> Are airlines even a big source of co2 emission when you compare it with other source I am not an expert but I found this article: https://ourworldindata.org/emissions-by-sector https://ourworldindata.org/emissions-by-sector According to this it looks like passenger aviation accounts for around 1.5% of CO2 produced. Additionally, according to this article: https://www.carbonindependent.org/22.html https://www.carbonindependent.org/22.html the climate impact of flights should be considered with a factor of 2-3 times their base carbon emissions, due to additional effects specific to air travel, like nitrous oxide and ozone emissions. Even at the base rate of 1.5%, that seems high for a single activity no?
