Do anyone remember a couple months ago the 2021 United Nations Climate Change Conference? The prime ministers and presidents of the different countries arrived in huge private jets with really large entourage, with huge limos and "security" vehicles, just in case anybody didn't know who they were. With that kind of political mindset, where they can pollute all they want in order to show off their power, do you think they are gone to do something about private aircrafts and vessels that most of them have? It's very naive to think so. Like other person said in the comments, I don't know how true or how false this article is, but I won't doubt it too much.
