Private jets are an ecological lightning rod. Climate campaigners often berate flyers for what they see as unnecessarily polluting the planet, such as the six-minute flights by the Kardashians, Elon Musk, and Taylor Swift that you read about. Climate protestors sometimes block private jet terminals and vandalize the aircraft.
While flying private does emit more carbon per person than riding coach or even first class, the overall scale of the pollution is relatively small. Aviation is responsible for 2% of global carbon emissions, according to the International Civil Aviation Organization, and private jets account for 2% of that 2%.
