We need mineral based carbon removal (weathering) or direct air storage and capture. Microsoft has a nice report what they bought and how long the carbon is captured: https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE4MDlc https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE... > More than 99% of the carbon removal volume we selected was from natural solutions with durability terms of 100 years or less, such as forest and soil projects. Looking ahead, we hope to increase the overall durability of our portfolio by helping to expand the market for long-term engineered solutions such as direct air capture and storage. They are contracting 500 MtCO2 removal from Carbofex, which is producing Biochar (plant coal) and label that as a medium term solution (carbon is taken out for 800 years). If that Biochar is stored secludedly that could be a method to get it completely out of the cycle https://www.carbofex.fi/Home https://www.carbofex.fi/Home
