Mass production of biochar and use it as a soil amendment. Sequesters carbon in production, sequesters more in the soil as it encourages biomass formation and encourages even more as plants grown in such soil do better.

> Biochar is charcoal used as a soil amendment. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years.[1] Like most charcoal, biochar is made from biomass via pyrolysis. Biochar is under investigation as an approach to carbon sequestration,[1] as it has the potential to help mitigate climate change.[2][3][4] It results in processes related to pyrogenic carbon capture and storage (PyCCS).[5] Independently, biochar can increase soil fertility of acidic soils (low pH soils), increase agricultural productivity, and provide protection against some foliar and soil-borne diseases.[6]
- roryisok 8y agoThis passage caught my eye : > Researchers have estimated that sustainable use of biocharring could reduce the global net emissions of carbon dioxide (CO 2), methane, and nitrous oxide by up to 1.8 Pg CO 2-C equivalent (CO 2-Ce) per year (12% of current anthropogenic CO 2-Ce emissions; 1 Pg=1 Gt), and total net emissions over the course of the next century by 130 Pg CO 2-Ce, without endangering food security, habitat, or soil conservation. It feels like every other week I read about one approach which has the potential to save us from climate change, if scaled correctly. Suberin rich food crops. Autonomous ships that produce artificial clouds. Biochar. Painting things white. Olivine rock weathering. Greening the Sahara. I don't believe any of these solutions alone is going to save the planet, but surely doing several in concert would help
