2300 trees and 2.2 megatons eh? My simple mind figures the amount of CO2 captured by a tree cannot be more than the amount of dry weight in a tree. 100 ton trees sound awfully big.
Dry weight of the tree is the carbon element of the CO2, so carbon dioxide offset is something like a multiple of 3 different from dry weight. Doesn't make you any less right though, very well spotted!
I invited scrutiny of the figures very early on in this but you are the first to notice. The 2300 trees are planted regardless of what anyone says and the land and planning for the other >>1 million trees between the UK and the US sites are also for real and disclosed.
Somewhere in our haste putting up the website and subsequently linking on the thread, after we took on the challenge, it appears an M has been used instead of K on the website and therefore the slides, and this has subsequently not been flagged until now, so thank you! We have a new website on the way and this mistake will be remedied as a matter of urgency. Possible also could be a failure to convert between kg and tons.
Once our initial calculations had been made and the results displayed, it was not necessary to do any further calculations, or further scrutinise those we had done until we had raised funds to plant further saplings, which has been a much slower process than we had hoped, as I am sure you have seen.
Our calculation of one metric ton of CO2 for one tree on average stands, this is based on proportionate analysis of trees planted to the spacing recommended by the UK forestry commission, and the number of those trees which will reach full maturity from those planted. This is actually a low ball estimate on purpose so that we can ensure that we are doing what we say we are in terms of having positive environmental impact. Dry weight of hardwoods left to grow to permanent forestry is often more than 1 tonne, and this does not include the carbon which remains in the soil from decomposed leaves.
We are still very much Carbon positive, if you run the calculations up until now. Thank you for raising this, if you spot any other slip ups please dont hesitate to mention them as soon as they emerge! It is no surprise that we were met with such skepticism - although very surprising no one else mentioned this sooner, given the numerous other objections I have had to address since starting this thread months ago.
