Apportionment technique explained: Upon the advice of Offsetters Inc, we took a group of GHGs and their GWP. We added up how many tonnes of oxide would be needed to remove 1 CO2e from each gas. Once we had that total weight, we totalled the CO2e as well. Then we divided the total CO2 e by the number of tonnes that were used, to get an average CO2 per tonne of oxide, and voila, we had our potency, which came to 520 CO2e/1 T O*.
Because only 2% of the atmospheric GHGs are these gases, we calculated 2% of 520=10.4 which then is converted to hydroxyl=22.1 CO2e. We then add the 98% CO2 value at 1:1, and obtain 23.08 CO2e per tonne of oxide released. Our ceramics release just over 3tonnes of oxide per year each. Here is a bitmap showing the gases that we included in this calculation:
We total up all of the abundances of the GHGs and pollutants in a spreadsheet and this guides the final apportionment calculation:
Please note all of the positive consequences that result from releasing the OH* to the atmosphere at scale here: https://vivacundliffe.com/2022/10/01/hydroxyl-dispersal-at-scale-has-only-positive-benefits-for-humanity-2/
Thank you for your interest! Please note that as we scale, our offset price will lower gradually, which makes this the most affordable, best in class DAC method in the market.
