All of global aviation, passengers and freight, constitute around 2% of humanity's CO2 emissions. I know it's a great pincushion--who can avoid hating airlines?--but it's a staggeringly tiny contributor to climate change.
- burkaman 7y ago2% is not "staggeringly tiny". Also, the only source I can find for that is the airlines themselves: https://www.iata.org/pressroom/facts_figures/fact_sheets/Documents/fact-sheet-climate-change.pdf https://www.iata.org/pressroom/facts_figures/fact_sheets/Doc... According to the IPCC, CO2 emissions are only 1/4-1/2 of aviation's impact on climate change. In 1999 they estimated the total impact as 3.5%, and projected out what will happen as aviation use increases, which it has. - https://en.wikipedia.org/wiki/Environmental_impact_of_aviation#Total_climate_effects https://en.wikipedia.org/wiki/Environmental_impact_of_aviati...
- kansface 7y agoAccording to literally the first thing I found on the Internet, the airlines take in about 1% of the world's GDP which doesn't sound like a great deal when they emit twice that much in CO2. However, I'm guessing the businesses they support that wouldn't exist otherwise easily make up the difference. I'd guess ~10% of the GDP (most international tourism, shipping, business meetings).
