We Need Quitters Amongst the Super Emitters

In 2018, airlines generated an estimated 1 billion tonnes of carbon dioxide, whilst paying no carbon taxes (there is no duty on aviation fuel). In deed, the aviation production of 'greenhouse gases' rose by 32% between 2013 and that pre-Covid-19 year (they were also pretty effective in spreading the virus around the globe!). The airlines hope to return to 2018 emission levels by 2024 (which is bad news for people who are hoping for a needed curtailling of climate change). A study has estimated, however, that frequent flyer, 'super emitters' (who make up only 1% of the world population), generated 50% of the 2018 global aviation emissions (https://www.theguardian.com/business/2020/nov/17/people-cause-global-aviation-emissions-study-covid-19). US air passengers had, by far, the biggest carbon footprint. I know it's a big and populous country but US emissions exceeded the combined outputs of the next 10 countries on the list (including Australia, Germany, Japan and the UK). So we have a situation where a tiny section of the world's population, is driving climate change, impacting negatively on a majority who rarely (or never) take a plane. I do think that some kind of corrective balance is urgently needed but am unconvinced that the aviation industry can become 'greener' within the needed time frame (in spite of some of their recent claims). I think we have no choice other than to make aviation a less common means of transportation (of people and goods).
