according to this wiki article, over its lifetime a plastic straw will release 1,46 grams of CO2, while a paper straw will release 1,38 grams of CO2. that’s a saving of 0,08 grams.
and according to this article, a private jet releases 4,9 kilograms of CO2 per mile.
so: assuming you are using one straw per day, a year of using paper straws instead of plastic straws offsets about 0,006 miles of one private jet, or a bit more than 10 meters.
that’s fun.
tbh, the real reason to use paper straws instead of plastic is that they’re much more biodegradable, not so much the CO2 use. we should use way less plastic in general, imo
and it bears mentioning that the CO2 released by private jets still pales in comparison to what the airline industry produces; the average global northerner’s overseas holiday is still very destructive for the environment (tho obviously not as much as a rich fuck using a private jet)
