — has again called for a “moon-shot” effort by the aviation and air transport sector to be zero-carbon by 2050.
During FITUR, the international tourism fair in Madrid, SUNx Co-Founder Geoffrey Lipman said that the aviation sector’s decarbonisation pledge — for 50% of 2005 levels — was now more than a decade old and was “no longer in the mainstream of climate resilience thinking”.
