You can see for yourself: https://ourworldindata.org/ghg-emissions-by-sector https://ourworldindata.org/ghg-emissions-by-sector Shipping is 1.7% of global emissions while aviation 1.9%. The immoral aspect is that jet fuel at the moment is literally tax free pretty much anywhere in the world. Not because of private jets but to prop up airlines from going insolvent. Not every 'fairness' discussion has to be a 'eat the rich' polarization. If we are looking at % of emissions then all of this is a distraction, arguably the best bang for buck is to get energy storage + renewables and reduce energy from coal production. If we are looking at it from a social fairness aspect than jet fuel should absolute be taxed.
