Many people overestimate the environmental impact of air travel. It's "only" about 2% of global energy consumption. Not nothing, but also not that significant.

It's "only" about 2% of global energy consumption. Not nothing, but also not that significant. There are much bigger energy wasters that can be targeted.
- fulafel 8y agoIt's the other way around unfortunately, people underestimate it: The effect of air travel on global warming is much higher, due to emissions effects in the upper atmosphere. Eg WP says 'Emissions weighting factor (EWFs) i.e., the factor by which aviation CO2 emissions should be multiplied to get the CO2-equivalent emissions for annual fleet average conditions is in the range 1.3–2.9' And air travel is growing at a steep rate because air travel has gotten so cheap and big populations in developing countries take up air travel.
