Yeah, let's use a computationally heavy task that contributes to burning coal and gas releasing CO2 into the atmosphere to reduce a slight fraction in emission so we could pat ourselves on the back.
(Though slight caveat for any nit-pickers. The warming isn’t related to emissions. The contrails essentially create a blanket that traps heat in the earth’s atmosphere - the BBC article linked mentions this)
