Does an offset in the airlines' emission of CO₂ make any difference?
by Alberto Boretti
International Journal of Global Warming (IJGW), Vol. 25, No. 2, 2021

Abstract: The airlines' emission of CO₂ was considered a major environmental threat to the environment, driving the need for immediate carbon offsets and drastic reductions by 2050. The Covid19 'experiment' demonstrates as a drastic reduction of the airlines' emission of CO₂ over 1 year had no impact on the atmospheric concentration of CO₂. The atmospheric concentration of CO₂ is the result of a much more complex situation where the changes to the environment, in general, depend on many anthropogenic and natural forcings. This makes the offset of the airlines' emission of CO₂ a purely philosophical exercise unable to make any difference in the real world.
