| Mar 4, 2020 at 16:08 | comment | added | chaosflaws | The second argument is - at least in part - a consequence of the fact that there simply may not be enough space on earth, let alone in certain countries, where planting trees actually has a measurable, positive effect: ethz.ch/en/news-and-events/eth-news/news/2019/07/… | |
| Mar 4, 2020 at 11:57 | comment | added | Magisch | @THelper spitballing here and using the numbers found elswhere in this thread, according to wikipedia the US has produced 5.400.000.000 tonnes of CO2 Equivalent Greenhouse Gasses in 2018. Thats ~14,8 million tonnes a day. Christopher's answer below assumes non cut down trees sequester about 6 tonnes each for a 20 year old tree, which taking that means you'd need around 1,2 million trees to offset 12 hours of emissions in the USA. So the claim by UKMonkey might be off by a lot, but seems to be at least on the right order of magnitude. | |

| Mar 3, 2020 at 14:57 | comment | added | UKMonkey | I feel it should be added that 10 million trees - if they grew to full size in a day; would offset the carbon emissions for the USA for 12 hours. | |

| Mar 2, 2020 at 22:30 | comment | added | M Juckes | There is also the question of "additionality" -- which overlaps with 1 & 2: is the tree that has been planted absorbing more CO2 than whatever was happening on that bit of land before the tree was planted? | |

add link to offsetting scheme gone bad, added link to report about planting above certain latitude
