Climate Pathways w/ greatest climate ROI: - 2 concrete based using CO2 during mixing - 2 chemicals based, when producing formic acid through hydrogenation of CO2 & carbon monoxide through dry reforming of methane https://pubs.acs.org/doi/10.1021/acs.est.1c01109 ### Supertrees Hacking photosynthesis for supertrees that capture more carbon through a company called "Living Carbon". Interesting is their innovations to slow tree decomposition rates. ..through a process that enables trees to take up copper and nickel, which act as fungicides.. Because Fungi speeds up the decomposition of wood, leading to loss of CO2.
