if we look at planting trees or afforestation, then the feeling was that that could remove something of the order of about 3 billion tons of carbon dioxide by mid century. and with carbon capture and storage which, if done right, could also be a net carbon removal technology, that might contribute something like 2 billion tons of carbon dioxide removal by mid century. and then direct air capture, something like three, maybe as high as 5, billion tons by mid century. now, if you add all of those up, you are talking about 10 billion tons of c02 removal by mid century. that might seem like a lot but comparing it to our current emissions, which are 35 billion tons of c02, it only represents about a third of the solution. and so, that means to deal with the other two thirds, we need to get much more energy efficient and if, on top of that, carbon removal technologies can help us along the way, then that is great, but let s not pin our hopes on those technologies alone.

years to really have an impact. it s been estimated that to reduce co2 by a billion tons, you d need a new forest twice the size of california. but together, could technology and nature suck up the c02 mess we re currently making? if we look at planting trees or afforestation, then the feeling was that that could remove something of the order of about 3 billion tons of carbon dioxide by mid century. and with carbon capture and storage which, if done right, could also be a net carbon removal technology, that might contribute something like 2 billion tons of carbon dioxide removal by mid century. and then direct air capture, something like three, may be as high as five, billion tons by mid century. now, if you add all of those up, you are talking about io billion tons of c02 removal by mid century. that might seem like a lot but comparing it to our current emissions, which are 35 billion tons of c02, it only represents about a third of the solution. and so that means to deal
species and this was planted last year, in the last winter, which is a year ago for us now but, as you can see, they are really not getting anywhere above waist height. that really puts emphasis on how we have to conserve our mature forests because this plantation here is going to probably take maybe 20, 30 years to really have an impact. it s been estimated that to reduce co2 by a billion tons, you d need a new forest twice the size of california. but together, could technology and nature suck up the c02 mess we re currently making? if we look at planting trees or afforestation, then the feeling was that that could remove something of the order of about 3 billion tons of carbon dioxide by mid century. and with carbon capture and storage which, if done right, could also be a net carbon removal technology, that might contribute something like 2 billion tons of carbon dioxide removal by mid century. and then direct air capture,
